description: This talk will give an introduction into the general concepts of power-to-x and then go more into detail on carbon capture and utilization (CCU). CCU is the idea of building up a closed carbon cycle, where CO2 is recycled, towards fuels and base chemicals, under the use of renewable energy. The talk will give insight in the technology, chemistry, possibilities and challenges. While redesigning our electric supply network towards renewable energies, we face the problem of the fluctuating behavior of the renewables. To solve this, higher nameplate capacities need to be installed, as compared to traditional power plants. This frequently leads to high overcapacities, which we should use, as they would be wasted otherwise. Some of this energy needs to be stored for periods where the energy generation is lower than our consumption. The rest can be used to produce all kinds of things that we need. This would allow a sector coupling of electricity with other fields like transport, heat or chemical industry and lead to more sustainable processes in all those fields. If we see this on a global scale, we can also think of a redistribution of energy not only in time and sector of application, but as well in space. This can be realized, by producing fuels and other energy intensive products in areas of the world with a high potential in the generation of renewable electricity, and transport them to places where they are needed. The technologies that would make this possible are often subsumed as power-to-x technologies. The Wikipedia names twelve different x’s: power-to-ammonia, power-to-chemicals, power-to-fuel, power-to-gas, power-to-heat, power-to-hydrogen, power-to-liquid, power-to-methane, power-to-mobility, power-to-food, power-to-power, and power-to-syngas. In addition, one could still think of many more. I want to give a brief introductive overview on these different approaches and then focus on the technologies, which are using carbon dioxide as a feedstock. Here the idea of power-to-x is combined with the aim of a closed carbon cycle. Emitted CO2 would be recycled to products, like fuels, plastics or fine chemicals. While today these are mainly produced form crude oil, in future they could be implemented in a sustainable process cycle. For these carbon capture and utilization (CCU) concepts, like for example electrolysis of water coupled with a second catalytic CO2 reduction step or direct electrocatalytic CO2-reduction, I will present the technical working principles, the chemistry behind it and discuss possibilities and challenges.

description: In the last year, a group of researchers and some industry people at the IETF decided to join forces and design a replacement of the BSD Socket API. This talk gives an overview about why the BSD Socket API is considered harmful for the Internet's future and how TAPS tries to solve this problem. Besides the facts, also gives some hints about how standardisation at the IETF works and why all this takes so long… The BSD Socket API was designed more than 30 years ago. No one back than imagined hosts with multiple access networks, concurrent use of multiple communication protocols, e.g., IPv4 vs IPv6 and TCP/TLS vs QUIC, and incorporating quality of service (QoS), security and cost constrains for setting up communications. The result is a complex ecosystem of APIs and techniques that must be manually combined in order to write state of the art network applications. The talk will give a brief overview on what choices state of the art network applications can make, why the BSD socket API does not support it and how TAPS tries to solve this. I will also talk a little bit about how standardisation at the IETF works, why one may want to get involved and why all this takes so long…

LO! An LLVM Obfuscator

uk: Комп'ютерні науки

description: In this talk we will present how intermediate code transformations can be used to obfuscate code and the advantadges and limitations they introduce. We will also brielfy discuss some techniques that could help detect and reverse code obfuscated in such ways. Despite their limitations, intermediate languages like LLVM-IR provide the best way to write code transformations that work well for all the input and output languages supported by the compiler framework. Usually, this is used to write optimization passes, but nothing prevents you from using them to make the resulting code less inteligible to an external reader. This talk will focus on how different obfuscation techniques can be implemented and used as such passes and what are the limitations that may make implementing, for example, an unpacker a bit harder. We will also cover how some of these techniques can be reversed (specially when perfoming comparative analysis). Keep in mind that although LO started as a way to provide a way to deterministically increase variability in generated code and make finding out the patched flaws harder, many of it's techniques like code flattening or constant expansions are also used by other users of obfuscated code, for example malware.

In the process, get updates about the burning topics we are following in the EU institutions. New European Parliament (EP), new European Commission(EC), possibly Brexit. Nevertheless, the same digital rights we're fighting for. In this talk we will give you an update on what the results of the European Parliament look like, what characterises the new EU Commission and how likely it is that Brexit happens in November 2019. More, we'll update you on the topics we have our eyes on in the EU institutions: the future of content moderation and platform liability in Europe, confidentiality of our communications (ePrivacy), access to data cross-borders by law enforcement, net neutrality, data retention reloaded, algorithms (including upload filters), AI regulation.Finally, we unite the 2 parts: what do the new developments in the EP, EC and Brexity mean for our digital rights fight? How will our rights and freedoms online be impacted by the new environment? Are there new ways and avenues to mobilise and influence policy-making across Europe? There's only one way to find out.

description: Presentation of the Cyborg Foundation, its philosophy, members and developed projects. Based in Barcelona and founded in 2017, CFL is an association that gives voice to non-human identities. The world around us is full of things that our body is not able to perceive. However, what would happen if we could create new senses that would allow us to decide how we want to perceive our surroundings? Supported by a multidisciplinary team, we conform a group of engineers, philosophers, designers and artists dedicated to exploring the relationship between species, machines and organs. With an eye on nature and analyzing the different senses found on living beings, our purpose is the creation of new sense organs to expand human capabilities. Our team is focused on translating the suggested idea to a hardware/software device, that will not only process data but also transmit it to the body through the brain. In the course of becoming cyborg, different phases are found: the creation of the organ, the implantation of it and the acclimatization of the brain and body to the new sense. The brain is a plastic organ that can be moulded. Just like Neil Harbisson says “The brain is like a sculpture to be shaped”. By now, considerable results have been obtained. We will take a closer look at it by introducing the several members whose organs have been already implanted, how this has affected their life and way of interact with the physical world. We will, as well, explain the different senses and its design. Just for a quick view we will talk about: Neil Harbisson - Eyeborg. Color sense antenna. Moon Ribas - Seismic sense Manel Muñoz - Weather station Kai Landre - Cosmic rays In addition, we have the satisfaction of announcing that the CCC will be the first to know about the pioneering technology that we are developing to power the devices.

description: The power of Facebook derives from its control over your digital identity. However, the fundamental technologies behind anonymous (attribute-based) authentication credentials have existed since the mid-90s. This talk will cover new advances in anonymous authentication credentials, how the work was nearly killed by Facebook, and their real-world implementation, including their use in the Nym project's mix-net, cryptocurrency, and decentralized messaging applications. How do we pratically defeat Facebook and build an anonymous internet? Let's start with the building blocks: Getting rid of Facebook Connect using decentralized and privacy-enhancing technologies, then using that as a lever to build the rest of the system. Anonymous authentication credentials have existed since early blind signature schemes, but have historically been both inefficient and required centralized (if often blind!) trusted third parties. New advances such as UnlimitID and the Coconut signature scheme have allowed the creation of "Nym credentials" that are both decentralized and privacy-preserving. We'll go into three use-cases: Mix-networks Credentials allow mix-nets, which provide anonymity at the network level in even a stronger manner than Tor, to both avoid spam (sybil) attacks and grow in a robust, decentralized manner, avoiding the need of proof of work algorithms. Messaging In combination with the new IETF MLS (Message Layer Security) protocol to replace Signal, anonymous authentication credentials can enable a more privacy-preserving messenger. Cryptocurrency If Facebook is building Libra, we'll show how we can take their fundamental design and make it - or any other cryptocurrency - privacy--preserving using Nym credentials Lastly, we'll review how we build the initial work using European Commission funding from NEXTLEAP and PANORAMIX, how Facebook nearly killed the project, and now how we are building from both non-profit and private sector sources, including hiring ex-Facebook employees to work on privacy.

