description: Changing data distribution from one relational database system to another should be an easy task. SQL is a standardized database language and concepts concerning spatial data is much the same through OGC standards. Still, some tasks has to be done in a slightly different manner. The Danish Geodata Agency decided to explore changing a major part of its data distribution from a commercial Oracle Spatial database to an open source PostGres/PostGIS database. A pilot project was set up to evaluate PostGIS as a productive distribution database accessed by a lot of users through open source services. Experiences were positive and the pilot system was upsized to a full scale production system. The database setup is designed to facilitate sufficient performance and ensure constantly running service. Databases and services are replicated and a master-slave relation is established between the databases to ensure immediate copying when new data are transferred from the authoritative database. A special challenge was the change-over from the old system to the new one while services were still running. New data are copied on a daily basis. Old and new system were run in parallel for a short while to be sure that the new system was stable. The change-over has mainly been done by inhouse employees, which were non-specialists in open source products. Documentation and expert service companies are available if help is needed. Experiences are positive.

description: The geological borehole, depth profile and layer-data and some background-data such as topographical maps were setup as services, mainly in a PostGreSQL/PostGIS and GeoServer environment. Both webclients are fully client-side based applications, for the 3D-client WebGL for rendering is used and all data is delivered via standarized services. For the 3D-data the X3D format is used, which is not an official OGC standard yet but delivers phantastic possibilities for 3D-modelling of data in a webbased environment. The talk will focus on some of the high-end announced requirements, especially to the 3D-webclient such as gazetteers, FeatureInfo or dynamic load of services such as WMS or WFS. A special task is the delivering of borehole data as BoreholeML, for which the GeoServer app-schema extension was used. From a technical point of view especially the development of a GeoExt-like library which connects X3dom and ExtJs 4.x is an interesting part. With this solution, elements such as gazetteers and presentation-masks for requested attribute data could be used in both 2D- and 3D-client. At the end some live impressions of the application will be shown.

description: ODVIS-AT is a project funded by the Internet Foundation Austria and Salzburg University of Applied Science. The goal is to display open data (demographic, open government data) in a quick and easy way to end users. In 2011 the Austrian cities Linz and Vienna launched two Open Government Data services where information was published in textform (csv, pdf, json, etc.), other public authorities joined soon (find a current list at data.gov.at). In an attempt to make this data visible we started the development of a visualization service in 2013 where published data is linked to geodata and the result is put on a map. The project consists of an internet portal (odvis.at) and an api to query the data and allow personalization and combination of information. At the moment the project is still in development phase but scheduled to be finished in September 2013. The project adresses a public audience as well as researchers, journalists, students and developers. Data can be accessed from a central service that provides a snapshot of currently available government data. On thehe backend the visualisation is rendered as a graphic layer to be used with Open Street Map, using Mapnik and a postGIS module. Rendering on demand allows filtering, combination of data sets, mathematical computation (via the api) and hence the personalisation of the information display. In the presentation at FOSS4G we would like to show the project status (finished version should be ready) and experiences with the project.

Old Maps Online And Georeferencer

uk: Комп'ютерні науки

description: Hundreds of thousands of historical maps have now been scanned and made available on-line by libraries around the world, and this has been a great boon to anyone interested in the history of cartography. Despite this fact it is hard to find scanned maps covering area of interest in the large number of online catalogs, library systems and web presentations on the web. The traditional fulltext search engines, such as Google, is failing to index the scanned maps properly. Old Maps Online is a search system tailored just for historical maps. Pick a location on a world map, or type in a place-name, narrow the search by selecting a date range. A listing of all possible maps covering that location appears, ordered by best geographical match. Select a map, click on the link and you go directly to view the map on the original librarys website. You dont need to know who holds the map, just where in the world you want to look at. This system is designed to complement rather than compete with libraries' own search interfaces. The system is powered by the enhanced version of the MapRank Search technology and indexes over 130.000 scanned high-resolution maps already. Many major collections in the US, UK and elsewhere have agreed to contribute: The British Library, Harvard Library, National Library of Scotland, David Rumsey Map Collection, Dutch National Archives, Moravian Library, New York Public Library, Norman B. Leventhal Map Center at the Boston Public Library, National Library of Australia, etc. Our aim is to include as many collections as possible, so map libraries and collectors are encouraged to participate. To be able to index the scanned maps geographically, we must be supplied with minimal metadata (title, creator/publisher, date, identifier, and a stable url), plus geographic coordinates for the area covered, for each map. We can suggest/provide tools you can use to create the coordinates. One of the tools is the Georeferencer online service, which allows rapid collaborative georeferencing, 3D visualization, annotation and accuracy analysis of scanned online maps directly in a web browser environment, without the need to install any software on a local computer. The online visitors can help with the metadata enrichment and georeferencing of the scanned maps - and they are motivated with competitions, rewarding, community participation and recognition during this crowdsourcing effort. The Georeferencer service is applied in several institutions such as the British Library (London), the Moravian Library (Brno), the Nationaal Archief (The Hague), the National Library of Scotland (Edinburgh), and the Institut Cartografic de Catalunya (Barcelona).

