Paper Abstract (long) 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. Topic type Target Type Visualization: effective presentation of People new to open source geospatial information.

I can give a practical demo yes Paper Abstract (short) The aim of this talk is to sum up the standardization efforts (OGC and W3C) in defining 3D web services and models, as well as to show existing implementations to support the discussion. Paper Abstract (long) In the past years, numerous open source projects have started to display 3D globes and 3D data on the web. Standardizing web services, data format and representation models is, therefore, a very hot topic. There are in particular ongoing efforts on the OGC side as well as on the W3C side. The OGC has released a draft candidate for a 3D web service W3DS, the ISO X3D standard proposes an XML- based file format for representing 3D computer graphics and the W3C is considering adding X3D rendering into HTML5. Other projects implement their own web services and formats. On the implementation side, Geoserver supports W3DS and X3D, the X3DOM library prototypes a possible implementation of X3D HTML5 integration and last but not least, browsers with WebGL support are fully able to handle the representation of 3D data on the client side. The talk is going to detail the mentioned elements, show demonstrations of existing implementations and try to suggest a possible path into the 3D web for the FOSS4G community.

The advantages offered by R as a development environment for a CA land use model are evaluated, and the pros and cons of the approach employed are discussed in depth with reference to commercial alternatives. Paper Abstract (long) The application of geographic Cellular Automata (CA) based techniques for land use modelling can be traced back to the theoretical formulations of the American geographer Tobler (1979), later implemented in practice by White and Englelen (1993) and Batty and Xie (1994). Since then, CA applications have developed very rapidly and CA-based software environments such as Metronamica and SLEUTH are now widely employed in many countries across several continents as scientific and policy tools for exploring land use dynamics and future land use change. The term CA is sometimes applied in a broad sense to any cell-based land use model in which algorithmic operations are used iteratively to determine future land use states on the basis of parameters such as distance from transport networks (accessibility), biophysical aptitude of land areas to take on new states (suitability), or exclusion zones such as natural protected areas or land set aside for future development (zoning). However, in a a CA land use model sensu stricto, key land use change dynamics are represented by neighbourhood transition functions, in which the value (land use class) of a given cell in each model iteration is determined by the value of adjacent cells according to user- defined attraction or repulsion parameters, with accessibility, suitability and zoning being applied to support new land use allocation. Determinism is avoided and realistic human behaviour is imitated by applying stochastic perturbations to the model derived from probability distributions. Simple initial cell states transformed in this way through many model runs can give rise to patterns of great complexity, chaotic structure and, eventually, randomness. This key distinction, that is, autonomy and capacity to self-organize, is what gives true CA models their power to replicate artificial processes such as urban development with a high degree of success. Though there are a number of Free and Open Source Software (FOSS) applications presently available for other types of land use models, such as Huang's Change Analysis (logistic regression), and Purdue University's Land Transformation Modeller (LTM) (Artificial Neural Networks), there are few fully operational implementations of true CA models for land use modelling in the Open Source community. In addition, stand alone model frameworks do not usually incorporate appropriate statistical goodness-of-fit comparison techniques for model evaluation, something that is normally carried out externally in statistical software packages. In this paper, we discuss in detail our recent work to address these limitations by developing and testing a CA land use model for the R software environment. The R platform, with its extensive developer and user community, and its clear relevance for model building and scientific computing, seems to present an ideal environment for geographical land use modelling. The advantages offered by R as a development environment for a CA land use model are evaluated, and the pros and cons of the approach employed are discussed in depth with reference to commercial alternatives.

As an example an application will be presented that integrates sensor data with data from an existing spatial data infrastructure. Paper Abstract (long) The Sensor Web Enablement (SWE) of framework has been around for almost ten years. The goal of the SWE is to enable the integration of sensors and sensor data into existing spatial data infrastructures. This presentation will look at in what extent this goal of the SWE framework has been achieved. Besides presenting the current state of SWE also a future perspective will presented. This future perspective is based on a series of interview with leading organizations in the adaption and usage of SWE standards in the Netherlands. From this future perspective, potential use cases will be presented for the integration of sensor data with existing spatial data infrastructures. One of these use cases will be presented as a functional open source application. Topic type Target Type Case Studies: Relate your experiences.

