Height Models

Height models are digital data sets which show the form of the earth's surface in 3D. Each set of X and Y coordinates shows a height (Z). Different products are available for various applications.


Example of swissALTI3D

swissALTI3D is a very precise digital elevation model which describes the surface of Switzerland and the Principality of Liechtenstein without vegetation and development. It is updated in an update cycle of 6 years.


Example of DOM

High precision height models based on a density of 0.5 points per m², established by airborne laser scanning (accuracy 0.5 to 1.5 m) are covering Switzerland below 2000 m.


Example of DHM25

This detailed height model is based on the Swiss National Map 1:25 000 (precision 1.5 to 10 m), with grids of 25 m and 200 m. It extends over the whole of Switzerland and adjacent areas.