description: Web mapping has become very exciting in the last year or two. Many new products have come onto the market that make the creation and publication of web maps easier by an order of magnitude. The demand for quick and easy web maps isnt a new one, so why is it only now that were seeing products that address this need enter the market? The answer is twofold: first, cloud computing has has hugely reduced the cost of running resource hungry map servers; and, second, the open source building blocks that most of the products featured in this presentation utilise have reached the level of maturity required to build reliable, scalable products on top of them. Most of this new generation of cloud based web map publication products are indeed standing on the shoulders of giants and wouldnt exist if it wasnt for the tremendous work done by the open source GIS community over the last decade. This presentation will be a follow up to my free ebook released in March entitled Online GIS - Meet the Cloud Publication Platforms that Will Revolutionize our Industry (www.onlinegis.com), the presentation will take a closer look at the products covered in the book and particular the open source building blocks that make them possible. You no doubt are wondering is why the CEO of a web map software company would want to give a presentation that not only looks at his product but also those of his rivals. The short answer is that I get asked all the time what the difference is between these products and also see the same question asked many times in online forums and social media channels, so its obviously something that needs answering. I also dont view most of these products as our rivals, although all of the products featured in this presentation are capable of similar end results; the steps required to achieve those results differ hugely, with each aiming to make that process as smooth as possible for a certain type of user, be it programmer, casual GIS user or GIS analyst. After this presentation youll have a good idea of the differences between ArcGIS Online, CartoDB, GeoCommons, GISCloud, MangoMap and Mapbox, you will also have a clearer idea of which of the products is best suited to your unique needs and requirements as well as the open source building blocks that power them. This presentation isnt going to show you how to use these products, but it will show you what is possible with each of them and what it takes in order to achieve the best results.

description: The cloud can be used as an infrastructure, as a platform or as a (desktop) software replacement according to the three different paradigms that it supports (IaaS, PaaS and SaaS). On the other hand at the moment more and more applications are using the cloud as their backend since it promises (unlimited) scalability and elasticity in terms of storage and computing power. In the open source geospatial world a lot of effort has been invested in developing excellent software that can be used to store, manage, visualize and publish on the web geospatial data and services. But when it comes to the cloud those offerings are not always readily available since the software, we all build, does not scale in a way that can take advantage of the cloud. In that respect we worked towards providing scalability and elasticity capabilities for the storage, querying and visualization of geospatial data based on existing open source solutions like the Mapserver, PostGIS, Apache and so on. We also worked on the lower part of the software stack so that we can build an elastic file system for storing geospatial data. So we are in the process of offering a fully open source solution that can take advantage of the cloud and its properties. Moreover we have coupled this solution with support for publishing anyones geospatial data as Linked Open Data so that they can be readily combined with other data on the web. In that respect we are using an open source SPARQL endpoint (Virtuoso) that allows us to store geospatially enabled information given that a suitable conceptual model will be provided described in RDF. Thus we allow for seamless integration of published data on the semantic web and we provide the necessary services for integrating this kind of offering in other applications in the future. Additionally we identified an emerging need to allow end users to publish their own data and create dynamically their own customized services on the cloud. Thus we exploit clouds unlimited storage capabilities to allow end users to publish their own data (as long as it is cost effective, too), combine them with existing data and create their own WMS/WFS customized services and publish them on the web. This has a great value-added for the users since they can actually publish their own maps. Finally, we demonstrate the capabilities of our technical solution by building and offering a set of advanced geophysical services through the platform. These services include a service for creating shakemaps (maps the visualize the effects caused by an earthquake to the environment), predicting landslides (providing maps assessing the possibility of landslides) and handling pollution information in ground waters. In conclusion, we offer an open source software stack that is based on existing open source software and extends it as needed in order to take to the most possible advantage of the properties of the cloud. We have tried to keep the software agnostic for the specific cloud and its capabilities. The work is carried out within the INGEOCLOUDS FP7 Project, co-funded by the EU, and with the participation of companies (AKKA technologies, France), research centers (CNR, Italy and FORTH, Greece) and data providers like geological surveys (GEUS, Denmark; GEO-ZS, Slovenia; BRGM, France and EKBAA, Greece) and earthquake research institutes (EPPO, Greece).

description: Open source software is well established for basic raster and vector data processing, with the Geospatial Data Abstraction Library (GDAL) as one of the most well known tools. Its utilities and application programming interface (API) have become a common standard for data format conversion, reprojection, spatial and spectral subsetting. With its command line interface utilities, GDAL is better suited for the automatic processing of very large amounts of data and for repetitive processing tasks than most of its commercial counterparts. Though GDAL provides an excellent API on which more advanced image processing tasks can be built, not all users have the time or programming skills to get involved such development. In particular within the remote sensing user community, there is a large interest in machine learning techniques applied to remote sensing data.

description: The impressive list of OSGeo Projects [1] show the necessity to develop OpenSource software. Behind all lines of code, there is the work of one developer. And, in our capitalist world, work means money. This presentation will underline the challenges of the crowdfunding effort organized for the development of the next major release of OpenLayers 3. OpenLayers is one of the most famous OSGeo library and is widely used for the development of web mapping applications. Its development started in 2007. In 2012, it was clear for the developers that the current release was at the end of its life. The emergence of new technologies implied to create a complete new libraries based on these new technologies. As usual in the OpenSource world, some developers started this work in the middle of 2012. Since a complete rewrite was required, it appeared clearly that the work needed to obtain a library that would allow the migration to the new release was huge. It was estimated to 2500 hours of work. At this time, swisstopo planned a migration of its web mapping applications. swisstopo decided to use the future release of OpenLayers, which was only a very first prototype. In order to benefit of the advantages of OpenSource developments made by a community, it was not possible for swisstopo to simply mandate a company for the development of this library. The commitment of the OpenLayers community and its committers/developers was needed. So, in order to speed up the development process, swisstopo decided to invest a substantial amount of money and to organize a crowdfunding effort together with companies active in the OpenLayers development scene. Several financement channels were used: micro fundings from individuals and more important fundings from companies and administrations. This presentation will describe the main problems and challenges faced during this crowdfunding effort and how they have been solved. Here is a list of these problems and challenges: - Some key actors had to be convinced to donate in order to convince others to follow the movement. It is important that one or two big players make the first donations. And, since the money is managed by the higher manager, a lot of energy has been put in explaining how an OpenSource community works. The OpenSource development model is still not very well known and the higher management often think that a normal contract with one company is the best way to develop softwares. - The general objective was to be clear and strong enough in order to convince individuals, companies or administrations to invest on something that didnt exist. - The financial capacities of individuals, companies or administrations are not the same. But all are part of the OpenLayers community. It was important to be able to handle donations of some dollars to some thousand of dollars. - OpenLayers is an OpenSource community, but is not a legal entity. Its therefore not possible to make a contract with OpenLayers. In order to solve that, the main companies of the OpenLayers development scene decided to create an association in order to simplify the administrative aspects. - The commitments and the resources of the OpenLayers committers was needed in order to ensure that the library could be developed in a short time frame and with the necessary level of quality. - A worldwide communication concept has to be put in place in order to reach all potential crowdfunders. And this only with a few persons working partially on this project. - An organization had to be put in place in order to coordinate the work of persons located all around the world. But at the end, the result is here: more than 350000 USD have been found and the development of OpenLayers 3 is a reality. And everyone can now benefit of a modern, performant and 2D/3D web mapping library, thanks to all crowdfunders and developers !!!