Paper Abstract (long) Talking about 3D used to sound cool. Used to. But for real GIS use, we really need more than just playing with a globe. 3D in GIS becomes cool as soon as we have the ability to deal with full 3D spatial analysis. Just as we already have in 2D, we need functions like intersection, buffer, triangulation and more ... The GEOS library provides us 2D topological processing for years. The CGAL library could now also provide us some interesting additional 3D topological functions. As CGAL is not fully designed for GIS data models, we provide a library inbetween called SFCGAL, in charge of providing a Simple Feature API on top of CGAL. PostGIS 2.1 now allows to link PostGIS and (SF)CGAL, and already provides several exciting 3D functions (and more and more to come). This thrilling talk about PostGIS 3D will therefore focus on : - What kind of project / application needs 3D GIS analysis ? - What can we do right now with PostGIS 2.1 and (SF)CGAL ? - What we will be able to do soon with PostGIS 3D ? - Some tools used to view and manipulate 3D data (QGIS / WebGL based) Topic type Target Type Development: new developments in products.

Paper Abstract (long) European Union (EU) Member States are currently in the implementation phase of the INSPIRE Directive, building a cross-border spatial data infrastructure (SDI) for Europe by adding components to their existing spatial data-sharing resources. Although INSPIREÕs technical guidelines have been based on existing international standards, implementations often use standards either in different ways or different versions. In addition, standards themselves regularly evolve with often limited coordination between changes in different standards. Such issues can limit interoperability between information systems, especially in cross-border contexts. There is a need for additional guidance and increased collaboration to share best practices and approaches in INSPIREÕs implementation. Moreover, technical components (software, technical guidelines, Ôsemantic assetsÕ etc.) need to be referenced and shared to support the EU Member States and address these interoperability issues. Such a resource will also help other European policy areas to reuse this material when looking to share and integrate spatial in their, broadly speaking, e-government activities. This includes contributing to technologies and infrastructures to support open data and the EUÕs key ICT policy, the Digital Agenda for Europe. The EUÕs Interoperability Solutions for European Public Administrations (ISA) Programme is an initiative covering many aspects of the interoperability requirements for cross-border and cross- sector e-government, from strategic policy needs in legal and organisational interoperability through to semantic and technical requirements. Under ISA, a Reusable INSPIRE Reference Platform (ARE3NA) is addressing the dual needs to support interoperability between Member StatesÕ implementations and the reuse of INSPIRE components in other sectors. Based in the Unit responsible for the technical coordination of INSPIRE at the European CommissionÕs (EC) Joint Research Centre (JRC), the ARE3NA team have already established several baseline inventories as part of its initial evidence base. This includes an inventory of European policies using spatial information and a related inventory of data- sharing platforms and tools. Another inventory has reviewed recent studies to identifying components already being used in Member States, including associated architecture documents and the technologies being used in some INSPIRE implementation tasks. These have, in turn helped to draft generic workflows in the INSPIRE implementation process. In many instances the tools being used are Free and Open Source Software (FOSS), and a third inventory has both built on the recent work of Steiniger and Hunter (2012) to create an overview of the current groups of technologies being deployed in Member States to support INSPIRE. In order to provide more reference components, work has also created inventories of the standards being used in INSPIRE, with a final inventory providing a baseline position on the amount of geospatial data current being shared in national open data portals. The online ARE3NA platform space to share these findings has recently been established within the ISA programmeÕs JoinUp platform, a resource to support developers and e-government professionals share their experience with interoperability solutions. This platform will help users to validate the material being found and to gather further examples towards a ÔconstellationÕ of components connected to INSPIREÕs legal items, implementation tasks and the technologies (etc.) involved. The platform is being supported by a survey to gather further evidence that will run for the duration of the project. The survey aims to establish what other technologies are being used to support INSPIRE implementation and where there may be Ômissing componentsÕ or gaps in current technologies or standards or, similarly, gaps between the data-sharing infrastructure of INSPIRE and the needs of European cross-border and cross-sector e-government, including those that ARE3NA can help to address by supporting developments in new or existing open source projects. The survey also aims to identify good practices and training to support INSPIRE implementation across the Member States in the coming years. Already, ARE3NA has addressed one gap by developing the open source INSPIRE Registry. This fundamental component for geospatial data interoperability across European SDIs provides a means to manage and share codelists from INSPIRE data models. By developing the INSPIRE Registry with ISA in mind, these codes can also be readily adopted in other contexts, potentially reducing multiple vocabularies for similar spatial objects across Europe. By basing its development on open source software tools, the INSPIRE Registry itself becomes a reusable component in JoinUp, so that other interoperability projects can adopt the software for their own purposes, including any register, including those involving hierarchical information, from organogram details to thesauri. Following the collaborative processes seen throughout INSPIRE, the presentation will provide an opportunity to introduce ARE3NA to a key stakeholder audience, with an invitation to participate in the platform and survey as well as present the evidence to date, illustrating the role of FOSS in establishing interoperable SDIs in Europe.