description: In this talk, I will give an overview of the past, present, and possible future of physical security enclosures, i.e., the physical boundary that protects Hardware Security Modules (HSMs) and separates the untrusted outside from the secret data inside the module. I will present an analysis of the hardware security features in some selected HSMs, ranging from sensitive carbon meshes, over light detectors, up to temperature sensors. Since the security of these solutions has recently been questioned and some of them have been discontinued, new technologies have been proposed by several research groups, which will be presented in the second half of my talk. I will give insight into the current research regarding future solutions whose security is based on Physical Unclonable Functions (PUFs). Via this technology, cryptographic keys are extracted from intrinsic manufacturing variation of the enclosure itself. Thus, a violation of the delicate enclosure results in immediate loss of information and thereby voids cryptographic keys - in theory. Finally, I will discuss existing drawbacks and issues which have to be resolved, which currently prevent PUFs from protecting HSMs. Hardware Security modules (HSMs) in servers, such as for VPN or banking applications, are commonly protected via physical security enclosures. This boundary, which consists of a conductive mesh that entirely surrounds the module under protection, is continuously monitored to detect any physical intrusion and subsequently wipe critical data. Since attack tools have improved and some enclosure solutions have been discontinued, a desire for a new technology has emerged. At first, I present state-of-the-art solutions for HSMs which conform up to the highest security level: FIPS 140-2 level 4. Knowledge about these solutions was gained by accurate disassembly of such modules, obtained via a famous online market place. While some solutions have a very delicate mesh surrounding the entire device, others have additional light and temperature sensors that are countermeasures against common physical attacks. However, many physical security enclosures have been discontinued, sometimes due to suspected insecurity, thus, there is demand for a successor. The second part of my presentation focuses on a novel technology for enclosures, based on Physical Unclonable Functions (PUFs). These PUFs, which are currently investigated by several research groups, are uncontrollable minuscule manufacturing variations which are present, for example, in a conductive mesh of a security enclosure. One solution, that I am doing research at, is able to extract femto-farad (10^-15) capacitance variations from electric traces contained in the enclosure. Cryptographic keys are derived from the PUF which is subsequently used to encrypt the underlying system data. If an attacker damages the enclosure in an attempt to gain access, these delicate variations are altered, the key changes, and critical data cannot be recovered anymore. Despite PUFs provide real tamper-sensitive key storage, they are accompanied by some drawbacks, e.g., sensitivity to environmental conditions, aging, etc. which have to be tackled via additional means. Finally, I will discuss the current status of the development of PUF enclosures and outline the issues that have to be resolved to enable PUF-based security enclosures to secure future HSMs. (I will try to bring some real-world samples, so that there is the option to have a close look after the talk. However, I have to check this with my institute first.) About the presenter: I am currently doing my PhD at a research institute that focuses on embedded security. I am in the final phase of my dissertation about physical security enclosures, based on PUFs. This offers me a deep insight into the current development status of Physical Security Enclosures. In this talk, I want to share my experience with various solutions, from an analysis of a few up to the development of others. My goal is to discuss novel PUF-based solutions openly to raise awareness and to encourage more research into this interesting direction - from attacks up to countermeasures.

description: In many French cities (and beyond), mayors are pushing towards "safe Smart Cities", pushing for technology everywhere. Microphones, video-surveillance, automated drones, facial recognition, machine learning is the recipe of their fantasised secure city. This talk will introduce Technopolice, the new campaign from La Quadrature du Net, its goals, its tools, and the way we will make it happen. All over the French territory, the “Smart City” is slowly revealing its true colours: a complete and constant surveillance of the urban area for police purposes, based on partnerships between industrial companies such as Thalès or Engie and the cities themselves. Multiple cities are experimenting "smart" videosurveillance based on automated treatment of videos, in order to make face recognition or detecting behaviours deemed to be abnormal. Another city is teaming up with a start-up to deploy microphones and drones in the city. The idea is to detect so-called abnormal sounds to alert the police, which can then use video-surveillance to check if a patrol is needed or not. The city of Nice wants to have its own custom citizen reporting application. Marseille wants to use AI and Big Data to predict behaviours and to help in decision making. This is what they want our future to be: a huge automated surveillance system, with behaviour analysis, emotion recognition, pre-emption of threats, automation of the police, repression of any unwanted behaviour. This comes at a huge cost: instead of the polis , which means Democratic City, a place to stroll around, to meet and gather, we will have a dehumanised, unwanted place, a place to experiment the most advanced forms of social control: there is no such as surveilling just "to look", our behaviours are modified just by knowing we are being surveilled. Not to mention the financial and experimental cost of such an architecture. In this talk, I will detail the "Technopolice" campaign, its importance for every single human being willing to protect their freedom of movement and right to exist without being constantly subjected to surveillance. I'll explain the importance of decentralising such a campaign, and how we will try to federate the data and the organisations around this project.

The display is a proper piece of dual-use technology, serving both as hack material for fun and as a useful tool e.g. for taking notes during meetings. Come join us on a technology tour through the history of this fun piece of kit, starting with a look at the original hardware and software architecture and moving on through the many following software, hardware and mechanical hack generations in and around the display. The display has come quite far.

description: The Tor Project is building usable free software to fight surveillance and censorship across the globe. In this talk we'll give an update on what we have been up to in the past months, what happened in the wider Tor ecosystem, and what lies ahead of us. In the last year the Tor Project has been working hard on improving the software, building and training communities around the world as well as creating an anti-censorship team and roadmap that can push forward technologies to circumvent censorship. This talk will cover major milestones we achieved and will give an outline about what is lying ahead. In particular, we'll talk about the release of Tor Browser for Android and restructuring our anti-censorship efforts as well as working on next generation pluggable transports. Moreover, we'll explain our defense against website traffic fingerprinting attacks and plans for improving onion services and making them more usable (DDoS resistance, better user interfaces for authentication and dealing with errors). Finally, we'll shed some light on efforts to get Tor support directly embedded into other browsers, like Firefox and Brave, and educating users both by reorganizing the content on our website and extensive trainings throughout the world.

