Canadian Digital Elevation Model 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. The pre-packaged GeoTif 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 Data Resources section(Shape, KML). 2015-01-01 2018-05-31 Natural Resources Canada Geoinfo@Canada.ca Form DescriptorsCanadaEarth ScienceselevationreliefgeomaticsGeoBaseCDEMDEMEarth sciencesCartographyGeographyGeographic dataGeographic information systemsGeomaticsTopography Canadian Digital Elevation Model, Color Shaded Relief (Couche)WMS 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 Modèle numérique d`élévation du Canada, Relief ombré coloré (Couche)WMS 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 (derived products, selectable extent) - Geospatial-Data Extraction tool (English)HTML http://maps.canada.ca/czs/index-en.html Customized files (derived products, selectable extent) - Geospatial-Data Extraction tool (French)HTML http://maps.canada.ca/czs/index-fr.html Pre-packaged GeoTIF files (download directory)GeoTIF http://ftp.geogratis.gc.ca/pub/nrcan_rncan/elevation/cdem_mnec/ Canadian Digital Elevation Model - Product Specifications (French)PDF http://ftp.geogratis.gc.ca/pub/nrcan_rncan/elevation/cdem_mnec/doc/MNEC_specs_produit.pdf Canadian Digital Elevation Model - Product Specifications (English)PDF http://ftp.geogratis.gc.ca/pub/nrcan_rncan/elevation/cdem_mnec/doc/CDEM_product_specs.pdf CDEM product index (drag and drop the kml file in Google Earth to localize your region of interest)KML http://ftp.geogratis.gc.ca/pub/nrcan_rncan/elevation/cdem_mnec/index/cdem_index_250k.kml NTS IndexSHP http://ftp.geogratis.gc.ca/pub/nrcan_rncan/vector/index/nts_snrc.zip
