description: PyWPS is an open source, light-weight, Python based, implementation of the OGC Web Processing Service (WPS) standard. It provides users with a relatively seamless environment where to code geo-spatial functions and models that are readily exposed to the Internet through the WWW. Initially started in 2006, PyWPS has been completely re-written for PyWPS-4 taking advantage of the state-of-the-art Python infrastructure in order to provide new and useful features. The current version 3 implements the WPS 1.0 standard almost entirely. The recent publication of WPS version 2.0 - which brings forth important new functionalities - is also prompting this re-structuring of the code for PyWPS-4. PyWPS offers a straightforward WPS development framework with the increasingly popular Python language. Python offers easy access to a vast array of code libraries that can be easily used in the processes, in particular those for geo-spatial data manipulation, e.g. GRASS, GDAL/OGR, Fiona, Shapely, etc., but also to statistics packages (e.g. rpy2 for R statistics) and data analysis tools (e.g. pandas). PyWPS offers storage mechanisms for process inputs and outputs and spawns processes to the background for asynchronous execution requests. Future goals of the project include automatic publication of geo-spatial results through a WFS/WCS server such as MapServer and Geoserver and support for Transactional WPS with a process scheduler. The authors present general project news like to on going OSGeo incubation and the new Project Steering Committee as well as the current state of PyWPS, and show demonstrations how these services are currently being provided.

description: Community can be a place for learning, sharing, and commiserating. You cannot deny the importance of face to face communications, so how do you find people in your area to talk about geospatial? This session will focus on the challenge of building community around geospatial technology and the lessons learned from podcasting to running events including ignites, camps, and day conferences. Boston has a large and strong technology sector within its businesses, government, and universities and yet, it is sometimes hard to see where geospatial fits into this community. This session is for people looking to start a meetup and people who are new to the community and interested in how to find community in their area.

description: This talk is about the Angular components of the early open source project Yaga. Angular serves an elegant and modern way to structure HTML-single-page-applications with its MV* pattern. Directives are one of the most powerful tools in Angular. Yaga provides directives for webmapping proposes, like the map itself, markers and different kind of layers. All directives are ready to use with two way data-binding. The main goal of Yaga is to harmonize it with Ionic. Ionic combine the power of Angular with the power of Cordova, a framework to create hybrid mobile Apps from HTML sources for all common mobile smart-devices. Additionally Ionic adds a UI that is close to the native look and feel of the mobile devices. With this stack you are able to create a GIS application for Android, iOS and Windows at once. In my talk I want to create a sample application and present the pros of Angulars two way data-binding and Ionics mobile UX design for mobile GIS applications with Yaga.

description: Drone service providers are currently spending a lot of time on researching which permissions they need to fly their drones over a certain area. Today, most governmental regulations forbid to operate drones nearby transportation infrastructures or urban environments. In our talk we present a web application build based on open source tools to visualize such geographically-bound activity restrictions and therefore ease the process for drone service providers. The resulting system makes it possible for drone service providers to draw a flight path and receive immediate feedback on which permissions they will need to fly their drones in a specific area. A user is also enabled to edit the flight path to omit certain features and view live changes on the map and the instruction list. The project is implemented using a PostGIS database to store the space usage rules (SURs) (in our case the drone regulation of a specific country). A potential flight path drawn in an OpenLayers map by the user is send to the back-end which returns the regulations enforced in that area. In the front–end WFS-requests are performed to check whether the SURs apply to the specified flight path (i.e. when one or more features triggering certain rules are close enough to the flight path). Geoserver is used to create these WFS’s, the geometries of the features are extracted from OpenStreetMap. All instructions for the flight path are visualized in an instruction list linked to the maps highlighting the features in OpenLayers and in Cesium.

description: The flexible integration of sensor data from several sources with different concepts is a interesting current research topic. This talk will show a solution which is developed as part of the “ActOnAir” project. The aim of “ActOnAir” is the development of a mobile recommendation system based on personalized environment sensor information in the e-health section. The talk focuses the sensor integration part. The system receives information from the following sources: mobile sensor devices (for particulate matter, ozone, etc.); activity trackers; human sensor information from smartphone apps. Additionally different online services for air quality data or weather information will be merged. Social Media information from concepts like “Collective Sensing” are also possible. Considering the interoperability of the sensor information the persistence of the information for data mining and visualization will be based on Sensor Web Enablement (SWE) standards. In respect to the flexibility and scalability, the presented approach will be based on microservices which provide the different sensor sources, processing steps for integration as well as sinks (such as a Sensor Observation Service (SOS)). The integration process can be defined in data streams using the provided services as modules. Also tapping into existing streams is possible. The deployment on different platforms will be easily supported, because of the microservice approach. During the talk the overall integration system concept, as well as the development of central modules, will be shown.

