IGN produces and offers a wide range of map data products from raster data (images) to vector format data or even 3D data. Low detailed maps are available as open data, together with some specific layers such as administrative boundaries. For instance, raster maps are available as open data at 1:100000 scale. However, map with key infrastructure in vector format is not available as open data but can be obtained against a license fee. IGN also give access to some of its data through a Web Map Service (WMS).