description: Eine Mischung aus einem Vortrag und einer Spiel- und Lernshow rund um die Datenschutz-Grundverordnung, die spielerisch Wissenswertes rund um Datenschutz und die Datenschutz-Grundverordnung vermittelt – anhand von tatsächlichen Beratungsanfragen und Datenpannen-Meldungen, die tagtäglich bei den Aufsichtsbehörden eingehen. Im Stil der Spielshow „Der Große Preis“ stehen Kandidaten Rede und Antwort zu skurrilen Fällen und heiß diskutierten Problemen rund um Datenschutz, technischen Maßnahmen und die DS-GVO. Bei Diskussionen über Datenschutz kommen technische Maßnahmen aus dem Bereich der IT-Sicherheit bisher oftmals viel zu kurz. Dabei können fehlende oder falsch implementierte Maßnahmen Sanktionen der Aufsichtsbehörden nach sich ziehen. Die große Datenschutz- und DSGVO-Show vermittelt auf spielerische Weise rechtliche, technische und praktische Hilfe rund um Datenschutz und die EU-Datenschutz-Grundverordnung. Welche Verschlüsselungs-Verfahren muss ein Datenverarbeiter verwenden, um kein Bußgeld zu riskieren? Erfüllt ein verschlüsselter ZIP-Anhang in einer E-Mail die Anforderungen der DS-GVO auf „Sicherheit der Verarbeitung“? Oder die „bisher ungeknackte Vollbitverschlüsselung“? Ist ein Messenger-Dienst „sicher“, wenn er Telefonnummern als SHA-256-Hash speichert? Muss ein Online-Shop wirklich alle Kunden informieren, wenn „ein Hacker“ erfolgreich „nur die E-Mail-Adressen der Kunden“ kopiert hat? Und was ist mit Google Analytics oder Facebook-Plugins auf Websites? Welche Rechte hat ein Betroffener gegenüber Datenkraken? Die Moderatoren sind der Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg Stefan Brink und zwei Referenten und berichten aus der praktischen Arbeit einer Aufsichtsbehörde. Vor und während dem eigentlichen Quiz geben sie eine kurze Einführung über häufige Datenpannen-Meldungen, rechtliche Grundlagen, Hinweise zu technischen Maßnahmen nach Artikel 32 DS-GVO und die oftmals schwierige Risikoabschätzung. Im Quiz selbst müssen die Kandidaten in ihren Antworten praktische Lösungsvorschläge für häufige technische und rechtliche Probleme vorschlagen, zum Beispiel welche technischen Maßnahmen bei bestimmten Datenpannen nach dem „Stand der Technik“ angebracht sind, ob man als Website-Betreiber denn nun Google Analytics nutzen darf oder wie man sich gegen rechtswidrige Datensammler wehrt. Dadurch können Teilnehmer wie Zuschauer die praktische Anwendung der DS-GVO spielerisch lernen.

description: Digitale Gewalt ist mehr als Hatespeech: Dazu gehören Doxing, Identitätsdiebstahl, Bildmanipulationen und deren Veröffentlichung, Spy Apps und noch mehr. Das meiste davon ist verboten, gilt aber nicht als 'Cybercrime'. Der Talk beschreibt, was dazu gehört, wer betroffen ist, was sich bei dem Thema seit den Doxing-Fällen im Januar getan hat und was nötig wäre, um langfristig etwas zu ändern. Auf die Frage, ob Digitale Gewalt gegen Frauen auch ‚Cybercrime‘ sei, antwortete die Bundesregierung Ende November 2018: „Da es sich bei digitaler Gewalt nicht um Straftaten handelt, die sich gegen das Internet, Datennetze, informationstechnische Systeme oder deren Daten richten, sind sie nicht dem Phänomen Cybercrime im engeren Sinne zuzuordnen.“ Wenige Wochen später drehte sich der Wind, als Anfang Januar bekannt wurde, dass 1000 Prominente gedoxt* worden waren, darunter viele Bundestagsabgeordnete. Mit diesem Fall wurde ein Vorgehen zum schwerwiegenden IT-Sicherheitsproblem, von dem vorher schon viele andere Menschen betroffen waren, ohne dass ein Hahn danach krähte. In diesem Talk wird im ersten Teil der aktuelle Stand der Erkenntnisse zu den verschiedenen Phänomen erläutert, die unter den Sammelbegriff Digitale Gewalt gegen Frauen fallen: Beleidigungen, Bedrohungen, Erpressung mit der Drohung, intime Bilder zu veröffentlichen oder das Veröffentlichen solcher Bilder - auch bekannt als ‚Revenge Porn‘ - , geheime Ton-/Bild-/Videoaufnahmen und die Weitergabe an Dritte, Online-Stalking, das Installieren von Spy-Apps, Identitätsdiebstahl und -missbrauch, Doxing, Manipulation und Veröffentlichung von Bildern bspw. zusammen mit der Wohnadresse usw. usf. Das alles ist verboten, aber aus verschiedenen Gründen ist es oft schwierig, sich dagegen zu wehren. Deswegen geht es im zweiten Teil darum, dass und wobei Betroffene zu wenig Unterstützung bekommen: praktisch, juristisch, durch Polizei und Politik. Das beginnt oft bei der Frage der Zuständigkeit. Unter Cybercrime wird in der Regel kriminelles Verhalten gegenüber Geräten, Unternehmen oder Infrastrukturen verstanden, jedenfalls nach Auffassung deutscher Innenpolitiker. Dazu kommen Fälle, bei denen es ums Geld geht und natürlich auch Kinderpornographie. Innenminister Seehofer hat im Januar verkündet, dass das neue IT-Sicherheitsgesetz die Probleme lösen soll, die zu den Doxingfällen des „Adventskalenders“ geführt haben. Auf dem Tisch liegen Vorschläge für mehr Überwachung, weniger Verschlüsselung und mehr Geld für die Sicherheitsbehörden. Immerhin: Das BSI soll sich mehr um Verbraucherschutz kümmern. So wie es aussieht, ist die digitale Seite der häuslichen Gewalt aber wieder nicht dabei – dafür ist ja das Familien- und Frauenministerium zuständig. Betroffene von Doxing, Revenge Porn, ferngesteuerten ‚Smart Devices‘ oder Spy Apps haben es meist schwer, kompetente Ansprechpartner*innen bei Polizei und Justiz zu finden. Es gibt auch kaum Beratungsstellen für diese Fälle, obwohl die Folgen manchmal schwerwiegend sind. Deswegen gibt es im dritten Teil konkrete Tips für Betroffene und Hinweise, wo derzeit Lücken bestehen und Vorschläge, wie die geschlossen werden können Vielleicht - hoffentlich - ergibt sich im Anschluss an den Talk die Gelegenheit darüber zu sprechen, wie in manchem Fällen ganz praktisch Abhilfe geschaffen werden kann. *Doxing bezeichnet das Veröffentlichen privater Daten oder Informationen (= Dokumente, ‚Docs‘) im Netz

