Yesterday in the late afternoon the Swiss Federal Office of Topography (Swisstopo) declared (German) the exposure of maps via web service and opening up of their API (press release also only in German) through Swisstopo web access (brief description in English) with the following two options:
- WMTS option (Web Map Tile Service):
This service lets you display current geodata (aerial imagery at 25 and 50 cm resolution, national maps at all scales and historic Dufour and Siegfried maps; see list) from Swisstopo. Up to a certain amount of served data, the service is free. If necessary, the quota can be enlarged by paying a fee. More details in English can be gleaned from the product sheet.
- API option called GeoAdmin:
For easier integration of maps into your website, additional functionality and more data. Using the API requires you to first sign up with Swisstopo. There is extensive documentation of the API as well as a Google Group.
This is certainly thrilling and revolutionary for anybody working with Swiss geodata. I would say, nobody would have predicted this move some years ago.
