High-Resolution Digital Elevation Model (HRDEM): The Canadian Arctic like you've never seen it before !

August 29, 2019

Natural Resources Canada (NRCan) is proud to announce a new release of the High Resolution Digital Elevation Model (HRDEM) product for the entire Canadian Arctic! This new data at 2m replaces the previous 5m resolution version and completes the new offer of high-resolution elevation data for the Northern part of the National Elevation Data Strategy. This milestone is significant for the Government of Canada as the data offers to view the Canadian Arctic in 3D like we've never seen it before! The data comes from the ArcticDEM project, which aimed to provide high-resolution digital surface models for all the Arctic regions of the planet. NRCan applied corrections and improvements to the data according to the Canadian standards. This highly detailed 3D information will be very useful for planning operations in the North without costly or risky on-site missions. Moreover, it will help scientists to remotely monitor changes related to coastal erosion, melting glaciers, deforestation, road construction and more.

For more information on this new data and on the improvements that were performed, 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.

About the National Elevation Data Strategy

The National Elevation Data Strategy aims to increase 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 thus acquired by multiple projects from different partners. The HRDEM product is part of the CanElevation Series created in support of the National Elevation Data Strategy.

2010 Land Cover of Canada – Landsat-7, 30-metre resolution now available!

April 11, 2019

The Canada Centre for Remote Sensing (CCRS) at Natural Resources Canada produced this new high-resolution dataset of Canada’s 15 land cover classes from 13,350 Landsat-7 satellite images taken between 2009 and 2011 for cloud- and snow-free national coverage. The 30-metre resolution of the dataset will help improve the accuracy of local and regional-scale analyses and applications.

About 2010 Land Cover of Canada

CCRS produced 2010 Land Cover of Canada as part of the Commission for Environmental Cooperation (CEC) North American Land Change Monitoring System (NALCMS) in partnership with the United States and Mexico. The continental and national datasets will provide baseline for refreshed 30-metre resolution land cover of Canada and North America every five years.

Physiographic Regions of Canada

April 1, 2019

Physiographic Regions of Canada are now available as an interactive map.

Canada’s landmass is very diversified and comprises several distinctive areas, called physiographic regions, each of which has its own topography and geology. Physiographic regions are large areas that share similar relief and landforms shaped by common geomorphic processes and geological history. Physiographic regions are often used to describe Canada’s geography to show regional differences in climate, vegetation, population and the economy.

This map shows the location of seven physiographic regions, twenty-one sub-regions and their divisions with accompanying descriptive images and text.

National Hydro Network (NHN) - 122 new watersheds (WS)

March 19, 2019

Summary: publication of 122 NHN datasets including 31 NHN-CL3 or NHN-CL2 completeness level watersheds.

With the publication of these new watersheds, nearly 10% of watersheds covering Canada has been improved allowing better analysis of hydrological networks. In addition, all territories are now at completeness level NHN-NC3.

Details:

  • One watershed, "05OE000" has been updated using orthophotos and imagery as part of the project « Lake Winnipeg Basin Initiative »
  • One Canada/USA bi-national watersheds were regenerated as part of NHN maintenance work
  • 31 watersheds have been improved into NHN-CL2 or NHN-CL3
  • 26 watersheds were produced to correct anomalies
  • 63 watersheds were regenerated following watershed limits redefinitions.

Maintening NHN is done as part of the GeoBase Surface Water Program (GeEAU).

For more information about the Hydrographic Network Quality, please refer to the Completeness Level.

Please note that the GML format is no longer available.

Automatically Extracted Buildings are now available on OpenMaps!

February 26, 2019

Natural Resources Canada is pleased to announce its new data layer on OpenMaps. The richness of this new data layer comes from information on height and elevation of the buildings that will help support Canadian governments priorities such as emergency management, particularly for flood and earthquake risk analysis. This release contains close to 1 million building footprints. We will expand this coverage as more LiDAR data becomes available over Canada.