description: Ein automatisiertes Gebäude ist schön, komfortabel und praktisch. Doch das wäre nicht Thema für einen Vortrag beim CCCamp, wenn es nicht einige gravierende Schwachstellen in den Bussystemen gäbe. Der Vortrag bietet eine Einführung in die Funktionalität von vernetzten Gebäuden am Beispiel des KNX Standards. Ohne dass ihr großes Vorwissen benötigt, berichte ich euch von Sicherheitsproblemen und möglichen Lösungsansätzen zur nachträglichen Steigerung der Sicherheit solcher Gebäudeautomatisierungssysteme. Feldbusse wie KNX werden in modernen Gebäuden eingesetzt, um typische Vorteile der Gebäudeautomation zu erzielen. Man verspricht sich Komfortgewinn, Kosteneinsparungen und Flexibilität. Klassische Schutzziele wurden beim Design dieser Bussysteme hintenangestellt und IT-Sicherheit so sträflich missachtet. Funktionalitäten wie Verschlüsselung oder Authentifikation der Kommunikationsteilnehmer sucht man bisweilen vergeblich. Sind die Gebäude erst einmal gebaut, wird die installierte Infrastruktur über Jahrzehnte betrieben. Das Licht des Kollegen im Nachbarbüro zu schalten ist ebenso leicht, wie das Steuern einer an den Feldbus angebundenen Heizung. Was im Büro noch verhältnismäßig harmlos erscheint, wird bedrohlich, wenn man bedenkt, dass auch Kraftwerke und andere kritische Infrastrukturen ähnliche Systeme nutzen. Nach einer Einführung in den KNX Bus geht der Vortrag auf Schwachstellen und deren mögliche Folgen in automatisierten Gebäuden ein. Es wird gezeigt, dass sich aus scheinbar harmlosen Sensoraktivitätsdaten bereits intime, personenbezogene Informationen herausarbeiten lassen. Um die Sicherheit bereits installierter, langlebiger Gebäudeinfrastrukturen dennoch zu erhöhen, werden bereits bekannte Verfahren aus der IP-Welt auf Feldbusse übertragen. Netzwerksegmentierung, IDS und Filterung sind erste Ansätze, auf die der Vortrag eingeht. Es werden deren Möglichkeiten und Grenzen beschrieben. Darüber hinaus wird ein entwickelter Testdatensatz zur Evaluierung solcher und anderer Ansätze vorgestellt.

description: The world is entering a new era of instability. The climate crisis will put great pressure on the (relatively) peaceful balance of world politics. But the field of open source intelligence (OSINT) provides us with a new and unique way to map, study and predict these flashpoints. This talk will look at several technical approaches for using these techniques and include several example studies. Intelligence agencies, NGOs, business groups, and insurance companies all agree that the worsening climate crisis will fuel war and global crises. Some go further, saying that societal collapse is all but inevitable. Whatever your view on this is, it is difficult to see our current paradigm of general peace continuing into the next few decades. But as this crisis worsens, modern technology has also gifted us with new tools to monitor, analyse and predict flashpoints. The emerging field of Open Source Intelligence (OSINT) is one such tool. OSINT uses publically available data (such as social media posts, video footage, satellite imagery, public databases and remote sensing) as the basis for in-depth investigations. This talk will look at the ways in which these techniques can be usefully applied, both journalistically and analytically, within the context of the aforementioned crisis. Specifically, it will look at two examples of how OSINT can be used to analyse past events over the last year, and one concept for predicting a future event.

description: The beautifully complex structures often found in Nature arise from the collective interaction of huge numbers of particles moving under very simple forces. Starting from this fact, I will present how we can encode simple physical properties into large scale networks in a way that mimics a physical system and leads to elegant structures in 2d or 3d space. After introducing some basic concepts, a large part of the talk will consist of animated demonstrations of network evolution towards a final layout. The talk is aimed at scientists and curious non-scientists alike. Large networks (graphs) appear in many types of human activity: computer, social, transportation, biological, and other networks that model the various connections and interactions in a system. Networks are often depicted visually as sets of points on a plane connected by lines - at large scales however, this image becomes too difficult to interpret due to high density of points and/or too many line crossings. So it is essential to determine an ideal placement of the network's parts in order to reveal its structure in the most clear and informative way. The laws of physics inherently contain dynamics capable of creating aesthetically appealing arrangements of high complexity, as can be seen in snowflakes, soap bubbles, crystals, or molecules in 3d space. By encoding physical qualities and dynamics in a network, we can leverage the laws of motion and the corresponding forces to let them shape the network. As the network is now acting like a physical system, it evolves towards a configuration of minimum energy and reaches a final state that exposes the symmetries, connected parts, and other features, in analogy to the wonderfully complex structures found in Nature.

Unfortunately, they don't provide a comprehensive view of the Internet because you can't access the raw data. Consequently, you have to scan the Internet yourself. Anyone can perform a one-shot scan via Mass-Scan & Co. However, how to build an infrastructure for regular Internet scans that is not blocked after a short time by Intrussion Detection Systems and Spam/Blacklists is not easy. First we will talk about the right scan setup, infrastructure, scan strategies, and data enrichment. We will then take a look at the data and gain common and interesting insights into the structure of the Internet.

Unfortunately, they don't provide a comprehensive view of the Internet because you can't access the raw data. Consequently, you have to scan the Internet yourself. Anyone can perform a one-shot scan via Mass-Scan & Co. However, how to build an infrastructure for regular Internet scans that is not blocked after a short time by Intrussion Detection System and Spam/Blacklists is not easy. The following questions must be answered: Which scanning algorithms are used (centralized, distributed, BGP prefix hit lists)? How could you reduce scan traffic? How do I process the data in the long term (up to 600GB / scan)? With which further data do I enrich the scans for further analyses (BGP prefixes, Inetnum objects) ? How do I build the right server without a bottleneck and how do I connect it to the internet (rent a server or become a RIPE-Member/ your own ISP with a /22 IPv4 /32 IPv6 Block)? In the first half of the talk we will deal with these questions. In the second half of the lecture we will discuss real scan data. We will concentrate on the analysis of the network topology and distribution of BGP prefixes, whois blocks and network services of well-known autonomous systems on the Internet. As a further example, we will look at the network structure of a large well-known German hoster, which gives us a good overview of its internal organization of data centers and other services. Finally, we will look at some data and analysis from a security perspective.

description: Remember the good old fun sport, where people bought random hard drives from ebay and did forensics on them? Did you know you can do the same thing with used IoT devices too? Most end-users have no idea what kind of information their devices are storing and how to securely clean their devices (if that even is possible). Lets explore together what the risks are and how we can extract that data. Many IoT devices collect a lot of data and log files. Of course, most of this data is sent to the Cloud. However, often this data is also stored locally on the device and never deleted in the lifetime of those devices, not even on a factory reset (in contrast to Smart Phones nowadays). This might surprise many people, and especially end users might not be aware of that. Due to the design of IoT devices, there is usually no real way, like for notebooks or PCs, for end users to clean the devices before they sell them on eBay or discard them. The devices may hold sensitive information like Wi-Fi credentials, nearby access points, cloud communication log files, maps, or audio samples. In this talk I will show some examples of interesting IoT devices from various vendors and how to extract the corresponding information. We will use software methods (rooting) and hardware methods (flash dumping). Using this information, I will show how I am able to find the original owner of the device. Also I discuss various challenges and tricks of the methods, and how to prevent this kind of data leakage for yourself.