description: OpenLayers 3 is the next generation of web mapping. A radical new architecture and the use of cutting edge JavaScript techniques, libraries, and tools enables a full suite of previously unimaginable functionality while maintaining a compact, high performance library. In this talk we'll show you how to use this functionality in your applications, and peek under the hood to see how OpenLayers 3's architecture makes it possible. We'll include: Virtual globe (Cesium) integration: a carefully designed camera and data source abstractions permit close integration with the virtual globes. Switch between 2D and 3D views of the same data, or display synchronized 2D and 3D views side by side. Multiple rendering back-ends: a pluggable rendering architecture supports multiple renderers for maximum performance and portability. A Canvas 2D renderer provides fast, reliable rendering on current devices, a DOM renderer provides fall-back capabilities for older browsers, and a WebGL renderer opens the door to the next generation of performance for the most demanding applications. Rich data sources: generic and powerful core data representations of tiled, single image, and vector data make it easy to add support for a wide range of geospatial data sources. Smooth and flexible interaction and animation: an optimized rendering path ensures that interaction remains smooth at all times. Compact library size: use of the Closure suite of tools creates keeps the build size small while keeping the source code readable.

OpenWIS Opensource Software

uk: Комп'ютерні науки

description: OpenWIS OpenSource Software The World Meteorological Organization (WMO) has been working for several years towards upgrading its global infrastructure to support all of its international programmes of work, both operational and research-based, to collect, share and disseminate information. The new infrastructure is called the WIS ( WMO Information System). It identifies three top level functions, namely: GISC: Global Information System Centre; DCPC: Data Collection and Production Centre; NC: National Centre. Météo-France, the UK Met Office, the Australian Bureau of Meteorology, the Korean Meteorological Administration and Meteo France International have developed the OpenWIS software, coupled with their existing systems, to perform the three functions required by the WMO Information System; that is, GISC, DCPC and NC. Based on opensource bricks, with GeoNetwork, OpenAM, JBoss, Apache, Solr and PostGreSQL, OpenWIS is going to become opensource. Beyond the WIS requirements, the OpenWIS consortium is building new functionalities for OpenWIS that will fit the OGC (OpenGeospatial Consortium) and INSPIRE (European directive) aspects, with standards OGC interfaces, a portal providing the viewer function with the discovery, search and request possibilities, and in a short future the billing and the transformation services. The current functional components of OpenWIS are: Data Service and its cache of essential data Metadata Service (ISO19115 catalogue synchronised with OAI-PMH protocol) Security Service Monitoring and Control Portal (Discovery, Search, Browse, Request, Subscription) Météo France operates various dissemination tools. OpenWIS provide a generic interface that Météo France has adapted, covering requests for dissemination and their monitoring. OpenWIS interacts with data sources to respond to ad hoc or periodic subscription requests either directly via harness connections or relying on SOA OGC infrastructure. The new challenge of the consortium is to share the opensource model and expand membership beyond the founding members. The reflexion within the consortium enables to give some trends: A steering committee for the integration of new functionalities (spontaneous or not) One or two licences (the portal and the metadata component inheriting of the GeoNetwork licence) A strong but reduced team for the initial developpement (MetOffice and Meteo France) Git for the management of versioning and integration The will to put the soft on the shelves of the World Meteorological Organisation Entrance in the opensource area by the end of 2013

description: This presentation will provide the attendee with an introduction to data processing in GeoServer by means of WPS, rendering transformations and SQL views. We will start by a brief introduction to GeoServer 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. The presentation will move on showing how to integrate on the fly processing in WMS requests, achieving high performance data displays of heatmaps, point interpolation and contour line extraction 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 GeoSever perform the processing, the analytics abilities of spatial databases are not to be forgotten, the presentation will move on showing how certain classes of processing can be achieved directly in the database. Eventually, the presentation will close with some guidance on how to choose the best processing approach depending on the application needs, data volumes and frequency of update, mentioning also the possibly to leverage GeoServer own processes from batch tools such as GeoBatch. At the end the attendee will be able to easily issue WPS requests both for Vectors and Rasters to GeoServer trhough the WPS Demo Builder, enrich SLDs with awesome on-the-fly rendering transformations and play with virtal SQL views in order to create dynamic layers.

