High Resolution Digital Elevation Model (HRDEM)
The High Resolution Digital Elevation Model (HRDEM) includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived data. South of the productive forest line, DTM and DSM datasets are generated from airborne LiDAR data. In the north, they are derived from satellite images.
LiDAR Point Clouds Product
This product contains point clouds from various airborne LiDAR acquisition projects conducted in Canada. These airborne LiDAR acquisition projects may have been conducted by NRCan or by various partners. The point cloud files are distributed using the compressed .LAZ / Cloud Optimized Point Cloud (COPC) format.
