National Hydro Network (NHN) - 212 new watersheds (WS)

July 11, 2018

Summary : Publication of 212 NHN datasets including: 186 NHN-CL3 watersheds and 26 NHN-CL2 watersheds. With the publication of these new watersheds, nearly 15% of watersheds covering Canada has been improved, allowing better analysis of hydrological networks.

Details:

As part of the project “Lake Winnipeg Basin Initiative”  watershed 05OF000 has been updated using orthophotos and imageries. This is the first out of 5 watersheds that will be completed in the coming years.

113 watersheds in NHN-CL2, NHN-CL3 or NHN-CL4 were produced to correct anomalies.

Furthermore, in maintenance effort, 98 watersheds were regenerated following watershed limits redefinitions.

For more information, please refer to the National Hydro Network (NHN) -  Release Notes.

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

CanMatrix – Georeferenced, CanMatrix – Print Ready and CanTopo collections are now available under one folder!

June 27, 2018

To facilitate search of our archived topographic raster maps, the CanMatrix - Georeferenced, CanMatrix - Ready to Print and CanTopo collections have been grouped under the following directory: http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/topographic/.

Here you will find the 6 scales available: 25k, 50k, 125k, 250k, 500k and 1M. This new directory structure allows you to quickly find all the editions/versions/formats available for a specific NTS file. The HTML index has been modified and there is a Readme in the documentation directory ".doc" on the FTP site to explain the new file nomenclature.

Please update your links as soon as possible.

CanVec: Update is Now Available!

May 28, 2018

This CanVec release includes the following updates:

  • Update of toponyms (entity and attribute)
  • Correction of 4 discrepancies for datasets and metadata

For more information, please refer to the CanVec - Release Note (accessible version).

Access CanVec data as prepackaged files through the FTP site, or by defining a custom area for downloading through the Geospatial Data Extraction tool.

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.

Text version

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.

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.