description: pyModis library is a Python library to work with MODIS sensor satellite data. It was originally developed as an interface to download MODIS data from the NASA FTP server but it has grown into a powerful library which also offers further operations on the data. pyModis has several features: - it supports downloading of large numbers of original MODIS HDF/XML files. This is ideal for the automated continuous updating of a local archive through a cron job; - it can parse the XML file to obtain metadata information about the related HDF files; - it can convert a HDF MODIS file to GEOTIFF format; - it can create a mosaic of several MODIS tiles to obtain large coverages including the creation of the merged XML metadata file with information of all tiles used in this mosaic. For format conversion and mosaicing the MODIS Reprojection Tool (MRT) is required, because at time MRT is the best free and open source software to manage original MODIS data and convert them into a different projection system or format while taking care of the special features of the original Sinusoidal projection. pyModis is composed of three modules: - downmodis.py contains a class downModis used to download MODIS data, it requires a password for the FTP transfer (usually your email address) and a path where to store the downloaded data. Other parameters are optional, such as the date range or the MODIS product to be downloaded; - parsemodis.py contains two classes, parseModis that parses metadata of a HDF file returning all useful information. It has also the capability to create a configuration file for MRT; the other class is parseModisMulti, it reads metadata of several HDF files, hence it is used to create the XML file for a mosaic. This class is also able to return the bounding box of all the tiles; - convertmodis.py is the module to do some simple operations on the original HDF files such as reprojection. It contains three classes and all of them require the MRT software to be installed. convertModis converts HDF files to GeoTIFF format; createMosaic creates a mosaic from several MODIS HDF files into a single HDF file; and processMosaic converts the raw data of MODIS using swath2grid from MRT-Swath. In pyModis the user can also find five command line tools to easily work with pyModis library: - modis_download.py is the tool to download data, - modis_parse.py reads metadata of a HDF file, prints information or writes them to a file, - modis_multiparse.py reads metadata of several HDF files and prints bounding box or writes the MODIS XML metadata for a mosaic, - modis_mosaic.py creates a HDF mosaic from several HDF files, - modis_convert.py converts MODIS data to GeoTIFF or other formats and as well as different projection reference systems. During the presentation all these topics will be discussed and illustrated along with more information about the future of pyModis and the tools for the community (how to contribute or how to report a bug or an enhancement).

description: The purpose of this presentation is, on a side, to dissect the developments performed during last year as far as raster data support in GeoTools and GeoServer is concerned, while on the other side to introduce and discuss the future development directions. Advancements and improvements for the management of raster mosaic and pyramids will be introduced and analyzed, as well as the latest developments for the exploitation of GDAL raster sources. Extensive details will be provided on the latest updates for the management of multidimensional raster data used in the Remote Sensing and MetOc fields. The presentation will also introduce and provide updates on the JAITools and ImageIO-Ext projects. JAITools provides a number of new raster data analysis operators, including powerful and fast raster algebra support. ImageIO-Ext bridges the gap across the Java world and native raster data access libraries providing high performance access to GDAL, Kakadu and other libraries. The presentation will wrap up providing an overview of unresolved issues and challenges that still need to be addressed, suggesting tips and workarounds allowing to leverage the full potential of the systems.

This presentation will introduce this new way to not only edit, but mostly to manage, mapfiles. No matter how much data you have, how many mapfiles or the complexity of your symbology, it will help you sort out the essential by removing the iterative part of the process. Getting rid of all of this error prone copy-paste as well! Scribe is a python script that allows you to write a configuration file instead of a mapfile. The configuration is similar to Basemaps, but simpler to use and less verbose.

SVG Map - Tile Map Without Javascript

uk: Комп'ютерні науки

description: In this presentation we will show how the SVG Map technology can display a tiled map without Javascript. Many popular internet tile maps such as OpenStreetMap, Google Maps, etc. use Javascript to provide tiling and layering. But this can cause high load especially on mobile platforms. SVG Map instead implements specific elements and attributes, that enable internet browsers to display map tiles directly through the browser's layout engine, with support for dynamic tiling and layering. The core mechanism of this tile map is the SVG iframe element. Depending on zoom level, map layer and viewport the relevant map data is downloaded using media queries. The globalCoordinateSystem element allows to define the geographic coordinate system and to describe transformation rules. SVG Map will make it possible to display maps in the browser with SVG files alone, and it will allow to style maps with CSS. While a first prototype has been is developed using Javascript, development has started on implementations for Webkit browser and a Firefox add-on. Because Firefox OS doesn't support add-ons, the native implementation in Firefox browser is also planned. The final aim is to make SVG Map a W3C standard, and discussion has already started in the SVG Working Group at W3C.

description: Data conversion combined with model and coordinate transformation from a source to a target datastore (files, databases) is a recurring task in almost every geospatial project. This proces is often refered to as ETL (Extract Transform Load). Source and/or target geo-data formats are increasingly encoded as GML (Geography Markup Language), either as flat records, so called Simple Features, but more and more using domain-specific, object oriented OGC/ISO GML Application Schema's. GML Application Schema's are for example heavily used within the INSPIRE Data Harmonization effort in Europe. Many National Mapping and Cadastral Agencies (NMCAs) use GML-encoded datasets as their bulk format for download and exchange and via Web Feature Services (WFSs).

Gaia3D Inc., has involved in one part of mobile service which displays traffic status on roads, streets, and highways up on geographical map, making people easily check the status of traffc wherever theyre heading. Gaia3D Inc., will introduce not only the experience of implementing mobile traffic map service (iPhone App, Android App, and Mobile Web Client) showing traffic on roads, streets, and highways at NTIC using Squid Proxy Server, GeoServer, and SQL Server but also advanced architecture coming up in 2014. NTIC system collects all kinds of real time traffic data of all highways, routes, streets, and roads in South Korea and divides those collected traffic data into three colors in green, yellow, and red by speed. These colorized traffic data are mashed up with map data to service on mobile devices. Servers carry out tiling traffic map in every 5 minutes and clients receive and display those tiled data. This system aimed at tolerating peak times of two major holiday seasons in South Korea - Chuseok(Korean Thanksgiving day) and Seolnal(Lunatic New Years day) when almost 15 million people per day travel at the peakest dat and about 8 million vehicels are poured out to roads, streets, and highways, so the system should be designed to safely handle over 100,000 concurrent connections. The whole system is consisted of two Cache Servers with Squid Proxy, six Map Server with GeoServer, and three Database Server with SQL Server. Real time traffic information and road lines are managed in SQL Server and provided to GeoServer. Traffic map tiles are produced in GeoServer and are passed to Cache Server. The client is designed to request tiles via interface of WMTS(Web Map Tile Service) protocol with Time Tag. The very initail architecture designed in 2012 somehow managed to endure traffic loads at peak times, but had some problems, which was quite disappointing and unexpected results. In order to improve the system, weve mainly focused on the enhancement of scalability. Also, weve newly redesigned the system into seperating tile producing servers and managing static contents using NGINX web server.

