Geoservices, also known as geodata services or OpenGIS Web Services (OWS), are networkable, spatial web services that make geodata accessible in a structured form. Geoservices play a central role in a geodata infrastructure because they are the link to the geodata in their numerous data models and formats. It is only through the use of geoservices that interoperable use for a wide range of network-based geo applications and geoinformation systems (GIS) is possible.

OGC Web Services (WMS, WFS, INSPIRE View Service, INSPIRE Download Services)

OGC web services are standardized geodata services. Standardization is carried out using the technical documents of the Open Geospatial Consortium (OGC). These specifications are in turn based on the ISO 19100 series of standards, processed by ISO TC 211.

State administration data can be used via the following (fee-based) services:

• WFS, Web Feature Service
• Web Map Service, tiled as Web Map Tile Service WMTS

The Office for Civil Engineering and Geoinformation offers a freely accessible test service for testing purposes. You can find the test service here

Transformation services

Transformation services are services that make it possible to transform geodata to specific formats, specific data models or specific reference frames and thus make them usable for your own applications. For coordinate transformation, the Office of Civil Engineering and Geoinformation works together with the Federal Office of Topography. You can also transform data with Liechenstein coordinates using the swisstopo online calculation service

Check and validation services

Check or validation services are Internet services that can be used to check data sets for conformity with data models and standards.

- Check service of the official cadastral survey

The Office of Civil Engineering and Geoinformation operates a check service for official cadastral surveying data. This service is used to check whether the specified structure and the conditions defined in the associated data model DM.01 are complied with for the respective dataset.

Checks carried out are, for example

• Do the plots map the perimeter of the municipality, without overlaps and without holes
• Has an address been assigned to an area that is not a building?
• Are all plots labeled on the plan