description: Mobiltelefone hinterlassen aufgrund ihrer Funkaktivität in der Umgebung vielfältige Spuren, die von entsprechendem passiven Equipment aufgespürt und verarbeitet werden kann. Doch um tiefer in die Kommunikation zu schauen, braucht es aktive Netzwerkomponenten – sogenannte IMSI-Catcher oder Stingrays, die den Kontakt zu ihren Zielen direkt suchen und Informationen austauschen. Doch wenn sich solche hinterhältigen Basisstationen auf die Lauer legen, müssen sie sich zu Erkennen geben – und können erkannt werden. Der Vortrag erörtert technische Hintergründe, verräterische Anzeichen eines Angriffs und was Netzwerkbetreiber und Nutzer dagegen tun können. Oshie arbeitet seit 4 Jahren an Heuristiken zur Erkennung und Werkzeugen zur Visualisierung von rogue base stations. Der Vortrag gibt einen Überblick wie IMSI Catcher arbeiten, was sie heutzutage leisten und wie sie dabei beobachtet werden können. Hierbei werden Sicherheitsfeatures der unterschiedlichen Netzgenerationen, von 2g bis 4g, betrachtet und was das konkret für den Einsatz von IMSI Catchern bedeutet.

description: The little known International Health Regulations are Earth's last defence line against world-wide health risks. I discuss how they would perform during a Zombie Apocalypse. The International Health Regulations (IHR) are a piece of legally binding, international law that (theoretically) all countries have to adhere to. After the catastrophic 2003 SARS outbreaks, unlikely partners such as the USA and Iran, together with 192 other member states of the World Health Organisation, agreed upon these rules that entered into force in 2007. This set of rules aims to prevent international spread of health risks (usually communicable diseases) while balancing international travel and, of course, trade. I will use the popular Zombie Apocalypse metaphor to illustrate the various prevention mechanisms of the IHR and how they were (and will be) circumvented by past and future epidemics.

description: This case study of NoScript’s UX redesign showcases tried and true design principles that make security tools usable to a wider range of audiences. Open source security tools are often associated with customizability and transparency: users are given many options (configurations, self-hosting), and system states are more often than not visible to users (detailed connection info, logs). Sometimes, that means bulky user interfaces and technical language, making an otherwise useful and recommended tool less usable for non-technical audiences. This presents a distinct design challenge: is it possible to build tools that are more usable without compromising on customizability and transparency? In this talk, we will present some UX design principles based on our work with NoScript, a browser extension that allows users to fine-tune their script blocking in Firefox and Chrome/Chromium. We will focus on 1) understanding the value you add for your users, 2) choosing sensible default options, and 3) updating interface language for a wider audience. In the course of that, we will also present our process of human-centered design for improving security tools. (Outlined here: https://simplysecure.org/what-we-do/usable-security-audit/ )

description: Sonnenenergie deckt heute erst etwas über 2% des weltweiten Energiebedarfs durch Umwandlung von Sonnenlicht in elektrische Energie. Eine der Möglichkeiten, um diese zu speichern, ist die Elektrolyse von Wasser, um Wasserstoff zu erhalten. Was aber wäre, wenn man Wasserstoff direkt gewinnen könnte? Eine schnelle Übersicht über Sonnenlicht, das Prinzip hinter Photovoltaischen Solarzeiien, und wie photoelektrochemische Zellen, die flüssiges Wasser in seine Bestandteile Wasserstoff und Sauerstoff spalten können, beide Prozesse miteinander kombinieren können. Die von uns Menschen verantworteten CO2-Emissionen müssen reduziert werden, aber wie? Die Erzeugung von elektrischer Energie aus Sonnenlicht wird mit großer Sicherheit einen signifikanten Beitrag zur Deckung des weltweiten Energiebedarfs liefern. Zuerst sehen wir uns das Spektrum der Sonne an, und wie viel dieser Energie wo auf der Erde ankommt. Wenn dieses Licht auf Atome trifft, wie die Siliziumatome in einer Solarzelle, kann es diese in einen energiereicheren Zustand anregen, aber nur ein Teil des Sonnenlichts hat genug Energie, um diese Anregung zu erreichen. Was für Konsequenzen hat das für die Effizienz von Photovoltaik-Zellen? Jeder kennt die blau-schillernde Silizium Photovoltaikzelle, die Größen von wenigen Quadratzentimeter in einem Taschenrechner über Installationen auf Hausdächern mit einigen Kilowatt bis zu Solarparks, die mehrere Megawatt Spitzenleistung abgeben können. Solarenergie ist vom Tag-Nacht-Zyklus der Erde und von der Jahreszeit abhängig. Um die Energieversorgung auch z.B. im Winter bei geringerer Sonnenintensität decken zu können, muss diese längerfristig gespeichert werden. Verschiedene Strategien sind denkbar, eine davon die Umwandlung in chemische Energie in Form von Wasserstoff durch Elektrolyse von Wasser. Beide Technologien bringen Umwandlungsverluste mit sich und erfordern teilweise teure Metalle und viel Energie bei der Herstellung. Aber es gibt eine Klasse an Halbleiter-Materialien, die, wenn man sie in Wasser eintaucht und mit Sonnenlicht bestrahlt, die Lichtenergie direkt auf das Wasser übertragen, und es in Wasserstoff und Sauerstoff spalten können. Man umgeht die Kopplung von Photovoltaik und Elektrolyse. Viele dieser halbleitenden Materialien sind mit weit weniger Energieaufwand herzustellen als Silizium. Besondere Aufmerksamkeit ist auf häufig vorkommende und damit gut verfügbare Metalle gerichtet. Eisenoxid - Rost, oder Titandioxid - das Pigent aus weißer Wandfarbe, sind zwei Beispiele, die jeder kennt, ihre Superpower aber sehr warscheinlich nicht. Noch sind die Wirkungsgrade gering und marktreife Lösungen noch nicht absehbar. Wenn der Ansatz allerdings erfolgreich ist, könnte dies ein Durchbruch für unsere Energieerzeugung sein, und nebenbei einen Teil des Problems lösen, Energie zu speichern und zu transportieren.

description: Removing the barriers to making network independent mobile communications. In this talk I will discuss our thinking and progress towards making personal mobile communications devices, i.e., things that you use like a smart-phone, but that are fully under the control of the owner. While this has been done before, we have been focusing on how to make this much easier to do, so that individuals or small teams can create their own custom devices, with whatever features, inclusions and physical form they like, without huge time or cost requirements. This makes it possible to solve security and privacy problems, and also problems like creating custom devices for people living with disability, so that they can have a device that works for them and with their abilities and needs. I will discuss our work-in-progress in this area, the MEGAphone, which is not only a mobile phone, but also includes UHF packet radio and a modular expansion scheme, that can allow allow the incorporation of satellite and other communications. It is also backwards compatible with the Commodore 64, so can already play loads of privacy-preserving games, and has its own open-source slide presentation software that we hope to use to deliver the talk. Private UHF and VHF radio communications is a complex space, in terms of regulation, which we have some experience in due to the Serval Project, which has informed our design of the MEGAphone. I will thus discuss issues such as using "license free" bands around the world, as well as options for using either licensed spectrum or existing legacy public spectrum allocations, such as Citizen Band (CB) radio. As the MEGAphone platform is FPGA based, it is quite possible to implement software defined radio solutions to allow flexible and low-cost access to such spectrum.

