DHM25 basis model
The digital height model DHM25 is a data set representing the three-dimensional form of the earth?s surface. It was derived from the height information of the Swiss National Map 1:25'000 and 1:50'000 -for the extended perimeter.The base model contains the following elements: linear elements: vectorized contours and contours in lakes, vectorized lake perimeters, primary breaklines; dot elements: digitized spot heights and depth spot heights in lakes. The DHM25 represents the topography of the earth's surface without vegetation or built up areas.

The status of the DHM25 corresponds to that of the initial capture and digitization of the elements for the basis model except for glacial regions, which were updated in winter 2000/2001.
