  1. the French Geoportal GI Standards Approach

  2. GI Standards Approach in the French Géoportail XX

  3. The French Géoportailhttp://www.geoportail.gouv.fr • Online access to public datasets through Standardisedgeographic service interfaces • Citizen oriented • Show & overlay reference/partners datasets • Datasets • Easy and secured access to up-to-date overlayable data layers • Data type : topo, geological, relief & buildings, coastal, maritime • Multi-scale, multi-product

  4. Functional architecture

  5. Rok4 WMTS/WMS services • Initial challenge • One data, two services • Implement WMTS • IGNF solution : Rok4 • Be4 tools to prepare data • Rok4 WMTS to serve tiles • Rok4 WMS to serve images • For WMTS/WMS Raster and WMTS rastered vector

  6. Geoserver WMS/WFS services • Initial challenge • Meet INSPIRE performance requirements • 20 requests / seconds : 800x600 image (gif/png) • Two architectures • Vector data service • Efficient portrayal process • Raster data service • Fast serving of images

  7. Deegree WFS INSPIRE services • Initial challenge • Meet INSPIRE data schema • Database to store data in several tables per thematic • A Mapping file to generate INSPIRE compliant GML

  8. Vector data map service => Database in dissemination schema => Layer aggregation to provide multi-scales & multi-products themes HTTP Server / Load Balancer Nginx WMS 1.3.0 Service WFS 2.0.0 Service 10 x 2 core server PostgreSQL 500 Gb of data DataBase Server (SFSQL compliant)

  9. Raster data map service => Ad-hoc pyramid of images, prepared for WMS => Specific directory structure => Large size file : 4096x4096, innerly tiled (256x256) HTTP Server / Load Balancer Nginx WMS 1.3.0 Service WMTS 1.0.0 Service 8x2 & 8x4 core server File System 50 Tbytes of images

  10. ISO 19115/19119 Service Metadata Dataset Metadata OGC WMS GetCapabilities GetMap Co-Visualisation <fileIdentifier> Géoportail Co-Visualisation Géocatalogue OGC CSW ISO AP GetRecords (cache) GetRecordById (fileIdentifier) Service Providers

  11. Conclusions • INSPIRE performance requirements are met • Upcoming challenges : • Full WFS implementation • Support of INSPIRE schemas • Multilingualism • INSPIRE approach vs OGC approach

  12. Results & Perspectives

  13. Results • Standards are essential in the implementation of a SDI, with many partners involved • Some refinements needed • Performances • Full interoperability • More pragmatic implementation and best pratices

  14. Perspectives • Géoportail 3 planned evolutions • Go beyond WMS, in conformance with INSPIRE : WFS, WCS, possibly Transformation Services, … • Other ideas • Thematic maps using GeoLinking Service • Integration of sensor streams using SWE • Implementation of OPENLS Route and Navigation Services • Geocatalogue 2.5 planned evolutions • Ful INSPIRE compliance • INSPIRE reporting tools • Search API (openSearch,…)
