Found 10 records similar to High Resolution Digital Elevation Model (HRDEM) - CanElevation Series
The High Resolution Digital Elevation Model Mosaic provides a unique and continuous representation of the high resolution elevation data available across the country. The High Resolution Digital Elevation Model (HRDEM) product used is derived from airborne LiDAR data (mainly in the south) and satellite images in the north. The mosaic is available for both the Digital Terrain Model (DTM) and the Digital Surface Model (DSM) from web mapping services. It is part of the CanElevation Series created to support the National Elevation Data Strategy implemented by NRCan.
This Shaded Relief Image has a resolution of 300 meters and was derived from the /Yukon 90m Shaded Relief/ from Environment Yukon, the /Canada 3D/ elevation model from Natural Resources Canada, and the United States Geological Survey /1:250k DEM of Alaska/.
Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows the degree of relief in Canada. This map is a general purpose relief map of Canada with elevation levels delineated by a graduated color scale. The elevation ranges above and below sea level are shown.
This Shaded Relief Image has a resolution of 500 meters and was derived from the United States Geological Survey /30 Arc-second Digital Elevation Model/.
This is a legacy product that is no longer supported. It may not meet current government standards. The Canadian Digital Surface Model (CDSM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. The 0.75-second (~20 m) CDSM consists of a derived product from the original 1-second (30 m) Shuttle Radar Topographic Mission (SRTM) digital surface model (DSM).
Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada is a map that shows all of the areas surrounding the Arctic Ocean; special features are shaded relief and bathymetry, ice-edge data, and Canada's offshore boundaries.
The Ontario Digital Surface Model (DSM) (Lidar-Derived) Land Information Ontario dataset is a raster product that provides a representation of both surface and ground features derived from a classified lidar point cloud. A DSM is the highest reflective surface of features captured by the sensor. This surface is also referred to as the first reflective surface. The DSM may include: * treetops * rooftops and tops of towers * telephone poles * other natural or artificial features * ground surface if there is no vegetative ground cover The DSM data is available in 1 km by 1 km non-overlapping tiles grouped into packages for download.
The Ontario Radar DSM has the following features: * source data: 1 arc second spaceborne C-Band Interferometric Synthetic Aperture Radar (IFSAR) data * MNR Lambert Conformal Conic Projection * vertical datum in both EGM96 and CGVD28, separately * elevation value: floating * local Polynomial Interpolation from vector elevation points * spatial resolution: 30 meter * asurface elevation model This product offers significant advancements in elevation data in the province. Read the details about these advancements and other technical specifications, including data processing, major spatial characteristics of the Radar DSM, and the steps to generate the Northern Ontario Radar DSM. *[MNR]: Ministry of Natural Resources *[DSM]: Digital Surface Model
Contained within the National Parks, 1961 to 1994, Atlas of Canada series, is a map that shows Jasper National Park. This bilingual map shows the topography of the park in great detail: it has contour lines (with a 500 foot interval), and it names a large number of mountains, giving their elevations in feet. The drainage within the park is also shown in detail, as are the glaciers in and around the park. Shaded relief is used on the map.
This collection is a legacy product that is no longer supported. It may not meet current government standards. The Canadian Digital Elevation Model (CDEM) is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. The CDEM stems from the existing Canadian Digital Elevation Data (CDED).
