From 2000, the IGN develops the concept of Reference frame on a Large Scale (référentiel à grande échelle = RGE); it is a question of completing within a deadline short digitalization the cartography of the French territory with a meter scale and according to four components: topography, land registry and address. This RGE is entirely completed at the end of 2008. Then it enter in a cycle of maintenance in June 2006, the IGN opened the service Géoportail allowing the cartographic visualization of the French territory on a Web navigator and using on one hand funds of air photographs and on the other hand the digitized maps to the 1/25 000. "Phase 2" of Géoportail was put on line one year later, with a new ergonomics.
