Web Map Tiling Services WMTS: available services and data
A WMTS service does not offer the flexibility of free scale selection; it offers instead faster loading/transmission time by using static tiles with fixed and discrete scales. This fixed structure of tiles allows the use of a WMTS service with a web server that simply retrieves the available files. This tile architecture also allows the use of standard network mechanisms for scalability such as distributed cache systems.
The WMTS-FSDI offers the WMTS maps available in map.geo.admin.ch. The WMTS-FSDI can be used free of charge. The requests GetCapabilities and GetTile are supported.
The WMTS-FSDI is accessible via a secure connection.
In some geographic information systems (GIS) the URL https://wmts.geo.admin.ch is sufficient to use the service. Otherwise the GetCapabilities request is:

Web Map Tile Services are tiled raster data, where pre-tiling reduces loading times. WMTS data is used when a constantly updated background is required.
