Listed in Ontario Open Government Data
The Ontario Digital Surface Model (DSM) (Lidar-Derived) Land Information Ontario dataset is a raster product that provides a representation of both surface and ground features derived from a classified lidar point cloud.
Description
A DSM is the highest reflective surface of features captured by the sensor. This surface is also referred to as the first reflective surface.

- treetops
- rooftops and tops of towers
- telephone poles
- other natural or artificial features
- ground surface if there is no vegetative ground cover The DSM data is available in 1 km by 1 km non-overlapping tiles grouped into packages for download. This dataset is a compilation of lidar data from multiple acquisition projects, so specifications, parameters and sensors may vary by project. 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.
