High-Resolution Digital Elevation Model (HRDEM) in the Canadian Arctic – New data available!

April 12, 2018

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.

National Hydro Network (NHN) - 227 new watersheds

December 6, 2017

Publication of 227 NHN datasets, including 151 new watersheds at the completeness level NHN_CL3 and 76 improved NHN watersheds. With the publication of these watersheds, Canada is now almost entirely covered by NHN_CL2 or NHN_CL3 data, allowing analysis of hydrological networks.

52 new NHN_CL3 watersheds in the Atlantic provinces have been added to complete the NHN_CL3 coverage for the following provinces: Prince Edward Island, Newfoundland and Labrador, and Nova Scotia.

With the addition of 10 new NHN_CL3 watersheds in the Northwest Territories (NT), all NT watersheds are now NHN_CL3.

Also, 89 new NHN_CL3 watersheds have been added to Nunavut (NU), so over 95% of the NU watersheds are now NHN_CL3.

Furthermore, 20 NHN_CL2 or NHN_CL3 watersheds were produced to correct discrepancies.

As part of our regular maintenance activity, several watersheds have been regenerated to redefine watershed limits.

For more information, please consult the document National Hydro Network (NHN) - Release Note.

 

High-Resolution Digital Elevation Model generated from LiDAR data – Corrections

October 17, 2017

The datasets of three projects have been corrected due to a vertical Datum error. The projects affected by this problem were 2016_COCHRANE and 2016_PETERBOROUGH in Ontario and NBDNR-2016 in New Brunswick. These datasets published on September 29, 2017 could have elevation errors of up to 50 cm.

You can download the corrected HRDEM data from the Open Government portal or directly from the FTP site:

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

September 29, 2017

This 3rd publication of the High Resolution Digital Elevation Model (HRDEM) product covers more than 50,000 km2 of new territory and includes areas in Alberta, New Brunswick, Ontario, Quebec and Saskatchewan.

Also, the datasets from previous publications have been improved. Indeed, the 2 metre resolution data was replaced by data at 1 metre resolution when the density of the source data was sufficient.

For more information, please consult the Product Specifications. You can download 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.
