swissSURFACE3D Raster (DSM)

Note

This dataset is currently only available to those in the insiders program

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. swissSURFACE3D Raster is derived from airborne LiDAR data of swissSURFACE3D. To model the surface, the following elements (classified LiDAR points) are used:

  • soil (class 2)
  • vegetation (class 3)
  • buildings (class 6)
  • bridges / footbridges / viaducts (class 17)
  • water (class 9)

To improve the surface representation of large rivers and lakes, watercourse vectors of the topographic landscape model TLM are implemented.

Data preprocessing

Datasets were preprocessed and distributed in multiple formats. The Cloud Optimized Geotiff files were made available and a program was written to go fetch all and current 31,321 tiles.
