The HRDEM and HRDEM Mosaic products are part of the CanElevation Series created in support of the National Elevation Data Strategy. The Ontario Lidar Digital Terrain Model (DTM) Land Information Ontario (LIO) Dataset is a raster product representing the bare-earth terrain derived from a classified lidar point cloud. 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 National Elevation Data Strategy aims to increase high-resolution elevation data coverage for Canada and improve accessibility to the products. About the National Elevation Data Strategy The WMS service facilitates the visualization of the mosaic and its derived products, while the WCS provides access to the source data. The HRDEM Mosaic is also available from WMS and WCS web mapping services – see the product specifications for more details.

A download procedure for the HRDEM product is also now available. For more information on the HRDEM product, consult the product specifications. Use one of the following options to view the current inventory: "View on Map", "Project Footprints" or "Dataset Footprints". The HRDEM data can be downloaded from the Open Government Portal in KML, Shapefile or ESRI REST formats. This highly detailed 3D information provides essential foundational geospatial data for many government projects and priorities, such as flood mapping, forest inventories, climate change monitoring and urban management. The 10,000 km2 project was carried out in collaboration with the City of Ottawa, the City of Gatineau, NRCan, the National Capital Commission (NCC) and the Province of Ontario and supported by the Emergency Management Strategy for Canada.

This includes the entire area of both the National Capital Region and the Ottawa River, areas that are highly vulnerable to flooding. With the addition of this data, 61 of Canada's 100 largest cities are covered by the HRDEM product and the HRDEM Mosaic. The data is distributed across eight provinces: British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland and Labrador (see map below). The total area of high-resolution elevation data derived from LiDAR is now nearly 500,000 km². DTMs support contours, orthorectification.

This data is consumable in CAD and GIS compatible software programs.Natural Resources Canada (NRCan) is pleased to announce the release of over 100,000 km2 of new data in the High-Resolution Digital Elevation Model (HRDEM) and HRDEM Mosaic. Sanborn Digital Elevation Models (DEM) support 3D modeling, volumetric calculations, and powerline surveys.

A Digital Terrain Model (DTM) is a DEM in which terrain data has been further enhanced with breaklines, creating greater accuracy as. DEMs are generated from variably-spaced Lidar ground points, or they can be created using a raster grid. The Terrain - 20K Digital Elevation Models data includes a GIS-ready mapping database created by Alberta Environment and Parks and includes the following: three dimensional spatial ground elevation masspoints, hard breaklines, and soft breaklines. A digital elevation model is a 3D representation of the terrain elevations found on the earth’s surface. (SDW), on behalf of the Government of Alberta. (ADP), formerly Spatial Data Warehouse Ltd.
