Web Map Service (WMS)

Federal offices make part of their data available via the WMS - Federal Spatial Data Infrastructure (FSDI) service. The data layers currently available in the WMS-FSDI correspond, with a few exceptions, to the geodata that are presented in map.geo.admin.ch.

GetCapabilities

The GetCapabilities document provides information about the service, along with layer description, both in German and French.
