Web Mapping Services WMS: Available services an data
The BGDI supports the federal offices by setting up WMS services. You can freely use the following examples and integrate them into any GIS system.
Federal offices make part of their data available via the WMS-FSDI service. Users of geographic information systems (GIS) can integrate these services into their software using the service's metadata (Capabilities).
The data layers currently available in the WMS-FSDI correspond, with a few exceptions, to the geodata that are also presented in map.geo.admin.ch. The WMS-FSDI can be used free of charge and provides access to public geodata. The requests GetCapabilities, GetMap, GetFeatureInfo and GetLegendGraphic are supported.
The WMS-FSDI is accessible via a secure connection. The URL is https://wms.geo.admin.ch/.
In most geographic information systems, specifying the above URL is sufficient for using the data. Otherwise, the GetCapabilities request is: https://wms.geo.admin.ch/?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities
(the choice of the language [de,fr,it,en] is done by adding the parameterlang=en)
Example of a GetMap request:
https://wms.geo.admin.ch/?SERVICE=WMS&REQUEST=GetMap&VERSION=1.3.0&LAYERS=ch.bafu.bundesinventare-bln&STYLES=default&CRS=EPSG:2056&BBOX=2550000,1060000,2660000,1140000&WIDTH=800&HEIGHT=582&FORMAT=image/png
Example of a GetFeatureInfo request:
https://wms.geo.admin.ch/?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&FORMAT=image%2Fpng&TRANSPARENT=true&QUERY_LAYERS=ch.bafu.bundesinventare-bln&LAYERS=ch.bafu.bundesinventare-bln&FEATURE_COUNT=10&INFO_FORMAT=text%2Fplain&LANG=en&I=50&J=50&CRS=EPSG%3A2056&STYLES=&WIDTH=101&HEIGHT=101&BBOX=2609000%2C1123050%2C2614050%2C1128100
(the choice of the language [de,fr,it,en] is done by adding the parameter lang=en)
Example of a GetLegendGraphic request:
https://wms.geo.admin.ch/?SERVICE=WMS&REQUEST=GetLegendGraphic&VERSION=1.3.0&LAYERS=ch.bafu.bundesinventare-bln&STYLES=default&LANG=en&CRS=EPSG:2056&BBOX=2550000,1060000,2660000,1140000&WIDTH=800&HEIGHT=582&FORMAT=image/png

Intended use
Web Map Services are especially interesting if you want to use continuously updated geodata in a predefined representation. Internet access is mandatory.