description: Digital distribution of geodata makes it possible to improve the efficiency and accuracy of our professional users' data collections on an ongoing basis. The Agency's Digital Map Supply is a national infrastructure to distribute geospatial data to all kind of users. Subscribers to the Digital Map Supply receive their geodata via web services, eliminating shipping time and resources. All services are based on OGC standards e.g. WFS, WMTS, WMS and WCS. Furthermore the Digital Map Supply exposes a range of REST and SOAP services for geocoding, address searches etc. As part of the common public-sector eGOVERNMENT strategy 2011-2015, the government and Local Government Denmark have agreed on a basic data programme. The programme contains a number of specific improvements and initiatives in public-sector basic data, which will underpin greater efficiency and growth. The Digital Map Supply is the infrastructure that is used to supply the geospatial data to public agencies, end users, private companies etc. Furthermore the Digital Map Supply also supports a number of INSPIRE compliant services that The Geodata Agency is responsible of - such as a cadastral WFS. The presentation will show the architecture behind the Digital Map Supply including the number of open source components such as PostGIS, MapServer, GeoWebCache and GeoServer. The Digital Map Supply has been in service for more than ten years and the architecture has evolved during that time moving from commercial software to open source software. Moreover the presentation will outline the future of the Digital Map Supply including the migration to a new, common National distribution platform for all common public-sector data.

description: The importance of Open Source Geospatial Labs in widening Geospatial education worldwide Suchith Anand, University of Nottingham, UK Charlie Schweik, University of Massachusetts, Amherst, USA Helena Mitasova, North Carolina State University Maria Antonia Brovelli, Politecnico di Milano, Italy Serena Cotezee, University of Pretoria, South Africa Phil Davis, GeoTech Center, Delmar College, USA Patrick Hogan, NASA, USA Raphael Moreno, University of Colorado, Denver, USA Jeremy Morley, University of Nottingham, UK Although there has been tremendous growth in geospatial science over the last decade, the number of universities offering teaching in geospatial science in developing countries is very low. There are number of factors for this including high cost of software, lack of trained staff etc. But with the advent and maturity of free and open source geospatial software many universities in developing countries across the world will be establishing courses in geospatial science in the next few years. It was with this bigger mission in mind that in Sep 2011, the Open Source Geospatial Foundation (OSGeo) and the International Cartographic Association (ICA) signed an MoU with the aim of developing on a global basis collaboration opportunities for academia, industry and government organizations in open source GIS software and data. Within a span of one year, we now have established labs across the planet in 6 continents . We have now grown to 20 research labs across the world (6 in Europe, 3 in North America, 3 in South America, 4 in Asia, 3 in Africa and 1 in Australia). The three main aims of the ICA-OSGeo Lab Network are to provide expertise and support for the establishment of Open Source Geospatial Laboratories and Research Centers across the world for supporting development of open-source geospatial software technologies, training and expertise ; to provide support for building-up and supporting development of open source GIS training materials; to enable development of collaboration opportunities for academia, industry and government organizations in open source GIS for the purpose of creating a sustainable ecosystem for open source GIS globally. The availability of free and open source GIS will make possible for large number of universities especially in developing countries to also start courses in geospatial science. This will in true sense bring down the entry barrier for many students especially in developing countries to learn GIS. The OSGeo.orgs education and curriculum committee has a significant history of collaboration and established significant social capital among the network of participants. but up until now, we have only been able to achieve collaboration in the form of individual posts of metadata and links to educational material [2]. With the emergence of this lab network model, coupled with the right incentives, we are confident that this network can do more collectively on the education front, and we have not yet formed closer collaborative ties in the area of open geospatial application and research. Recently the authors listed above have been collaborating on a grant proposal to establish a new effort for this open geospatial lab network that mimics open source software collaboration and that includes three key components: (1) a coordinated teaching program; (2) a repository and a system for the management of new derivatives; and (3) a organized cross-node research program focusing on applications of open geospatial technologies to support local governance and management in several key environmental management areas. In this presentation, we will describe elements of this proposal, partly in an effort to encourage others at FOSS4G to consider joining in the effort, and to solicit other collaborative ideas from the audience.

description: The Tuscany Regional Administration had a rather usual proprietary GIS infrastructure (ArcIMS, Oracle, ArcGIS). They started migrating to Open Source GIS with an integrated approach, both on the sever side (PostGIS, MapServer, Geonetworks) and on the client side (Quantum GIS, GRASS), providing also training to hundreds of their technicians. What makes this experience particularly interesting is the fact that they worked form the onset in very close contact with the community, requiring that the code developed for them was generalized, and pushed to main source code. This seemed more cumbersome at first, having to coordinate with several other developers, and not having functions closely fit to their specific needs, but the superiority of this approach become quickly evident, as several functions were further improved and maintained by third parties. Among the most notable achievements were much improved topology support in PostGIS, SLD support in QGIS, and much more. We advise other administrations and enterprises to avoid the temptation of working in isolation, and simply using FOSS4G, maybe tailoring it locally, without contributing back, as this approach is short-lived, and less successful in the long term.