description: Satellite image archives provide a wealth of valuable historical data that can be used to assess changes in the environment, but extracting high quality information can be costly and time consuming if we restrict the interpretation to experienced image analysts. We attempt to reduce these limitations by crowd sourcing the interpretation process via a web based digitizing system based entirely on open source tools. This approach can lower project costs by eliminating the cost of office space and equipment for the analyst, as well as allowing flexible working hours and locations. The challenge with this approach is to ensure that the quality of the interpretation remains high. Within the context of a project to model historical iceberg occurrences off the coast of Greenland, this talk will discuss the methods we have implemented for quality control while providing training and feedback to our analysts from an interpretation expert. The business case for this approach will also be discussed, including the risks and rewards of paying interpreters for each correct feature digitized. In our case we were able to quickly and accurately interpret several hundred images resulting in the measurement of tens of thousands of features. By using cloud based image archives and client/server strategies, this approach can be economically scaled up to much larger projects.

description: Magnacarto is a new open-ource tool that makes it easier to create map styles for MapServer and Mapnik. It uses CartoCSS - a styling language similar to CSS - to create both Mapfiles for Mapserver and XML-files for Mapnik. CartoCSS provides powerful functions: You can create base-styles and extend them for specific map scales or attributes. This avoids unnecessary repetition for similar map objects. CartoCSS styles are typically just 1/5th to 1/10th of the length of comparable mapfiles. With variables, expressions and color functions (darken, lighten, mix, etc) it's possible to create new design variations by changing only a few lines of the style. Magnacarto comes with a modern web interface that shows the final map design with MapServer and Mapnik. Live-refresh and multiple map windows makes it easy to directly verify any changes made to the map style. Additionally, there is a command line tools to automate the conversion of CartoCSS to Mapfiles and XML. The presentation briefly talks about the history of CartoCSS and Magnacarto. It shows important functions, how they are used in practice and it discusses the power and limitations of CartoCSS. It will also show new and upcoming features and possible extensions (SLD).

description: In 2012, the Federal Government of Nigeria launched the Saving One Million Lives Initiative aimed at expanding routine immunization to 87% coverage that will protect over 6 million children against vaccine preventable diseases such as measles, meningitis, polio, tetanus, hepatitis, yellow fever and tuberculosis . In 2013, the GAVI Alliance approved US$ 21 million to help improve vaccine supply chains . Despite several innovations and initiatives to optimize the supply chain and storage of health commodities in Nigeria, there are still known gaps in the supply chain in the health sector in Nigeria. Achieving a good coverage of routine immunization is almost impossible without the optimization of last mile delivery – especially in the hardest-to-reach places of Nigeria. Geographic Information science (GIS) techniques play a big role in the design and optimization of last mile delivery of vaccines down to Local Government Areas and health facilities in remote places. This presentation discusses how eHealth Africa has implemented FOSS4G solutions to enhance an effective vaccine delivery system in Kano State, Nigeria; the second most populated state in Nigeria using open source tools like OpenDataKit, QGIS, JOSM, OSRM. We also discuss the importance of OpenStreetMap and open data to replicating this in other countries.

description: Exploitation of Scientific Raster Data stored in large online archives used to be cumbersome: either the data has to be transformed in an RGB version on the server using parameters supplied by the client, or the original data is downloaded and then inspected using a desktop GIS system. Browsers without specific extensions simply were not capable of dealing with the types of data found in scientific context. Today with HTML5 and WebGL browsers finally have the necessary prerequisites to create tools to dynamically visualize and explore scientific data sets. geotiff.js is a small JavaScript library to parse GeoTIFF files containing any kind of 2D raster data. The library handles various different configurations and common data types far beyond RGB data. On the other hand, plotty.js provides functionality to dynamically style 2D arrays for visualization using either predefined color scales or custom ones. In the presentation, I’m going to show how both libraries complement each other to allow a very dynamic form of data exploitation. Additionally, it will be shown how the techniques can be applied to more traditional Web Mapping concepts as dynamically styled data is displayed on a globe widget in various forms including 3D data cubes and time series of data.

Validating services and data in an SDI

uk: Комп'ютерні науки

description: To achieve interoperability in a spatial data infrastructure (SDI), conformance to specifications is essential for services and data. Service and data providers need a capability to validate their components. For several OGC standards, the OGC CITE tests provide such a capability. This covers base standards, but in SDIs typically additional specifications are added, for example, service profiles or data specifications. In the European Location Framework (ELF) the test framework ETF is used to validate INSPIRE services and data provided by National Mapping Authorities against the INSPIRE Technical Guidelines as well as against ELF-specific requirements. ETF is a test framework for spatial data infrastructure components. It supports SoapUI (for testing web services) and BaseX (for testing XML documents, including very large ones) as test engines to develop and execute test suites. ETF has been implemented in several iterations over recent years as existing open source test environments could not be configured to provide uniform test reports that were readable by and useful for non-developers. Outside of the ELF project, ETF is currently mainly used in Germany and the Netherlands, partly extending the INSPIRE-specific tests based on national profiles. We present the approach for developing user-friendly test suites and discuss typical issues that have been encountered in the ELF testing.

Needed dependencies are automatically fetched from repositories. We’ve built an early prototype of such system and tested if on GDAL build process (over 50 core dependent libraries). Now a developer with only three lines of code in CMakeLists.txt for any project he is working on can add dependent GIS library. If needed library exists in the system the build system will use it, if not - it will be downloaded from Github. Our new build system works for both Windows and Linux.

