swissTLM3D Hydrographical network

swissTLM3D hydrographical network contains the watercourses and lake contours of Switzerland and the Principality of Liechtenstein. It is part of the dataset swissTLM3D. With a high accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive 3D vector data set of Switzerland.

Maintenance and update frequency
Annually
Maintenance note

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, buildings 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.