description: In 2013, a new service type joined the deegree family - the deegree Web Map Tile Service. This deegree service implements the OGC WMTS 1.0.0 specification and is going to be the OGC reference implementation for this specification. Both, the OGC WMTS test suite and deegree's candidate reference implementation have been developed within the OGC OWS-9 initiative. The intention for implementing WMTS was that deegree had no clear strategy to handle big raster data. As a result, one of the advantages of deegree WMTS is the performant handling of big raster data - such as aerial images - and providing it through a standard-compliant interface. Additionally there is advanced support for using other web services based on OGC WMS and WMTS such as GeoServer, GeoWebCache and Mapserver as datasource for deegree's tiling API, which is the underlying data access layer of the WMTS. As a key feature deegree is capable of proxying FeatureInfo output from those remote services. The presentation will give an overview about deegree WMTS and all its capabilities, especially regarding the interfaces with other OSGeo components.

description: OpenGIS Web Map Tiling Service (WMTS) is becoming the standard used for distributing raster maps to the web and mobile applications, cell-phones, tablets as well as desktop software. Practically all popular desktop GIS products now support this standard as well, including ESRI ArcGIS for Desktop, open-source Quantum GIS (qgis) and uDig, etc. The TileServer, a new open-source software project, is going to be demonstrated. It is able to serve maps from an ordinary web-hosting and provide an efficient OGC WMTS compliant map tile service for maps pre-rendered with MapTiler, MapTiler Cluster, GDAL2Tiles, TileMill or available in MBTiles format. The presentation will demonstrate compatibility with ArcGIS client and other desktop GIS software, with popular web APIs (such as Google Maps, MapBox, OpenLayers, Leaflet) and with mobile SDKs. We will show a complete workflow from a GeoTIFF file (Ordnance Survey OpenData) with custom spatial reference coordinate system (OSGB / EPSG:27700) to the online service (OGC WMTS) provided from an ordinary web-hosting. The software has been originally developed by Klokan Technologies GmbH (Switzerland) in cooperation with NOAA (The National Oceanic and Atmospheric Administration, USA) and it has been successfully used to expose detailed aerial photos during disaster relief actions, for example on the crisis response for Hurricane Sandy and Hurricane Isaac in 2012. The software was able to handle large demand from an ordinary in-house web server without any issues. The geodata were displayed in a web application for general public and provided to GIS clients for professional use - thanks to compatibility with ArcIMS. It can be easily used for serving base maps, aerial photos or any other raster geodata. It very easy to apply - just copy the project files to a PHP-enabled directory along with your map data containing metadata.json file. The online service can be easily protected with password or burned-in watermarks made during the geodata rendering. Tiles are served directly by Apache web server with mod_rewrite rules as static files and therefore are very fast and with correct HTTP caching headers. The web interface and XML metadata are delivered via PHP, because it allows deployment on large number of existing web servers including variety of free web hosting providers. There is no need to install any additional software on the webserver. The mapping data can be easily served in the standardized form from in-house web servers, or from practically any standard web-hosting provider (the cheap unlimited tariffs are applicable too), and from a private cloud. The same principle can be applied on an external content distribution network (Amazon S3 / CloudFront) to serve the geodata with higher speed and reliability by automatically caching it geographically closer to your online visitors, while still paying only a few cents per transferred gigabyte.

description: Big Data in the Earth sciences, the Tera- to Exabyte archives, mostly are made up from coverage data whereby the term "coverage", according to ISO and OGC, is defined as the digital representation of some space-time varying phenomenon. Common examples include 1-D sensor timeseries, 2-D remote sensing imagery, 3D x/y/t image timeseries and x/y/z geology data, and 4-D x/y/z/t atmosphere and ocean data. Analytics on such data requires on-demand processing of sometimes significant complexity, such as getting the Fourier transform of satellite images. As network bandwidth limits prohibit transfer of such Big Data it is indispensable to devise protocols allowing clients to task flexible and fast processing on the server. The EarthServer initiative, funded by EU FP7 eInfrastructures, unites 11 partners from computer and earth sciences to establish Big Earth Data Analytics. One key ingredient is flexibility for users to ask what they want, not impeded and complicated by system internals. The EarthServer answer to this is to use high-level query languages; these have proven tremendously successful on tabular and XML data, and we extend them with a central geo data structure, multi-dimensional arrays. A second key ingredient is scalability. Without any doubt, scalability ultimately can only be achieved through parallelization. In the past, parallelizing code has been done at compile time and usually with manual intervention. The EarthServer approach is to perform a semantic-based dynamic distribution of queries fragments based on networks optimization and further criteria. The EarthServer platform is comprised by rasdaman, an Array DBMS enabling efficient storage and retrieval of any-size, any-type multi-dimensional raster data. In the project, rasdaman is being extended with several functionality and scalability features, including: support for irregular grids and general meshes; in-situ retrieval (evaluation of database queries on existing archive structures, avoiding data import and, hence, duplication); the aforementioned distributed query processing. Additionally, Web clients for multi-dimensional data visualization are being established. Client/server interfaces are strictly based on OGC and W3C standards, in particular the Web Coverage Processing Service (WCPS) which defines a high-level raster query language. We present the EarthServer project with its vision and approaches, relate it to the current state of standardization, and demonstrate it by way of large-scale data centers and their services using rasdaman.

description: Twitter has developed over the past few years into a potent source of public opinion and comment. The service passed 500 million users in June 2012, collectively posting hundreds of millions of tweets each day, and several high-profile analyses of this data (such as the Twitter Political Index, which mapped sentiment across the US towards the 2012 presidential candidates over the course of their campaigns) have demonstrated its potential for insight and near-time customer feedback. Handling such large volumes and throughputs of data is a sizeable engineering challenge, however, and several commercial ventures (TweetReach, Tweet Archivist - many others) have sprung up specifically to deal with this complexity - at a cost. In addition, many existing solutions are unable to properly utilise the location data that is present in a significant proportion of tweets, losing out on the rich geographical context. This retrospective aims to demonstrate how an informed coupling of emerging open-source component technologies can be used to resolve the complex problems of i. large stored data volumes, ii. real-time streaming input, iii. concurrency of writes and iv. geographically querying and visualising results - with a minimal development outlay. Specifically, the construction of an open-source process to read, process, write, query and visualise streaming, geolocated Twitter data using the MongoDB NoSQL database and D3.js JavaScript library will be detailed, focusing on how MongoDB handles real-time spatial data (including spatial indexes & querying) and the unique features that make D3 so well-suited to visualising and exploring spatial data in the web browser.