It is a robust open source geospatial platform allowing the user to organize, edit, process and publish spatial data to the Internet. MapMint includes a complete administration tool for MapServer and a simple user interfaces to create mapfiles visually. Its use does not require any coding and most of the mapfile parameters are supported, so the user can fully focus on the map features and not on its source code. The latter is generated using various WPS requests which are using the user’s data and settings as input. MapMint is based on the extensive use of OGC standards and automates WMS, WFS, WMT-S and WPS. Most of the MapMint core functions are run through WPS requests which are calling general or geospatial web services (vector and raster operations, mapfiles creation, spatial analysis, queries and much more). MapMint server-side is built on top of ZOO-Project, MapServer and GDAL and its numerous WPS services are mainly written in Python and JavaScript. MapMint client-side is based on OpenLayers, Jquery, ZOO-Client and Bootstrap and provides user-friendly interfaces to create, publish and view maps.

description: FloodWatch is a prototype application that provides location-based alerts of flooding on Pebble Smartwatches. Building on the open source flood map PetaJakarta.org, FloodWatch aims to provide residents of Jakarta, Indonesia with time critical alerts of monsoon flooding via their wearable devices. PetaJakarta.org is a real-time flood map which integrates emergency services information, social media, citizen journalism and sensor data to provide real-time situational awareness for both residents and government agencies in Jakarta. Existing disaster maps and mobile alerts require the user to interact with their smartphone device to consume and interpret reports. Alternatively, connecting real-time disaster data to wearable devices for the provision of actionable intelligence "at a glance" reduces disruption to user activity, improving time to response. Furthermore, through the use of predefined locational filters the user is able to register for alerts for specific regions of the city providing a semi-automated user-centric interface to incoming reports of disaster. This presentation examines the motivation behind developing wearable tools for disaster response in the world's fastest growing city, and explores the software's underlying open source geospatial technologies.

description: At the beginning of 2016 the Dutch SDI organisation ‘PDOK’ has released a cloud service to facilitate spatial open data publishing. PDOK is a cooperation of several public bodies: Kadaster, Rijkswaterstaat, Ministry of Infrastructure and Environment, Ministry of Economic Affairs, the four big cities Amsterdam, The Hague, Rotterdam and Utrecht, the Open Data project, the collaborating provinces unified in IPO and Geonovum. Each governmental organisation in the Netherlands can use the service to publish spatial open data sets. The goal of the project is to make data publishing as easy as possible, while being in accordance with the applicable open data standards (iso19139). The developments are based on GeoNetwork opensource and made available on Github. Metadata is automatically extracted from any uploaded dataset or taken with default values, so an user has to supply up to only 10 properties of the metadata in an easy to use form.

description: EPSG.io allows to search in a global database of spatial reference systems, datums, ellipsoids and projections to identify transformation parameters required for a software to correctly handle the geographic location in a known coordinate system. This presentation shows various functions of the search system, and demonstrates how to use it efficiently to discover and identify the right coordinate system, transform the sample coordinates online, pick a position on a map, convert units, etc. It is possible to export definitions of coordinate systems in various formats, including WKT, OGC GML, XML, Proj.4, SQL or JS and directly use these in compatible systems such as Proj4JS and OpenLayers or PostGIS. The whole system is open-source with code on GitHub, and in the background it uses OSGeo Proj4 / OGR for all the transformations and it is powered by the latest EPSG Geodetic Parameter Registry released by IOGP regularly. The open-source tools used in backend could be used called on a command line in batch operations. Ideas for future improvement and cooperation with the community will be discussed.

description: The Joint Nature Conservation Committee (JNCC) is one of a number of organisations that run inshore and offshore surveys to collect data on seabed biodiversity (e.g. species records and habitat types). The main storage and collation system for these data is Marine Recorder, a Microsoft Access-based database application developed by JNCC in 2002. Despite several updates since then, the system is now significantly out of date, and the lack of internet connectivity or the ability to store spatial data is a major problem. As a result of these issues, organisations in the UK that collect benthic data are investigating more up-to-date systems and there is a significant risk of data fragmentation. JNCC are currently in the process of moving all of our spatial data from a file based system into PostGIS. This talk will describe JNCC’s open-source geospatial information strategy and how we are integrating Marine Recorder into this, discussing the efficiency savings that this provides, as well as our plans for developing a full open-source, online replacement for Marine Recorder in the future.

description: Within the GIS community we became very fond of our web map servers and feature request possibilities to share and access data. Sharing data is relevant and applicable to other fields and communities. This led to the rise of the semantic web and to web 3.0. Clearly defined relationships between objects make it possible to interlink them and allow to search for relationships themselves. In this presentation I will demonstrate a web application that uses different techniques to access linked open data and show how the individual results can be used as input for the next search request. An open innovation platform on linked data was started in the Netherlands. One of their results was to open a server to store and access linked open data. I have used this data warehouse as a starting point for a demonstration in a geo web application. The application is based solely on open source frameworks (OpenLayers, proj4js, jQuery, and pure). The user enters a zipcode and house number, and the application uses linked data techniques to retrieve the location. This first search result connects to the next open dataset to obtain statistical information about the area. One of these statistics is the average number of bars within a 1 km radius. But where exactly are these bars? Using yet another open dataset (OpenStreetMap with Overpass API) we can pinpoint the location of bars and pubs.