description: Ships have long been required to carry nautical charts and nautical publications to plan and display the ship's route for the intended voyage and to plot and monitor positions throughout the voyage. Today we have complex electronical navigational charts and many of them are freely distributed and are constantly updated. An electronic navigational chart or ENC (IENC for Inland waterways) is an official database created by a national hydrographic office for use with an Electronic Chart Display and Information System (ECDIS). The automatic identification system (AIS) is an automatic tracking system that uses transponders on ships and is used by vessel traffic services (VTS). Even with the advent of high accuray DGPS and AIS, RADAR will continue to be a primary aid to navigation and collision avoidance. During the presentation we will exemplify some usecases that integrate ENC, AIS and RADAR data in various software applications, both web and desktop, onboard for navigation or vessel/infrastructure for coastal monitoring systems. The presentation will cover an aids for navigation monitoring system, a vessel traffic management system and an 3D environment with real time data for validation of inland waterway signs and markings.

description: We started working on BIM (Building Information Model) and GIS integration in 2016. At that time, as one of the results of EU funded research project [DIMMER](http://www.drawingtothefuture.polito.it/projects/dimmer/), we [linked](http://2016.foss4g.org/talks.html#140) the simplified representations exported from BIM to the urban environments in Turin, Italy and Manchester, UK. Since 2016, our work on GIS and BIM integration has steadily [progressed](https://webthesis.biblio.polito.it/6408/). Nowadays, the Municipality of Turin uses the successful integration of GIS and BIM objects for internal facility management of thirty public owned buildings in Turin. Adopting the [3D Tiles](https://github.com/AnalyticalGraphicsInc/3d-tiles) OGC standard, we stream and render online the full BIM and photogrammetric reconstruction of Turin buildings and monuments. Also, using open source tools and open data, we extend the value of digital BIM through visualisation and integration with available cartography. This allows us to fully benefit of BIM potentiality in terms of data and object management. Furthermore, we display our maps and models using open source virtual globes, an easily accessible environment.

description: Open source satellite imagery becomes increasingly important in many areas of research and business. In the case of agriculture, it is being used to assess land use, support subsidies, and to help farmers to manage their land more efficiently. Many of these applications require regular revisits to best catch temporal the variety that defines many land uses. Cloud cover can be a serious issue, often obscuring the majority of images acquired from passive sensors. Filtering an area of interest for cloud free images, can be labour intensive or lead to loss of valuable input data. Here we introduce a Python tool developed using open-source packages that will assess user defined areas of interest against supplied cloud masks for three satellite platforms: ESA’s Sentinel-2 (Level 1C products), NASA’s Landsat-8 (Level 1C and SR products) and the joint CNES and ISA platform Venµs. We present a case study from County Meath, Ireland to assess the number of cloud free Sentinel-2 images identified for fields surveyed in the EU Land Use/Cover Area Frame Survey (LUCAS) and compare it to the number of images that would have been obtained by threshold filtering images.

A test suite for new OGC standard WFS 3.0, which is currently a candidate standard (status of April 2019), was developed as part of OGC Testbed 14 initiative. As this standard uses completely different concepts in comparison to, for example, WFS 2.0, several conceptional questions had to be discussed and solved during implementation of test suite. This talk presents how the new OGC standard WFS 3.0 can be validated with TEAM Engine. The process of creating a new test suite as part of OGC Testbed 14 initiative is highlighted. This includes a short introduction of WFS 3.0 standard itself. Further, current developments in TEAM Engine project are presented and an outlook is given.

description: This presentation will provide the attendee with an introduction to data processing in GeoServer by means of WPS, rendering transformations and SQL views, describing real applications and how these facilities were used in them. We'll start with the basic WPS capabilities, showing how to build processing request based on existing processes and how to build new processes leveraging scripting languages, and introducing unique GeoServer integration features, showing how processing can seamlessly integrate directly in the GeoServer data sources and complement existing services. Moreover, we will show how to integrate on the fly processing in WMS requests, achieving high performance data displays without having to pre-process the data in advance, and allowing the caller to interactively choose processing parameters. While the above shows how to make GeoServer perform the work, the processing abilities of spatial databases should not be forgotten, so we will show how certain classes of processing can be achieved directly in the database. At the end the attendee will be able to easily issue WPS requests both for Vectors and Rasters to GeoServer through the WPS Demo Builder, enrich SLDs with on-the-fly rendering transformations.

description: In this talk, we will give an overview of the recent works that have occurred in the PROJ, libgeotiff and GDAL libraries regarding Coordinate Reference Systems (CRS). Those improvements have mostly taken place in the venerable PROJ library that has evolved over the last 30 years from handling “only” more than hundred of cartographic projections to becoming a full-fledged library for CRS management and transformations. PROJ 6 now supports OGC and ISO standards regarding object modeling (ISO-19111 / OGC Abstract topic 2), and their Well-Known Text representation (OGC WKT1, WKT2:2015 and latest WKT2:2018). A sqlite3-based database embeds the definitions coming from various authorities: EPSG, IGN-France and the ESRI projection engine. PROJ can now compute optimal and more accurate transformations between two CRS without necessarily using the ill-defined WGS84 pivot (“late-binding”), and support new CRS and transformations. We will discuss the the adoption status of PROJ 6 by the rest of the OSGeo stack and present quickly how to migrate to this new version.

description: Geographic flow visualization (gFlowiz) is an interdisciplinary project dedicated to flows and networks in the geoweb. It is led by a team of French researchers and engineers in Geography, Cartography and Computer Science from both IFSTTAR and CNRS. gFlowiz follows the new paradigm of « visualization mapping » (MacEachren, 2004) not present in current geoweb applications. All types of flows, movements and traffic in a geographical space, at several scales, are involved (migrations, freight, transportation, etc). Required semiological, aesthetical and design elements offered by currently web-based graphic visualization libraries are also considered. Its main goal is to build a simple application combining two pillars of scientific graphical representation: flow data processing and (geo)graphical modalities visualization. A state of the art on current issues of flows and movement analysis on the geoweb has been produced through the compilation of around 70 applications in a thematic dashboard, and a 200 respondants survey on flow map usages and needs has been realized.

description: The availability of the growing volume of environmental data from the Sentinel satellites represents a unique opportunity for the operational usage of Earth Observation (EO) for wetland inventorying, assessment and monitoring on global scale. However, it also poses major challenges in terms of data access and exploitation to achieve its full potential. GlobWetland Africa (GWA) Toolbox is an outcome of an initiative of the European Space Agency launched to facilitate the exploitation of satellite observations for the conservation, wise-use and effective management of wetlands in Africa. It is a fully free and open-source software toolbox that seamlessly combines algorithms from a number of EO and GIS tools like SNAP, QGIS, OrfeoToolbox, GRASS GIS, TauDEM together with customised Python and R scripts (e.g. for hydrological modelling) into one GUI based on QGIS. This is achieved by relying heavily on the QGIS Processing Toolbox. The algorithms are then combined into workflows, which guide less experienced users through step-by-step process of EO data analysis for wetland delineation, wetland habitat mapping, monitoring of inundation regimes and water quality as well as for mangrove mapping and river basin hydrology assessments.