In this presentation I show how the implementation of Spatial OLAP can give better insight in the quality of the construction of waterway banks. By spatially overlaying inspection results with construction records, a better estimation can be made about the overall quality, potential danger and repair costs. Spatial OLAP is an excellent way to provide insight into the different variables involved in the planning proces of maintenance.

VivaCity Smart City Platform

uk: Комп'ютерні науки

description: Many big vendors are exploring the smart city concept explaining that the smart city is a city aware of the things happening in the infrastructures. Thus the vendors are pushing for a Smart Grid, Smart Metering, Smart Sensors and Smart Whatsoever. This makes the city look like a sick patient, being monitored in many ways with histograms, gauges and panels for the information to be read. In our opinion this is the most unnatural way to interact with city information. Historically the most used way to interact with citizen oriented information is the map. Even today, with the always more precise GIS tools, the map can be an important part of a city information management tool. The VivaCity Project is a platform for the data-driven smart city. The core of the platform consists of a map- based view of the city itself, with all the possible cartographic open data made available by the governance. Beyond that, various apps can contribute in a smart manner through a set of plugins and entry-points for various views of the city, enabling a deep and complex interaction with the city itself. This system is self-sustaining, considering that the city already contains its monitors, which are the citizens. They just need two sets of tools: a visualization tool enabling the citizens to understand what is being done at a given time, and a tool to express opinions, problems and proposals to the governance. Considering that an overly generic tool loses its meaning because it has no real target, the interaction with the governance is delegated to function-specific or target-specific apps sharing a common API. This way both governance and citizen gain benefits, having both sides creating new data all the time and interconnecting information from the city and its inhabitants: governance has the ability make decisions based on real-time citizen-driven data, while citizens have the opportunity to create new services using the provided data. Figure 1 - Part of the VivaCity Smart City Interface For instance, the APIs offered to external apps are aimed to the following areas of interest: Politics, political decisions Maintenance Security City Info, Touristic, Cultural information Management, urbanistic information Urban events, Urban Acupuncture, social analysis Emergency Management, Emergency information aggregation from the many sources available Economic, Managerial information Environmental, Energy usage information The data shown in the interface is the sum and interpretation of the data provided by the local governments through open data, or applications created by third parties like OpenMunicipio in Italy, the OpenSpending platform by OKFN or even simply mash-ups with complex datasources, like the USGS earthquake map, or the various regional APIs for simple services or any other app enabling the citizen to participate actively to the activity of his government. Using the platform in different cities enables a normalization of the services offered by the cities, and the direct comparison and interconnection of cities through a distributed API supporting the governance to empower policies and improve citizens lifes.

description: Water quality is a major problem nowadays around the world. CLEANWATER system combine various information and complex data in order to evaluate the present level of nutrient pollution in vulnerable areas, as well as to assess the cost-efficiency of the measures that could be applied. Through a simple and intuitive web interface, CLEANWATER offers the decision makers a spatial aware tool to (1) create scenarios related to the human activities and climate changes, (2) send those scenarios to numerical models to model future evolution of water quality and (3) view, query and perform spatial analysis of the simulation results. The system was implemented in a test river basin (Barlad River Basin in Eastern part of Romanian) and started to contribute to the development of a modern water management system, according to EU legislation (e.g. Water Framework Directive, Nitrates Directive). The future plan is to replicate the system at national and international level. The system is build entirely with standard compliant free and open source software applications like OpenLayers, ExtJS, PostGIS, GeoServer and GDAL.

description: In April 2010, Ordnance Survey made a number of their national mapping products freely available under the OS OpenData initiative. Vector and raster datasets at varying scales were released under a very permissive license which allows users to freely create derivative works, even for commercial purposes. Lutra Consulting released a WebGIS application to demonstrate the value and potential of combining OS OpenData, OGC services & standards and open source GIS software. The WebGIS application, Catchment Finder, uses the OGC Web Processing Service (WPS) to provide a simple method for users to generate hydrological catchments (or watersheds) for any point in the UK. Catchment delineation is based on the OpenData Landform PANORAMA dataset, a 50 metre resolution digital terrain model (DTM). Catchment Finder was developed using the following FOSS components: OpenLayers and Ext JS for all user-facing functionality. MapServer and TileCache to serve background mapping and processed results. GRASS GIS for server-side catchment delineation process. PyWPS to provide a mechanism for interaction between the browser and GIS processing taking place on the server. GRASS GIS sits at the core of Catchment Finder. National slope and aspect raster datasets were pre-calculated as inputs for the watershed analysis module in order to optimise calculation times. A WPS process was developed in python (using PyWPS and GRASS python bindings). The process chains together a number of GRASS commands in order to generate a vector layer representing the catchment outline which is then displayed in the web client via GML or optionally downloaded as a Shapefile. PyWPS (based on python) was chosen in preference to alternative WPS server implementations due to the typical flexibility and efficiency offered by python (a high-level programming language). Implementing specific GIS processing tasks as WebGIS applications simplifies the end-users tasks and therefore opens up GIS processes to non-technical people. Storing datasets and carrying out processing centrally helps remove the burden of managing large/national datasets. Any updates to underlying datasets can be carried out centrally with minimal impact. As Catchment Finder implements the OGC WPS standard, it is also possible for the service to be utilised by desktop GIS applications. At present, due to the low resolution of the underlying DTM, it is only possible to generate watersheds for larger watercourses.

