Our specialists derive further products from the swisstopo geodata. This enables us to cover both frequently requested and very specific customer needs.

In February, swisstopo conducted a survey on 3D geodata. Many thanks to all participants. Even though the detailed evaluation and conclusions are still pending, the first results are already available and can be viewed under the following link: survey results 3D packages

The extent to which the results will be incorporated into new products and services is still open and will be analysed once the evaluation has been completed.

A few examples are presented below:

Calculation of terrain contours

Example of a contour data set calculated from a terrain model

 

Terrain contours are derived directly from a digital height model, generally swissALTI3D.

Technical aspects:

  • Minimal equidistance 1 metre
  • Delivery formats: Shapefile or DXF/DWG

Terrain FBX

Representation of the terrain in FBX-format

The terrain model in FBX format is represented as a 3D mesh, analogous to the GeoAdmin Terrain Service. The FBX format is well suited for use in various 3D modelling, augmented or virtual reality (AR/VR) development environments.

Technical aspects:

  • The terrain is offered in regular tiles.
  • The tile size is 1/16 of a 1:25'000 national map sheet (approx. 13km2).
  • You can choose between different resolution levels, min. 0.5- max. 128.
  • Each resolution level corresponds to the tolerance in metres permitted in the generalization process.
  • Significant terrain forms such as crests, peaks and large differences in altitude are retained at each resolution level.

Buildings OBJ

Buildings from swissBUILDINGS3D 2.0 in OBJ-format

 

By offering the buildings of swissBUILDINGS3D 2.0 in OBJ format, the integration of the 3D data set into AR/VR development environments and applications is facilitated.

Technical aspects:

  • The buildings are grouped in regular tiles (tile size is 1/16 of a 1:25'000 national map sheet (approx. 13km2))
  • Each building is saved as a separate OBJ file. If required, these can be combined per tile.
  • The buildings can be controlled as independent objects.
  • Each building consists of a roof and building envelope. These two elements can be addressed as separate groups.
  • The attributes including the building position are saved per tile in a JSON file.
  • Further product specifications can be found on the swissBUILDINGS3D 2.0 product page

The sample data show their type and format. They are free of charge and can be used for test purposes.