description: Processing geodata can be fairly simple until the input data reaches a certain size. Creating a hillshade or extracting contour lines from a DEM can be done quickly, but if you want to do this with e.g. the global SRTM dataset (1296001 x 417601 pixel), the process will crash (unless you are visiting from the future). Besides, if there are additional steps required like clipping the data to the 400MB landpolygon behemoths from OSM or applying custom filters, you probably find yourself starting to write your own tool chunking the data. mapchete tries to solve this issue by helping you to focus on developing your geoprocess written in Python and applying this process to the data. It does so by automatically reprojecting and chunking the input datasets into tiles (based on the “WMTS simple profile”) and running your Python process for each tile individually and in parallel on all available CPU cores. mapchete offers two command line tools. mapchete_execute runs the process on the full dataset, similar to tile pyramid seeding for map caches. mapchete_serve hosts an OpenLayers interface and processes only the data in areas and zoom levels you are currently inspecting. This allows you to test and assess your process on the full dataset on the server, instead of clipping and downloading subsets on your laptop. mapchete is used as the data preprocessing backbone of EOX Maps, a service which provides background maps for example to the European Space Agency.

description: Garbage collection is a topic for sustainable cities that are moving from picking up on individual houses to pick up garbage stored on containers. Minimizing trucks on the street, minimizing the travel times, while maximizing the number of containers that are picked up are desirable of the routes planned. This kind of problems have different types of constraints, for example, capacity constraints: limited number of trucks and each of different capacity. Some are time constraints, for example, a set of driver might have the morning shift, while some others work the night shift. Some constraints are topology based: a truck can not make a U-turn or an acute turn. This presentation you will learn the concepts behind this kind of optimization problems and how FOSS4G can facilitate finding a solution.

There are almost half a million editors, most using one of three desktop editing applications: iD, JOSM or Potlatch 2. This year, a challenger appeared. MAPS.ME is an open-source multiplatform application for using OpenStreetMap offline on phones and tablets. It's extremely popular, second only to pre-installed mapping apps. With this application we are bringing the power of open maps to millions of users, and now starting to direct that flow the other way: giving millions of casual users a tool for updating the map. In this talk Ilya will share a history of adding editing features to the app, some statistics and how this change has affected OpenStreetMap, both the map and the community.

description: When you are developing applications, you need to write tests. A unit test is a test written by the programmer to verify that small piece of code is doing what it is intended to do. The tests are intended for the use of the programmer. An integration test on the other hand is done to demonstrate that different pieces of the system work together. Integration tests cover whole applications, and they require much more effort to put together. The integration tests do a more convincing job of demonstrating the system works than a set of unit tests can. Unit tests can be great but they tightly couple your tests to your code, making it really fragile and anti Agile. We will show integration testing of web mapping applications using Python bindings to Selenium browser automation tool. We can test JavaScript application from Python environment, using standard unittest module. Since Python is very easy to be used and it's very universal language, it's easy to be learned by non-programming co-workers, who can automate application tests and help the developers with testing. Using integration tests in continuous integration development, enables us to be more agile, making sure that both parts - frontend and backend remain integrated even bigger refactoring occures. Part of testing is also background data services, with new project called WMSChecker. This is used in our Jenkins environment, so that system administrators can have overview about current status of running custom nad 3rd party services.

description: Open satellite data from the US and EU have provided scientists and businesses with a wealth of data, but it can be difficult to fully easily access and process it. Recent efforts to put Sentinel-2 data on AWS S3 along with Landsat-8 has made it easier to build tools to access both data sources. At Development Seed, we are building tools called sat-utils to process and access open raster data like Landsat and Sentinel. We've expanded development on the tools to be a suite of Python libraries and command line tools for querying, downloading, managing, and processing other remote sensing data. It's been two years since we've launched the first sat-util, landsat-util, which has proven to be a valuable tool with a growing user base. sentinel-util is an tool that will provide the same easy access to data that landsat-util provides. We will discuss the processing for turning spectral band data into usable products such as color corrected RGB images, radiance data, top of the atmosphere reflectance, and various indices. We will also demonstrate the available APIs we have for open raster data: sentinel-api and landsat-api, that our client utils use for searching available metadata.

Oskari and RPC may be just what you're looking for! Oskari is an extensible and versatile map application platform which provides an easy user-interface for creating embeddable maps to websites. Embedded maps can be controlled from the website with an API to create innovative and user-friendly applications. The API includes features that allow you to 'visualize data' on the map and/or 'react to user interaction' with the map, allow users to give feedback by 'drawing on the map' or create a custom trip planner with routing features. The API can be easily extended by adding features to Oskari platform. Oskari has been originally developed by the National Land Survey of Finland, but now being developed and used by multiple organizations, also internationally. There are numerous websites already making use of embedded maps, including Finnish national e-services.

uk: Комп'ютерні науки

description: Every software platform needs three things in order to be successful: Good and solid software, reliable support and maintenance services in order to make it run smoothly, and training possibilities for the endusers to make sure they use it in a most effective way. Open geospatial software is the basis. And, with the progress that has been made in the last few years, it is among the best around. Support and other services are more and more common. In the Netherlands, you can identify several commercial organizations specializing in FOSS4G, and others adding it to their existing portfolio of services. But what about training possibilities? Few specialized training services for geospatial software are existing, and service providers might do some on-the-job training, but it is by no means comparable to the well oiled training machine that distributers of closed source software usually run. So, how to set up training courses for open source geo? At the Dutch Geo Academie we have some experience with this kind of training, and we’d like to share some ideas.

