New High-Resolution Digital Elevation Model / LiDAR

Now available: the High Resolution Digital Elevation Model (HRDEM), at a resolution of 2 metres. The HRDEM consists of a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and others derived data.   This first release covers 106,000 km2 (3%) of the 3.5 million km2 planned for the Canadian southern territory, and includes areas in New Brunswick, Nova Scotia, Quebec, and Manitoba.

This new product is generated from airborne LiDAR data acquired in partnership with provinces and territories to provide high accuracy data with minimum distortion.  The HRDEM is part of the CanElevation collection created in support of the National Elevation Strategy implemented by Natural Resources Canada.  This strategy aims to increase Canada’s coverage of high-resolution elevation data and increase product accessibility.
