With WMTS services in Cesium 1.1, the French national mapping agency (IGN) displays its geographical and topographical maps on a Cesium globe.

The Geoportail platform is the spatial data infrastructure that IGN has built to allow access to the French reference data through WMS, WMTS or other standard web services. The Geoportail JavaScript API facilitates access to those services and can be combined with the Cesium API, as shown below.
