swissALTIRegio

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

The small-scale height model of Switzerland

Applications

swissALTI^Regio can be used in a large variety of applications:

• as a basic height data-set in a geographic information system
• as a basis for 3D visualisations over large areas
• as a basis for simulations and calculations over large areas
• in applications that go beyond the Swiss border
• As a basis for publications - e.g. as a background layer in maps, plans and web applications

Additional information

• Technical details

  Structure: The data are delivered as a grid with a cellsize of 10m. The data are delivered as a complete dataset (COG) or as complete 100 km² tiles(.xyz). The spatial density of the original data is not always high enough to derive a cellsize of 10 metres. It  is the case for the areas in Baden-Württemberg, the French Alps and certain regions of Italy. Oversampling" is carried out here. Coarser resolution data is interpolated so that the cellsize of 10 metres is achieved.

  Resolution: 10 metres

  Format and file size

  • Cloud Optimized Geotiff (COG), LZW-copression
    ~ 12 GB / complete coverage
  • ASCII X,Y,Zsingle space
    ~ 23 MB / tile, a total of  ~ 2365 tiles of 10 x 10 km
    ~ 53 GB / complete coverage

  Coordinate system: LV95 (EPSG 2056)

  Height system: The dataset is available in the Swiss height system LN02. However, for the regions located abroad, no altimetric transformation has been carried out from the original altimetric system to LN02.

  Precision: 1.5m (1 Sigma) These indications refer to the territory of Switzerland and the Principality of Liechtenstein and the regions close to their borders, as precisely measured reference points are available there.

  Geographical extent: swissALTI^Regio coverage extends at least 100 km beyond the Swiss border.
