GI STANDARDS APPROACH IN THE FRENCH GÉOPORTAIL 23/06/2014 XX 4/

THE FRENCH GÉOPORTAIL  ONLINE ACCESS TO PUBLIC DATASETS THROUGH STANDARDISED GEOGRAPHIC 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 23/06/20145/17

FUNCTIONAL ARCHITECTURE 23/06/20146/17

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 23/06/20147/17

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 23/06/20148/17

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 23/06/20149/17

VECTOR DATA MAP SERVICE => DATABASE IN DISSEMINATION SCHEMA => LAYER AGGREGATION TO PROVIDE MULTI-SCALES & MULTI- PRODUCTS THEMES 23/06/2014 PostgreSQL 500 Gb of data 10 x 2 core server Nginx WMS ServiceWFS Service HTTP Server / Load Balancer DataBase Server (SFSQL compliant) 10/17

RASTER DATA MAP SERVICE => AD-HOC PYRAMID OF IMAGES, PREPARED FOR WMS => SPECIFIC DIRECTORY STRUCTURE => LARGE SIZE FILE : 4096X4096, INNERLY TILED (256X256) 23/06/ Tbytes of images Nginx WMS ServiceWMTS Service HTTP Server / Load Balancer File System 8x2 & 8x4 core server 11/17

CONCLUSIONS  INSPIRE PERFORMANCE REQUIREMENTS ARE MET  UPCOMING CHALLENGES :  Full WFS implementation  Support of INSPIRE schemas  Multilingualism  INSPIRE approach vs OGC approach 23/06/201413/17

RESULTS & PERSPECTIVES 23/06/201414/

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 23/06/201415/17

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,…) 23/06/201416/17