Technical / Developer ID Number 183 Name Michelle Walker Organisation The Rivers Trust Email [email protected] Paper Title A toe in the water - using open source software to support catchment management planning I can give a practical demo yes Paper Abstract (short) The Rivers Trust demonstrate how open source software and data is improving the sharing of information, leading to better decision-making and ultimately more sustainable management of rivers and their catchments. Paper Abstract (long) Integrated river catchment management planning seeks to balance many demands on the water and land, to protect water resources and ecology for the benefit of the economy, society and the natural world. Third sector organisations have a key role in this process - providing both the practical delivery of river restoration work, and an 'honest broker' role between government, private sector interests and local communities, to try and balance these often conflicting interests in a sustainable catchment plan. However, access to the complex evidence, software models and datasets, which are required for strategic environmental management planning, can be difficult for the third sector and community groups, due to reasons such as cost, licensing restrictions or technical capability. As the umbrella organisation of the rivers trusts movement in England, Wales and Northern Ireland, The Rivers Trust has been exploring the potential for open source software and datasets to improve the sharing of information and evidence with a range of stakeholders in the catchment management planning process. A web GIS application for identifying and prioritising barriers to migratory fish (based on Geoserver) and an application to identify sources of diffuse sediment pollution (built on SAGA GIS) will be demonstrated, and plans for future development of open source tools and data sharing is discussed.

Paper Abstract (long) Various software can style maps and generate a proper SLD document for OGC compliant WMS like GeoServer to use. However, in most occasions, the styling allowed by the graphical tools is pretty limited and not good enough to achieve good looking, readable and efficient cartographic output. Topics that will be covered are as follows: - Mastering multi-scale styling, choosing the appropriate style and content for the various map scales - Using GeoServer extensions to build common hatch patterns - Line styling beyond the basics, such as cased lines, controlling symbols along a line and the way they repeat - Leveraging TTF symbol fonts and SVGs to generate good looking point thematic maps, line and fill patterns - Use the full power of GeoServer label lay-outing tools to build pleasant, informative maps on both point, polygon and line layers, including adding road plates to your map - Leverage the labelling subsystem conflict resolution engine to avoid overlaps in stand alone point symbology - Blending charts into a map - Dynamically transform data during rendering to get more explicative maps without the need to pre-process a large amount of views, such as on the fly contours extraction, heat maps, and wind maps from raster data - Leverage the analitic power of spatial databases to build dynamic thematic maps based on SQL views - Perform cross layer filtering and parametrize it to perform informative cross layer containment and neighborhood searches. The presentation aims to provide the attendees with enough information to master SLD documents allowing him to produce amazingly looking maps on his own. At the end of the presentation the SLD will no longer be cartographer's enemy. Topic type Target Type Case Studies: Relate your experiences.
