National Hydro Network (NHN) - 245 new watersheds (WS)

October 15, 2020

Summary : Publication of 245 NHN datasets including: 74 NHN-CL3 watersheds.

With the publication of these new watersheds, nearly 20% of watersheds covering Canada has been improved, allowing better analysis of hydrological networks.

Details:

  • 4 watersheds have been updated, using orthophotos and imagery (05OD000, 05OH001, 05OH002 and 05OG000)
  • 10 Canada/USA bi-national watersheds were regenerated
  • 74 watersheds have been improved into NHN-CL3
  • 8 watersheds were produced to correct anomalies.

Furthermore, in maintenance effort, 149 watersheds were re-generated following watershed limits redefinitions.

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

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

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

September 30, 2020

Natural Resources Canada (NRCan) is pleased to announce a new publication of the High-Resolution Digital Elevation Model (HRDEM).This new publication brings the total area of LiDAR-derived HRDEM to 385 000 km², an increase of 50 000 km² since the last update in October 2019.

This new data is distributed across six provinces: Alberta, British Columbia, Manitoba, Ontario, Quebec and Prince Edward Island (see the map below). 51 of Canada's 100 largest cities are now covered by the HRDEM product. This new data also covers areas vulnerable to flooding, including the Ottawa River and Fort McMurray regions. The LiDAR acquisitions for these two regions were funded by the Emergency Management Strategy for Canada.

This new highly detailed 3D information (see the images below) 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.

Explore the data!

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.

Instructions for downloading the MNEHR product are now available.

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 with various partners is a key factor in the success of the Strategy, both to release existing data and to acquire new LiDAR data across the country. The HRDEM product is part of the CanElevation Series created in support of the National Elevation Data Strategy.

2015 Land Cover of Canada – Landsat-8, 30-metre resolution now available!

November 28, 2019

The Canada Centre for Remote Sensing (CCRS) at Natural Resources Canada produced this second high-resolution dataset of Canada’s 15 land cover classes from 13,704 Landsat-8 satellite images taken between 2014 and 2016 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, including the identification of land cover changes against the 2010 baseline dataset released in April 2019.

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.

Visit the Physiographic Regions Interactive Map to learn more.
