High-Resolution Digital Elevation Model (HRDEM) generated from LiDAR – New data available!

November 25, 2019

Natural Resources Canada is pleased to announce a new publication of High-Resolution Digital Elevation Model (HRDEM). This 100 000 km² release includes ~55,000 km² of new HRDEM coverage distributed over five provinces (SK, MB, ON, QC and NB). It also includes coverage of 22 of Canada's largest cities, including those in the Greater Toronto Area. With this publication, high-resolution elevation data now covers 44 of Canada's 100 largest cities!

This new highly detailed 3D information is an essential baseline for many government projects and priorities, such as flood mapping, forest inventories, climate change monitoring and urban management (e.g. smart cities).

For more information on the HRDEM product, consult the Product Specifications.