description: The Geospatial world is still facing the lack of well-established distributed processing solutions tailored to the amount and heterogeneity of geodata, especially when fast data processing is a must. However, most current distributed computing frameworks have important limitations regarding both data distribution and data partitioning methods. Hence, this paper presents a prototype for tiling, stitching and processing of big geospatial data. The system is based on the IQLib concept developed in the frame of the IQmulus EU FP7 research and development project. The data distribution framework has no limitations on programming language environment and can execute scripts (and workflows) written in different development frameworks (e.g. Python, R or C#). It is capable of processing raster, vector and point cloud data. Our intention is to provide a solution to perform a wide range of geospatial processing capabilities in a distributed environment with no restrictions on data storage concepts. Our research covers methods controlling data partitioning, distributed processing and data assimilation as well. Partitioning (also referred to as “Tiling”) is a very delicate yet crucial step having impact on the whole processing. After algorithms have processed these “chunks” or “tiles” of data, partial results are collected to carry out data assimilation or “Stitching”. The paper presents the above-mentioned prototype through a case study dealing with country-wide processing of raster imagery. Assessment is carried out by comparing the results (computing time, accuracy, etc.) to concurrent solutions. Further investigations on algorithmic and implementation details are in focus for the near future.

description: MapStore 2 is an overhaul of the existing MapStore with the goal of creating a webmapping framework which is more lightweight but still modular and easy to work with. It can leverage both OpenLayers 3 or Leaflet as the mapping engine and uses ReactJS and Redux as the core JavaScript libraries. Moreover a 3D viewer based on CesiumJS is available. MapStore 2 is both a framework and a standalone application. You can use it as a framework to develop your custom WebGis application composing MapStore ReactJS components and components from other libraries (like React Bootstrap), choosing the best mapping library for your purposes. You can also use the MapStore2 application directly, to create, save, and share in a simple and intuitive way maps and mashups created by selecting content from the server such as Google Maps, OpenStreetMap or WMS and WMTS. The MapStore 2 application consists of two main components MapManager and GeoStore, respectively front-end and back-end. MapManager allows through a unique interface to create, modify, delete and search on maps definition as well as generate a univoque link to embed a map in an external website, share your own maps with the others. GeoStore implements a flexible Java Enterprise infrastructure to manage and search maps with proper management of authentication and authorization. The presentation will give the audience an extensive overview of the MapStore 2 functionalities for the creation of mapping portals. Eventually, a range of GeoSolutions case studies of MapStore 2 will be presented.

description: The Social Tenure Domain Model (STDM) is a concept, model and information tool to map people-to-land relationships. STDM is developed and maintained by the Global Land Tool Network (GLTN) under the lead of the UN Habitat. The data model was closely aligned with LADM, an ISO standard on Land Management followed by most implementers. When it came to implementing the software tool the GLTN group decided against reinventing the wheel but to check out existing Open Source components (as maintained by the OSGeo Foundation) and Open Standards (as maintained by the OGC). So basically everything from the data model, technology standards and up to all the tools required to do proper Land Administration is already there. But it is too complex for non-technical people to grapple with. Therefore the GLTN group started to implement a software package which shipped with the right data model for the Postgres and PostGIS database, the desktop software QGIS, reporting tools and comprehensive documentation. This presentation will give an overview of the software tool and underlying components to give participants with limited technological background a better understanding of how it works and how they can also profit from the abundance of great Open Source software that is out there.

This project serves JSON map styles into web applications powered by MapBox GL JS library as well as into native mobile SDKs for iOS and Android. The same style can be rendered on server side (with the OpenGL acceleration) into good old raster tiles to ensure compatibility and portability. Maps can be opened in various viewers such as Leaflet, OpenLayers, QGIS or ArcGIS. Alternatively it is possible to use a tileserver powered by Mapnik to render the raster tiles out of vector tiles and existing CartoCSS styles made in MapBox Studio Classic. Other approaches for independent hosting and using of vector tiles are going to be presented as well.

description: Object-based image analysis (OBIA) is the current state of the art feature extraction technique for very high resolution (VHR) satellite imagery. While one proprietary tool dominated the market for years, more and more alternative solutions now appear, including free software based, and research continues to produce new approaches. However, many of the techniques implemented in free software are not easily accessible to the inexperienced user. This presentation presents efforts to develop a complete tool chain of easy-to-use modules for OBIA in GRASS GIS, ever since the development of an image segmentation module i.segment during GSoC 2012. Amongst the other modules presented are i.segment.uspo for unsupervised segmentation parameter optimization, i.segment.hierarchical for hierarchical segmentation, v.stats and i.segment.stats for the collection of statistics characterizing the objects, v.class.ml and v.class.mlR for supervised image classification. Combining these modules enables semi-automatic treatment of VHR imagery in a completely free software environment, as shown through examples of the two research projects SmartPop (funded by ISSeP) and MAUPP (funded by BELSPO). The talk will end with some reflections about possible further enhancements of this process, including through the combination of GRASS GIS with other FOSS4G tools.