description: In close collaboration with UNICEF Uganda and GeoGecko, KCCA spearheaded the development of an online open source portal to provide a visual presentation of key social services available in Kampala. The tool is built on the backbone of four pillars aimed at (i) identifying key partners’ operations and the nature of their engagement in Kampala, (ii) mapping infrastructure points designed to deliver predetermined services (e.g. schools), (iii) summarizing parish level specific socio-economic profiles, and ultimately (iv) offer insight into the lives of young Ugandan adolescent girls accessing such service in Uganda’s capital city. The tool is built with Open Source tools and can therefore easily be adopted to other projects, regions and be implemented in another context. During this presentation we will (i) walk through the portal and explain how it is created, (ii) describe how it is currently used, and most importantly (iii) discuss how it can be improved and adapted to other sectors at scale.

description: Initially called GRaaS (GRASS as a Service), actinia has been developed to exploit GRASS GIS functionality via HTTPS REST API. GRASS locations, mapsets, vector and raster data as well as spatio-temporal data are available as resources to allow their management and visualization. With the existing (e.g. Landsat) and also recently emerging (Copernicus Sentinel) big geodata pools which are growing day by day, it is designed to follow the purpose of bringing algorithm to cloud geodata. It helps to prepare, analyse and provide a large amount of geoinformation without the need to have know-how of the data, of analysis, appropriate software (for automatisation) or scalable hardware resources. Some of the features are persistent and ephemeral processing, user management to limit e.g. pixels, processes and duration of calculations as well as logging of API calls and used resources by each user. Another advantage is its easy deployment with docker. When deployed in a cloud based environment with OpenShift or docker-swarm, the integrated load balancer handles a cluster automatically. Following the spirit of free and open software, we are proud to have emerged as an OSGeo community project and look forward to enlarge the actinia community.

description: Deutsche Telekom AG (DTAG) revolutionises the planning process of fibre networks (FTTH) to * increase number of connected households and industries dramatically, and * shorten the time to market in general. For this goal DTAG, advanced geoprocessing algorithms including artificial intelligence (AI) automate the conversion of surface information into cost optimised potential trenches used in the fibre build process. The surface information is gathered by terrestrial laser scanners and photos as well as extracted through a complex analysis from aerial orthophotos. This surface information then is used in conjunction with other (open) data as an input for the provisioning of potential trenches needed for FTTH. The processing of these orthophotos as well as the calculation of trenches are handled by the open source actinia cloud geoprocessing engine. Actinia is a new OSGeo community project, offering a REST API to GRASS GIS. The actinia processes are scaled and implemented as a service in the Open Telekom Cloud. In this talk, we present the handling of large and complex input data in the FTTH-process. Focus is on the usage of actinia, and how actinia supports a core process of the largest German telecommunication provider.

description: The Copernicus Global Land Service (CGLS) aims to provide yearly-updated land cover maps, including land cover fractions (i.e. the fraction of each land cover class within each pixel). It makes use of FOSS software (Python, R, GDAL) for all data processing steps. Our work in the project focuses on two aspects: land cover fraction mapping at the continental level (Africa) and yearly map updating. For land cover fraction mapping, to select the most appropriate method, a number of machine learning algorithms were run on over 300 covariates: Proba-V image time series (100m, 4 bands), DEM, soil and climate properties. Random Forest performed the best with RMSE=16.6, MAE=9.2, and 68±4% overall accuracy. To generate yearly map updates, we investigated different vegetation indices and break detection methods, as well as their scalability to big data (MODIS time series, 2009-2019). All change detection methods tended to overestimate change. Proba-V Mission Exploitation Platform Spark cluster was used to run chunked jobs in parallel. In the future, CGLS aims to move to Sentinel-1+2 for land cover classification and Landsat 5+7+8 for change detection for higher spatial and spectral resolution, but that makes big data challenges even bigger.

description: The sheer amount of statistics collected as the world entered the age of Big Data transformed computers from simple tools for processing data into complex machines able to present the results of this processing as compelling visuals with little to no human input. And when it comes to presenting the evolution of phenomena that vary in space and time, there is no better solution than a map. As part of a project involving a major institutional client, we developed a FOSSGIS-based custom spatial visualisation widget for use with Microsoft’s PowerBi. Integrating with an environment that includes a plethora of graphical representations for data, the developed widget, built on top of OpenLayers, provides a novel view of data with spatial characteristics. Unlike the default map widgets, it allows the use of custom, time-enabled geometries, as well as custom basemaps, consumed using open standards (GeoJSON, WMS), custom projections (with Proj4js), feature zoom across the International Date Line and complex visualisation using charts on top of choropleth maps. We thus show the advantages of using open-source GIS technology on top of proprietary frameworks, providing advanced, project-specific features supported by a wide community.

description: Tokyo Metropolis publishes a lot of data, and holds an application contest using that data every year. The 2017 contest had the challenge of "developing a tool that would allow everyone to find the perfect toilet for them on the go". I applied for the contest on this subject. There is a chat tool named LINE in Asia,many people use it. We can respond to user input programmatically by creating an auto-answer program called Bot and linking it to this chat tool. I thought that I could search for toilets from LINE if I made a search bot. Some Japanese public toilets are barrier-free.Some toilets have a table to replace baby diapers. Some toilets have facilities for people who wear stoma to clean it. The toilet data published by the Tokyo Metropolitan Government contains information on the position of the toilet and the equipment attached to the toilet. The chat tool LINE is often used using a smartphone. If you use a smartphone, you can search public toilet in Tokyo. So I made a prototype to search the toilet using location and facility information as LINE input program. I used FOSS4G to handle location information in creating this program. At this conference, I would like to explain this development.

description: Roads are essential in our day to day activities. In developing countries especially in Africa, the road sub-sector accounts for over 80% of the total passenger traffic and 76% of freight leaving a small proportion to water, rail and air transport. For this reason, they need to be in their best condition to increase the productivity of the region. The maintenance of the road network in Kenya is handled by five different agencies all coordinated by the government. Ideally, the process involved requires the collection of data for selection and prioritization purposes but this is rarely done due to the associated costs. This research aims at providing decision support based on real-time data from different sources including Twitter reports in addition to the data received from the different mandated agencies ensuring a data-driven decision making process. This will further offer comprehensive condition-based decision support that goes beyond the time-based nature of the current process.

description: Colombia is facing a huge challenge to formalize land tenure in an efficient, massive and decentralized manner. The Swiss cooperation provides all different actors with a common conceptual and technical framework. On the one hand, a Colombian profile [1] of the LADM (ISO:19152) was built, constituting the core of a Spatial Data Infrastructure for Land Administration (IDE-AT). On the other hand, the INTERLIS language [2] guarantees interoperability for data formats and systems and is the basis of a free software ecosystem around the project: QField [3] offers automatically generated forms to capture both geographic and alphanumeric data, as well as their associated documents. In the office, operators use a QGIS plugin called “LADM_COL Assistant” [4] to migrate and structure field data into a LADM-COL database. The same tool is employed by cadastral authorities to receive, validate (both topologically and logically), review and integrate the data incorporating changes into official systems. Finally, the new data is disposed in the IDE-AT to all actors of land administration. The project not only develops new software, but also contributes code to base projects such as ili2db [5], QGIS Model Baker [6] and QGIS [7] itself.