description: Driven by the rise of Web 2.0 and the non-stop spread of mobile device sensors, the concept of PGIS (Participatory GIS) is knowing a new, revolutionary era. This research investigates the opportunity to build up a prototype of Participatory GIS, with completely FOSS architecture, in which data directly comes from field surveys carried out by users. As a result, the system should increase public active participation in data creation and sharing, besides enlarging the knowledge up to the local level. Open Data Kit suite allows users to collect geotagged multimedia information using mobile devices with on-board location sensors (e.g. a GPS receiver). Thanks to an authentication mechanism, on field-captured data is sent to a server and stored into a PostgreSQL database with PostGIS spatial extension. GeoServer is then responsible for data dissemination on the Web. On the client- side, different OpenLayers and Leaflet based solutions allow data visualization on both traditional computers and mobile platforms. The designed architecture provided support for FOSS usage in the process of gathering, uploading and WMS/WFS publishing information collected in situ. GIS user participation could thus be substantially increased, making this innovative bottom-up approach a key factor for fostering, speeding and improving decision-processes.

description: "Open Standards, Open Source, Open Data: Zuviel des Guten?" - Der Vortrag beleuchtet ausnahmsweise mal die Schattenseiten dieser drei Gesellen, denn: Ja, es gibt sie, z.B. * behindern Standards Innovation, * zerstört Open Source bewährte Geschäftsmodelle und * Open Data fördert das Chaos. Eine konstruktive Herangehensweise zeigt, dass es lediglich gilt diese Schattenseiten auzuleuchten, um das volle Potential expliziter Offenheit ausschöpfen zu können. == Open Standards == Ein Blick auf das Alter einiger Standards und deren Praktibilität in der heutigen IT-Landschaft zeigt, wie schwer es ist Innovation einzuführen. Und das ist auch gut so, denn nicht jede Innovation ist auch gleich gut. Oft sind Innovationen auch einfach nur neu und vollkommen überflüssig oder müssen Bewährtes gar nicht zwingend ersetzen, sondern können es ergänzen. Der Beitrag stellt Möglichkeiten vor, Innovation in geregelter Form einzubringen. == Open Source == Open Source zerstört proprietäre Geschäftsmodelle und ist deshalb ein Verlust für herkömmliche Softwarehersteller die sich weigern ihr Geschäftsmodell an veränderte Bedingungen anzupassen. Open Source führt aber auch zu Innovation, belebt den Markt und fördert den Wettbewerb. Lediglich 10% des Umsatzes in IT Projekten basiert auf proprietären Geschäftsmodellen. == Open Data == Der Begriff Open Data ist noch nicht klar definiert und bedarf zusätzlicher Erkläuterungen. Die wachsende Verfügbarkeit von Open Data wirft eine ganze Reihe neuer und alter Fragen auf, die hier vorgestellt werden. Es gilt transparente Antworten auf diese Fragen zu finden um die Daten und den Umgang damit kontinuierlich verbessern zu können. Innovation fordert kontinuierliche Investition. Das geht besser, wenn alle Aktuere (Stakeholder) an den Prozessen teilnehmen können und nicht, wie es bisher oft der Fall war, alles geheim und hinter verschlossenen Türen entschieden wird. Im Grunde stimmt es also doch: Alles offen, alles gut. Man muss nur wissen wie.

description: Das Projekt OSGeo-Live gewährt einen umfassenden Überblick über freie und offene GIS-Software und GeoDaten OSGeo-Live ist ein OpenSource-Projekt, das mehr als 50 Softwareprojekte aus dem Bereich FOSS+GIS bündelt. Sie finden Projekte aus den Bereichen Web Mapping Clients und Server, DesktopGIS, Datenbanken, Krisenmanagement, Navigation und Karten sowie räumliche Tools. Die OSGeo-Live ist somit ein sehr gutes Beispiel für ein erfolgreiches OpenSource-Projekt. Dabei handelt es sich nicht um ein klassisches Software-Projekt, sondern um eine Zusammenstellung verschiedenster Anwendungen und Informationen, die dem interessierten Publikum als gut sortierte Werkzeugkiste angeboten wird. Projektübergreifend wurden viele Freiwillige gefunden, die regelmäßig die Inhalte aktualisieren. Damit ist ein Produkt entstanden, was als globale Visitenkarte nicht nur der OSGeo-Projekte dient. OSGe-Live kann in Workshops und eigenen Veranstaltungen verwendet werden. Alle FOSS- und GIS-relevante Software wird mehrsprachig und mit Dokumentation zur Verfügung gestellt. So ligen beispielsweise Übersetzungen ins Deutsche, Italienische, Polnische, Griechische, Japanische, Französiche, Catalanische, Chinesiche, Koreanische vor. Dieser Vortrag liefert Einblicke in die Entstehung und den Aufbau dieses Projektes. Die ehrgeizigen Ziele wie mehrsprachige Dokumentation, Benutzung von Beispieldatensätzen und Support in der Community stellen ganz unterschiedliche Anforderungen. Es gilt nicht nur technische Probleme zu lösen. Hinzu kommen terminliche Absprachen, damit zu bestimmten Anlässen wie wichtigen Konferenzen und Workshops aktuelle Versionen bereit stehen. =FOSSGIS= Auch auf der **FOSSGIS Konferenz 2013** kommt die OSGeo-Live in den Workshops zum Einsatz und wird als DVD an die Teilnehmer der Konferenz verteilt.
