Coordinates Reference Systems

Geoportal's API supports coordinates reference systems as defined in OGC standards. One can find some EPSG codes as well as IGN's own CRS catalogue. This later catalogue gives the mapping, whenever it exists, between IGNF codes and EPSG codes.

Coordinates reference systems depend upon territory and accessed services (by default, mouse positions are can be rendered in any of the following coordinates reference systems except when contrarily written). Main coordinates reference systems are :