description: In the past, desktop GIS were necessary to handle complex spatial business decisions. This lead to problems with data management, model updates and an increased cost to the organisation in hardware and (often) software maintenance. As organisations move to more cloud based solutions and provide staff with thinner client machines (chrome books etc.) it becomes harder for staff to manage more complex geospatial problems. The Open Geospatial Consortium (OGC) developed the web processing service (WPS) standard in 2005. It provides rules for standardizing how inputs and outputs (requests and responses) for geospatial processing services are made. The standard also defines how a client can request the execution of a process, and how the output from the process is handled. It defines an interface that facilitates the publishing of geospatial processes and clients’ discovery of and binding to those processes. This talk will present case studies of how Astun Technology has used the OGC WPS standard, as implemented by GeoServer, to allow users of web based mapping applications to carry out advanced spatial operations and allowed them to implement complex business logic without the need for specialised hardware or software.

description: More open pointcloud data is released every year and with it there is an increasing request for automatically generated large scale digital maquettes that can be used in city-planning, environmental modelling and 3D data-analysis. We will show how we use a pipeline of OS software that goes from pointclouds and cadastral data to a full scale 3D maquette of your country. Processing happens mostly in postgres and takes typically a couple of minutes per square km. Included in the talk is: * introduction of some python-scripts for pointcloud-processing * adoption of procedural language in postgres * advanced use of postgis (voronoi, sfcgal etc) * generating 3D tiles * styling a maquette in cesium The presentation will be fast paced and includes a range of technical details but should be understandable for the average person. It includes code examples and live demo's. In the end you will have an understanding of available software (both new and existing), do's and don'ts in generating 3D data with OSS and contemplations on how to use a digital 3D maquette.

description: The patterns of recent disasters in Korea such as typhoons, mountain fires and earthquakes are becoming increasingly complex and extensive. At the same time, there have been repeated problems with the government's ability of disaster response system. It is important to look at the disaster from a unified perspective in order to reduce the damage that will occur from the disaster and promote recovery. In addition, the integration of the disaster management agency's situation-specific work process and information is one of the important parts for rapid response to the situation and reduction of damages. However, as most of the information used to response with disasters is temporarily used, there is a lack of periodic updates or management systems. Therefore, the continuation and clarity of information up to the recovery stage are unclear, and no definite recovery is supported for the disaster affected areas. In this study, the implementation manual and history of the situation response to major national disasters in Korea are analyzed to identify problems in response to existing disaster situations.

description: Funded be the European Commission as a H2020 project, openEO aims for a new web service standard to process Earth Observation data cubes. At its core, openEO provides an http application programming interface (API) that defines how users can discover Earth observation data cubes and process them on compliant cloud back-ends. The back-ends run their own API instance, translating the http requests to their environment. The front end API implementation can serve different languages (R, Python, Javascript) on the client side. The openEO project has foreseen that APIs are implemented with an open source license (Apache 2.0). A number of back-ends are already available that are compatible with this suggested openEO standard. For instance, within the Joint Research Centre (JRC) of the European Commission, an API implemented in Python is being developed that can discover and process geospatial data collections available in the JRC Earth Observation Data and Processing Platform (JEODPP). For the back-end, an in-house library is being developed under the European Union Public Licence (EUPL). In this presentation, we will highlight the openEO concepts and focus in particular on the JRC back-end implementation details.

description: ECMWF is an operational centre, producing global numerical weather predictions. ECMWF also operates many services for the EU Copernicus programme . ecCharts is a suite of web based services to visualise and explore ECMWF real-time forecast. The service offers a Web Map Service (WMS) as well as an interactive client application which provides forecast data for meteorological community including Copernicus services. Recent development work involved the replacement of the client application with OpenLayers and implementing a caching system with MapProxy. This posed many challenges due to size and frequent updates of the data, combined with the challenges of offering a fast and smooth user experience. The work also resulted in contributions to open source projects, like OpenLayers, which will benefit the wider user community. This talk presents the benefits of moving to open source community software,the architecture of the updated system and on the challenges and the solutions that are taken when dealing with big and dynamic data sets both at the frontend and at the backend services.

A brand-new world comprising the build up of a major SDI, lots of geodata and heavy geoprocessing is needed to substitute previous manual tasks and to sustain the goals. Think about a project, that will be developed by +10 companies, each with its own frameworks, procedures and deployment workflows. To succeed, you'll need more than confidence in the team. This is also because of other complicating factors like IT security, large data pipelines or ever-changing IT infrastructure. This is where DevOps and AGILE practices came to the rescue. It gave a structure and a common understanding of the workflows to every project member, as well provided enough automation and flexibility to adjust to the constant changes the project undergone. In this talk, we’ll present the key challenges and how DTAG and the team of the FTTH-Factory successfully implements agile and DevOps workflows for the project.

description: How to compute the two closest points between two administrative units in a city and how this differs from distance computation? What happens when some points are on opposite/antipodal sides of the globe? How can one create equidistant points along a trajectory modelled by line segments? We discuss solutions to those questions highlighting some of the latest developments in Boost Geometry, the library that is currently being used to provide GIS support to MySQL. The implemented algorithms are parameterized by strategies that control the accuracy-efficiency trade-off. The proposed solutions work for 3 different coordinate systems (namely, cartesian, spherical and ellipsoidal) each of which comes with its own advantages and limitations. Those are illustrated and supported by benchmarks. The presentation is example driven thus emphasizing on the user perspective while glancing at the algorithmic and implementation aspects of the library.

description: To be INSPIRE compliant is a requirement implied by the European Union. From an administrative view, the desire for standardized data for aggregation is very comprehensible. Producing and delivering data that complies with these requirements comes with a great set of challenges but is key to bring any such system to success. In Switzerland the same requirements exist for standardization and aggregation. To reach this goal, a system with the name INTERLIS is developed for more than two decades already. During this time, a rich ecosystem has started to exist which builds bridges from a formal model all the way to the user interface with tools like ili2db and QGIS Model Baker. All of this built with open source tools that are accessible for anyone. This talk will give an overview over a state of the art toolchain that helps data providers to produce high quality data which can keep up with national and international data requirements.

description: Identifying the correct location of channel heads remains a challenging aspect in hydrogeomorphic analysis. Though field mapping is a reliable method, this may become infeasible for large basins. High resolution remote sensing data provides another way to predict channel heads. Existing literatures have suggested use of digital elevation models (DEM) to extract channel heads by applying an area or slope-area thresholding method. However, channel initiation process is more complex and depends on other factors like topographic curvature, land use land cover etc. In this study, we have used machine learning models to extract channel heads from freely available 1 arc second SRTM DEM data for a basin in the Lesser Himalaya. We have used upstream area, local slope and local curvature as features in our models. Actual channel heads were digitized manually from high-resolution (1-2 m) IKONOS imagery available on Google Earth. Decision tree model generated the best results with a F1-score of 0.45 and correctly predicted around 78% of the channel heads from the test set along with a high number of false positives. Future work will be applying this method on available high-resolution Lidar-derived DEM, with more field-mapped channel heads.
