Canadian Digital Elevation Model, 1945-2011

Canadian Digital Elevation Model, 1945-2011 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). In these data, elevations can be either ground or reflective surface elevations. A CDEM mosaic can be obtained for a pre-defined or user-defined extent. The coverage and resolution of a mosaic varies according to latitude and to the extent of the requested area. Derived products such as slope, shaded relief and colour shaded relief maps can also be generated on demand by using the Geospatial-Data Extraction tool. Data can then be saved in many formats. The pre-packaged GeoTiff datasets are based on the National Topographic System of Canada (NTS) at the 1:250 000 scale; the NTS index file is available in the Resources section in many formats. 2019-10-03 Natural Resources Canada geoinfo@canada.ca Form DescriptorsCanadaEarth ScienceselevationreliefgeomaticsGeoBaseCDEMDEMCDEDEarth sciencesCartographyGeographyGeographic dataGeographic information systemsGeomaticsTopography Canadian Digital Elevation Model, Color Shaded ReliefWMS https://maps.geogratis.gc.ca/wms/elevation_en?service=WMS&version=1.3.0&request=GetCapabilities&layers=cdem.color-shaded-relief&legend_format=image/png&feature_info_type=text/html Canadian Digital Elevation Model, Color Shaded ReliefWMS https://cartes.geogratis.gc.ca/wms/elevation_fr?service=WMS&version=1.3.0&request=GetCapabilities&layers=cdem.color-shaded-relief&legend_format=image/png&feature_info_type=text/html Customized files and derived products in ASCII Grid format (Geospatial-Data Extraction tool)ASCII Grid https://maps.canada.ca/czs/index-en.html Customized files and derived products in ASCII Grid format (Geospatial-Data Extraction tool)ASCII Grid https://maps.canada.ca/czs/index-fr.html Download directory to pre-packaged GeoTIFF filesGeoTIF http://ftp.maps.canada.ca/pub/nrcan_rncan/elevation/cdem_mnec/ Canadian Digital Elevation Model - Product SpecificationsPDF http://ftp.maps.canada.ca/pub/nrcan_rncan/elevation/cdem_mnec/doc/MNEC_specs_produit.pdf Canadian Digital Elevation Model - Product SpecificationsPDF http://ftp.maps.canada.ca/pub/nrcan_rncan/elevation/cdem_mnec/doc/CDEM_product_specs.pdf CDEM product index (drag and drop the kmz file in Google Earth to localize your region of interest)KMZ http://ftp.maps.canada.ca/pub/nrcan_rncan/elevation/cdem_mnec/index/cdem_index_250k.kmz NTS Index (Use to identify the number of your area of interest)HTML https://ouvert.canada.ca/data/fr/dataset/055919c2-101e-4329-bfd7-1d0c333c0e62 NTS Index (Use to identify the number of your area of interest)HTML https://open.canada.ca/data/en/dataset/055919c2-101e-4329-bfd7-1d0c333c0e62 Customized files and derived products in GeoTIFF format (Geospatial-Data Extraction tool)GeoTIF https://maps.canada.ca/czs/index-fr.html Customized files and derived products in GeoTIFF format (Geospatial-Data Extraction tool)GeoTIF https://maps.canada.ca/czs/index-en.html Documentation on the use of the Elevation APIHTML https://www.nrcan.gc.ca/earth-sciences/geography/topographic-information/web-services/elevation-api/17328 Documentation on the use of the Elevation APIHTML https://www.rncan.gc.ca/sciences-terre/geographie/information-topographique/api/api-elevation/api-elevation/17329
