Natural Resources Canada (NRCan) is proud to announce a new release of the High Resolution Digital Elevation Model (HRDEM) product for the Canadian Arctic! This new data covers nearly 3 million km² north of the 60th parallel. The data comes from the ArcticDEM project which aims to provide high-resolution digital surface models for all the Arctic regions of the planet. NRCan applied corrections and improvements to the data when possible.
This image represents the National Elevation Data Strategy Status in Canada as of April 2018. The image consists of a map of Canada with the coverage of the HRDEM (High-Resolution Digital Elevation Model) files. The North of the 60th parallel the HRDEM area is in blue (80% of the territory) and the south of the 60th parallel the regions covered by HRDEM files are in green (4% of the territory), mostly concentrated in Manitoba, Ontario, Quebec, New Brunswick and Nova Scotia. The Canada Centre for Mapping and Earth Observation has created this map.
Explore the data!
You can download the HRDEM data from the Open Government Portal. Use one of the following options to view the current inventory and to download datasets: "View on Map", "Project Footprints" or "Dataset Footprints", in KML, Shapefile or ESRI REST formats.
The level of details of this new data represents a significant advance if compare to the previous elevation products and, at the same time, offers great potential for the study of northern Canada.
For more information on this new data and the improvements that were performed, please consult the Product Specifications.

About the National Elevation Data Strategy
The National Elevation Data Strategy, implemented by NRCan, aims to increase Canada high-resolution elevation data coverage for Canada and improve accessibility to the products. Collaboration is a key factor to the success of the Strategy. Data is acquire by multiple projects from different partners. The HRDEM product is part of the CanElevation Series created in support of the National Elevation Data Strategy.
