swissTLM3D
swissTLM3D is the large-scale topographical landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector data set of Switzerland.

The existing data was migrated into the TLM as a basis. The data is now updated based on an update cycle of 3 years and improvements and additions are made to the geometries and attributes. Parallel to the three-year update process, an annual update is carried out through the integration of data from so-called reference partners for selected topics. Initially, this annual update is implemented mainly for the administrative boundaries and road links. The official cadastral survey plays an important role as a reference partner in this process. The nomenclature for updating names are also integrated from the official cadastral survey.
