Digital Elevation Models

A digital elevation model (DEM) is a three-dimensional representation of a terrain's surface created from terrain elevation data.

Here you can find all the available years and the available formats for each service.

swissALTI3D (DTM)

swissALTI3D is an extremely precise digital elevation model which describes the surface of Switzerland without vegetation and development. It is updated in an cycle of 6 years. The derived dataset refers to DTM.
