Ontario Digital Surface Model (Imagery-Derived)

The Ontario Digital Surface Model (Imagery-Derived) is a raster elevation product that was generated from the elevation point clouds created via pixel-correlation from aerial photography.

A DSM is the highest reflective surface of features captured by the sensor. This surface is also referred to as the first reflective surface. The DSM may include:

  • treetops
  • rooftops and tops of towers
  • telephone poles
  • other natural or artificial features
  • ground surface if there is no vegetative ground cover

This data is for geospatial tech specialists, and is used by government, municipalities, conservation authorities and the private sector for land use planning and environmental analysis.