description: Open data is becoming more and more available, but is mostly designed as a one-way street. Data will flow from the governments to the data users, but the information flow from users to the government is either overlooked or ill-constructed. In the case of the Dutch geographical key registries (BGT/BRT/BAG) the ambition is to get both data flows right, by embracing concepts as volunteered geographic information (VGI) and user-centred scrum development. This talk will show the 'improve the map'-application which is developed by the Dutch Cadastre, including its concepts and theories behind it, its current looks and experiences and its bright future. The application is created entirely from opensource components. Moreover, more Dutch open geodatasets are currently interested in using the application which will bring data providers and data users closer together. Our ambition is that every open dataset deserves its easy-to-use feedback application which is open to everyone. And with everyone we really mean everyone: even primary school kids will help us to keep our maps of good quality.

description: SkyGeo uses Interferometric Synthetic Aperture Radar (InSAR) by satellites for mapping ground and infrastructure deformation. This leads to maps with millions of virtual sensors, each measuring deformation by time series containing hundreds of measurements. Examples of monitoring infrastructure and managing water injection in oil fields are shown. The deformation maps and maps with derived information are delivered via a customer portal. The portal tries to provide the rather complex data derived from InSAR together with extensive features to investigate, analyze and further process the data in a user friendly way. As customers are free to use any GIS package as well as the portals own viewer, all functionality is delivered by fully leveraging the (hidden) potential of the open standards WMS, WFS and WPS. Building the portal proved challenging because of the sheer amount of data combined by the need of live rendering to allow for styling by users and dynamic filtering using WMS dimensions. On top of that, the portal must be alive 24/7, be very secure and required new functionality must be in production within 2-4 weeks. The portal should allow a growth of 10 times per year. How these requirements can be met using Docker, Nginx, Mapserver, Heron-MC, PostGIS and PyWPS and some custom components will be discussed. Special attention is given to the rich feature set while retaining standards compliance and the encapsulation of mapserver for on the fly mapfile building and easy management of a very large amount of layers.

description: Mapathons are an increasingly effective way to get data into OpenStreetMap. The Missing Maps project hosts mapathons to increase the amount of data in areas that don't have large local OSM communities. The American Red Cross and Development Seed have built an analytics platform that tracks user trends in real-time and rewards contributors for their efforts, as can be seen at missingmaps.org OSM-stats tracks user's activity, consistency and relative reputation, reporting detailed metrics and awarding a variety of themed badges based on the type and magnitude of contributions. Badges range from simple tasks ("Add 4 roads") to challenging ("Map in 10 countries"). Leaderboard pages display up to date detail on the most active users for a current project, while hashtag groupings display statistics to be separated out, allowing tracking of groups. A map of each users commits can be seen, as can a map view indicating the last 100 changes. Most of the contributions for the Missing Maps project occur during mapathons where hundreds of volunteers submit edits and additions over a couple of hours. This means that the system needs to handle large spikes of activity when thousands of edits are added. We deployed the OSM-stats components using AWS Lambda functions and Kinesis streams. These scale very well to meet the needs of Mapathons and incur minimal cost when not in use.

Users can search through a web-based map browser, conduct geographic queries to an API, upload imagery to publish openly licensed imagery, and process imagery into tile map services. Searching through many sources of imagery in a usable way was one of the biggest challenges we saw when designing the system. We knew usability was going to be critical to the adoption and success of OAM so we created a new type of grid interaction to search and find imagery. This talk will present the design and technical build process for developing the new OAM map browser and the open source tools that power the system. We'll discuss our UX experiments and how they influenced the build process, and talk about how and why we used React JS to build a grid-based imagery browser.

description: Flooding remains the most widely distributed natural hazard in Europe, causing significant economic and social impact. Nowadays, availability of earth observation data generates fundamental contributions towards mitigation of detrimental effects of extreme floods. The technological advance allows development of online services able to process high volumes of satellite data without the need of dedicated desktop software licenses. The talk presents the data, the algorithms and the technologies used to develop such an online system that can use multi-scale satellite data, together with reference and in-situ information, to map the areas affected by floods and giving the users the possibility to inspect, process, analyze and validate the information. The platform, created by National Meteorological Administration of Romania, offers services based on Open Geospatial Consortium standards for data retrieval (WMS, WCS, WFS) and server-side processing (WPS, WCPS). The services were built using open source solutions such as GeoServer, OpenLayers, PostGIS, GDAL, rasdaman.

description: Security is a major concern in the enterprise and treats all aspects of identity and access management. Moreover the proliferation of devices and digital assets connected to the Internet of Things is a massive source of growing geographic information. GeoServer has buit-in a lot of features to manage authentication and authorization but often this kind of problem can be better dealt with a dedicated tool (i.e. Forgerock IAM suite) which allows to provide identities and access policies likewise to several clients. What are the best practices to integrate GeoServer into an existent single sign-on and identity lifecycle? Althought tools like CAS and GeoFence allow to enable such features it's more likely that GeoServer needs a leaner and cleaner path towards the externalization of authentication and authorization for the OGC services and its REST API.

