 Nota bene: Please, do not use the `tms-global-geodetic` reference frame for anything else than terrain provider support. This reference frame is absolutely inappropriate for the VTS system because the underlying [projection (eqc)](https://en.wikipedia.org/wiki/Equirectangular_projection) is neither equal area nor [conformal](https://en.wikipedia.org/wiki/Conformal_map_projection). 
 
-However, the only other use the `tms-global-geodetic` reference frame in VTS is the `tms` driver when generating data for [Cesium Imagery Provider](https://cesiumjs.org/Cesium/Build/Documentation/ImageryProvider.html); bear in mind that that there is no extra imagery provider interface and the URL translation must be done in the javascript driver. Introspection interface does it automatically, though.
