Height Models

swissALTI3D is an extremely precise digital elevation model which describes the surface of Switzerland without vegetation and development. It is updated every six years.

swissSURFACE3D models all natural and man-made objects of the surface of Switzerland in the form of a classified point cloud. These high-accuracy and high spatial density data are collected by airborne LiDAR.

swissSURFACE3D Raster is a digital surface model (DSM) which represents the earth’s surface including visible and permanent landscape elements such as soil, natural cover, and all sorts of constructive work with the exception of power lines and masts.

swissBATHY3D contains bathymetric data in the form of a very accurate digital elevation model that describes the topography of the Swiss lakebeds.

swissALTIRegio is a small scale digital height model that describes the surface without vegetation nor construction of Switzerland and regions of its neighbouring countries.

Digital height model DHM25 is a set of data representing the 3D form of the earth’s surface without vegetation and buildings. It is essentially based on the 1:25'000 Swiss national map.

Digital height model DHM25 with 200 m grid is a set of data representing the 3D form of the earth’s surface without vegetation and buildings. It is essentially based on the 1:25'000 Swiss national map.