With an understanding of geographic web maps as documents of composite structure i want to share and discuss a LeafletJS implementation representing this investigation. Building on the descriptive markup and this model of a geographic web map i also want to share the idea of developing a user dialog which could support readers of maps in analyzing WHO contributed WHERE, WHEN - and WHAT is the map about. The Leaflet.annotate API can be seen as an interface proposal for other authoring tools or geographic content management systems and with that I hope to contribute to a discussion around accessible and responsible publishing of geographic maps on the WWW.

description: Land administration is an ongoing concern in many countries of the world and less than 30% of the landcover is properly titled or surveyed. This lack leads to insecurity of tenure, economic barriers, land grabbing and is a major problem to resolving land conflicts. Land administration frameworks have to support a wide variety of regulatory and policy environments and interoperability is key in providing the necessary flexibility. In order to avoid the creation of yet another set of data silos OGC members set out to form a Domain Working Group (DWG) on Land Administration as a forum to explore existing interoperability standards and best practices in this domain. The presentation will focus on this newly established working group and introduce to some of the key points of interest. While there are some standards describing elements of an administrative system (for example ISO LADM), there is no consistent use of geospatial description of land records or adequate rules for defining and describing the quality of the records. The group will work to provide a common vocabulary for the locational aspects of land administration databases and will also be a forum for connecting suitable technology for data linkage and quality assessment. Some of the key players in the Land Administration domain have created Open Source tools like FLOSS SOLA (FAO) and STDM (GLTN and UN Habitat) which are based on core OSGeo technology and already make extensive use OGC standards.

description: deegree surely is one of the most mature OSGeo projects. Its OGC web services are comprehensive and some of them even are reference implementations. When it comes to building spatial data infrastructures like INSPIRE you need a little bit more than spatial data and services. You need a whole infrastructure capable to meet high performance goals and 24x7 availability, which has to comply to strict Service Level Agreements. In short: you need a comprehensive software stack containing tools for service and data management along with metadata and user management tools for publishing spatial data in a trusted and secure environment are needed along with appropriate monitoring tools to assure the infrastructures availability. The deegree community project did not provide this functionality yet and that was why two German companies grit and lat/lon joined forces to build the “deegree Enterprise Edition”. deegree Enterprise Edition contains all the tools mentioned above. Further on it includes appropriate contracts offering software maintenance and professional support. These contracts offer the same support and performance as maintenance contracts for proprietary software do and fully meet the requirements of the maintenance contracts used in the German Public Sector. Nevertheless deegree Enterprise Edition is still open source. But it is open source with guaranteed SLAs. Such it offers an opportunity to all organisations under INSPIRE obligations to professionally operate INSPIRE. The presentation shows: the motivation to build deegree Enterprise how the deegree Enterprise Edition differs from the community edition how the business model is working

description: This presentation focuses on the role of reference implementations for the OGC standards process and gives an insight in the related OGC Compliance Program. OGC Standards are developed in the OGC Standards Program and follow rules and guidlines that have been set by the OGC's members. Before an OGC standard is adopted by the OGC membership, a public review period is required where non-members can also contribute. Increasingly, some standards working groups also decide to work more openly in the public (like the GeoPackage work group did) to be more inclusive. OGC interface standards also come with reference implementations. The OGC rules state that these have to be "free and publicly available for testing". Some well known OSGeo projects like GeoServer, MapServer, deegree and others are reference implementations of OGC standards. A Reference Implementation is a -> fully functional, licensed copy of a tested, branded software that has passed the test for an associated conformance class in a version of an Implementation Standard and that -> is free and publicly available for testing via a web service or download.

description: Over 70 percent of land in Sub-Sahara Africa is not documented or included in the formal land administration systems, current requirements of land information systems has created a hindrance rather than facilitate security of land tenure. Cadasta Foundation is aiming to build “fit-for-purpose” land tools that focus on making it possible for communities, governments and non-governmental institutions to document land tenure rights, without the rigid requirement imposed by current land information systems, land tenure documenting procedures and physical boundary accuracy. “Fit-for-purpose” terminology was coined at a world bank conference, where stakeholders realized the need to come up with different approach when developing land administration systems. Cadasta platform is an open source project built on top of django. This fits well, on the requirements of a land information system that is flexibility, affordable and attainable for recording land rights. Cadasta platform extensive API and functionality allows it to be connected to GeoODK, which is essentially ODK with added functionality for mapping and spatial features. This makes GeoODK an ideal tool for participatory data collection, something that has been advocated for in “fit-for-purpose” approach to recording land rights information.

Using PostGIS in a real advanced way!

uk: Комп'ютерні науки

description: A lot of people use PostGIS as a basic GIS toolbox, but very few use it in a real advanced way. To progress towards full PostGIS power, we can first make use of advanced native PostGIS functions. Using some extensions related to PostGIS, such as SFCGAL (for 3D data management), PostGIS Raster, PgPointCloud or even the latest pgsql-postal (for address normalization)... Then we can mix PostGIS functions with advanced standardized SQL features provided by PostgreSQL 9.x itself (CTE, Window functions, FDW, join and aggregate pushdowns…). Even better, use PostgreSQL bindings for data analysis languages such as R or Python to create your own dedicated function set, and integrate them into your SQL queries. We conclude this session with perspectives on what the combination between GIS and data science could be.

