Since data is being acquired by project, there is no integration or edgematching done between projects. Source data for HRDEM datasets is acquired through multiple projects with different partners. The HRDEM product is referenced to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the reference standard for heights across Canada. In this case, these products will be generated with the same specifications as those generated from airborne LiDAR in the southern part of the country. For some locations in the north, DSM and DTM datasets can also be generated from airborne LiDAR data. Each dataset covers an area of 50 km by 50 km.

They are generated at a 2 m resolution using the Polar Stereographic North coordinate system referenced to WGS84 horizontal datum or UTM NAD83 (CSRS) coordinate system. Most of these datasets have optical digital images as their source data. In the northern part of the country (north of the productive forest line), due to the low density of vegetation and infrastructure, only DSM datasets are generally generated. The datasets at a 1 m resolution cover an area of 10 km x 10 km while datasets at a 2 m resolution cover an area of 20 km by 20 km. They are offered at a 1 m or 2 m resolution and projected to the UTM NAD83 (CSRS) coordinate system and the corresponding zones.

In the southern part of the country (south of the productive forest line), DTM and DSM datasets are generated from airborne LiDAR data. This line is approximate and may change based on requirements. The productive forest line is used to separate the northern and the southern parts of the country.

For DTM datasets, derived data available are slope, aspect, shaded relief, color relief and color shaded relief maps and for DSM datasets, derived data available are shaded relief, color relief and color shaded relief maps. It includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived data. The complete coverage of the Canadian territory is gradually being established. High Resolution Digital Elevation Model (HRDEM) - CanElevation Series The High Resolution Digital Elevation Model (HRDEM) product is derived from airborne LiDAR data (mainly in the south) and satellite images in the north.