Dealing with change - OSRM Version 5

uk: Комп'ютерні науки

description: The Open Source Routing Machine (OSRM) is a routing engine, providing blazing fast route-finding on global data sets like OpenStreetMap. With Version 5 of OSRM we tackled two challenges: providing a world-class navigation experience for car drivers and making OSRM easier to work with for developers. To deliver great navigation, we made route duration estimates more realistic, by allowing developers to provide custom speed and turn duration data. We also dramatically shortened pre-processing times and improved turn-by-turn guidance. To deliver a great experience to developers we modernized the code base and improved the build and test systems. We also refactored the HTTP API to support the new features and removed historical short-comings. In this talk we will introduce the subject of routing in general and then explain the new features of OSRM Version 5 in detail. We will highlight the trade-offs we faced and the reasoning behind our decisions.

We'll transform the standard desktop application to a version tailored for tablet use including a finger-friendly interface, camera integration and full offline editing support with data synchronisation. Taking QGis where no QGis has gone before, we take the theory into Flanders fields. We demonstrate the possibilities of the technology with a use case where QGis is used in the field to assess soil erosion in the hills of Flanders. Thanks to a strong foundation and simple yet powerful customization options, we learn that Qgis can really outperform your expectations, even outside of its (or your?) comfort zone.

description: Focusing on a clearer and more visible passenger information, Swiss Federal Railways SBB modernized the general displays in the biggest Swiss railway stations. The former mechanical palette displays were replaced by LED screens of up to 5 meters width. In case of severe traffic disruptions these monitors are used for providing the passenger with general information. Additionally, a huge (perhaps the biggest) map based on OpenLayers 3 is shown on the monitor enabling the passenger to get a fast overview of the situation. The key component of the service-based architecture is the geographical content management system Cartaro. It is used by the employees in the SBB operation centers for composing and editing the information to display. Among issues like performance, reliability and availability a major challenge for the system was the development of tools for the fast and simple creation of a clear and appealing map. The software automatically generates a map based on real-time timetable information, identifies the affected stations and highlights the interrupted route using a routing-based approach. A set of integrated spatial editing tools enables the user to e.g. modify route geometries at different generalization levels and to align map labels.

Main focus lies on practical applicability by consultant engineers and the flexibility to connect to different simulation packages. By using one system for data preparation for different simulation packages, a higher efficiency leads to reduced time and costs. The data is stored in a database, either SpatiaLite or POSTGIS. The tools are developed using the database functions because of the high efficiency.

description: Large point clouds have emerged across a wide range of disciplines, however users and managers face a bewildering range of storage formats, large datasets and convoluted workflows for analysing point clouds alongside other data. Services like OpenTopography and the PDAL toolkit enable point cloud discovery and use, but integration with other earth systems data is not transparently supported. The Australian National Computational Infrastructure (NCI) hosts 10+PB of research data, predominantly in the realm of Earth Systems. These include extensive point cloud data which need to be discoverable alongside, and interoperable with, substantial collections of geospatial observations and model data using common tools in a High Performance Computing (HPC) and High Performance Data (HPD) environment. NCI has created a National Environmental Research Data Interoperability Platform (NERDIP) to help manage and analyse the data, both locally and remotely using web services which makes use of advanced features in HDF/NetCDF. We have demonstrated that deploying other geospatial data using a HDF5 model has the potential to directly improve large-scale usage and increase data interoperability between diverse geospatial collections. Models such as the Sensor Independent Point Cloud (SIPC) and SPDLib are based on HDF5. NCI are currently evaluating the use of these formats to aid discovery, extraction and processing using readily available tools, as well as interrogation via web services. The end goal for NCI is making point data discoverable and accessible to end-users in ways which allow seamless interoperability with other datasets and processing techniques.

description: Until 2015 the Norwegian cadastre data was a closed data source, practically unavailable for commercialization. Authorative thematic data sets are widely produced by federal governments which, by law, are open and freely available. Norkart Webatlas strategically formed business cases and aimed at commercializing and generating a foundation for jobs based on open spatial data. Two years into this race we will share our experiences: pitfalls and successes which have paved the roads for a sound business providing solid jobs for tens of people. Changing the way clients think about "open", pushing clients to develop under open licenses and internally adopt a "open" mindset are some of the challenges we faced. In this talk we will share how we have done this and hopefully inspire others to generate solid jobs based on open data and open source software.

description: In januari, the European Space Agency launched the first version of the PROBA-V mission exploitation platform. proba-v-mep.esa.int. This platform, which is fully operated by VITO Remote Sensing, has the goal to simplify the use of open remote sensing data which should eventually result in operational applications that benefit society. Exploitation platforms are the way of the future to handle the ever increasing volumes of remote sensing data, and at VITO we believe that the use of Open Source software is the only way to collaborate on this shared vision. In this talk, first I want to give a general overview on what users can do with the PROBA-V MEP. This involves using an Openstack VM loaded with FOSS software and direct access to the dataset, to access an Hadoop cluster where a user can distribute his processing using Spark. Secondly, I want to show how we are using Geotrellis to support interactive queries on the full timeseries of remote sensing data that is available in the platform. Also showing how this can be done from within an interactive Scala notebook in the browser.
