Canada Base Map Elevation (CBME) consists of a simple light hillshade for use as a background for mapping application. The Canada Atlas Lambert (EPSG:3978) is used and only covers the extents of Canada.

The dataset shows global bathymetry based on The General Bathymetric Chart of the Oceans (GEBCO) 2019. The dataset represents a continuous model of seafloor topography derived from a combination of multibeam, singlebeam and satellite altimetry data. The original global grid has been reprojected to UTM zone 24N to support regional use and integration with other geological and geophysical datasets covering Greenland and the North Atlantic.

The dataset is based on OpenStreetMap (OSM) data downloaded from the official OpenStreetMap distribution platform. The data have subsequently been processed and published as a customised web service. OpenStreetMap is an open, crowdsourced geospatial dataset that is continuously maintained and updated by a global community of contributors. The dataset contains vector-based geographic features, including transport networks, buildings, land use, hydrography, natural features, and points of interest. The data are used as a background map and reference dataset for map visualisation and spatial analysis at local, regional, and national scales. Data content and quality vary geographically and depend on contributor activity.

Canada Center for Mapping and Earth Observation (CCMEO)'s basemap is essential in supporting the Government of Canada’s priorities in areas such as open government, climate change mitigation, Indigenous reconciliation, emergency management, disaster preparedness and response, sustainable natural resource management, infrastructure planning, economy/labour and more. It reinforces CCMEO’s commitment to improving the accessibility, interoperability and integration of geospatial data across Canada. CCMEO currently offers multiple basemap types which include the following found in this series: - Transportation basemap (CBMT) in raster tile format - Transportation basemap (CBMT) in vector tile format EPSG: 3857 (WGS84 Pseudo-Mercator) - Transportation basemap (CBMT) in vector tile format EPSG: 3978 (NAD83 Canada Atlas Lambert) - Digital Elevation Model (DEM) - hillshade basemap (CBME) - Simple grey basemap - Provinces/Territories basemap - Grids (Lat/Long, NTS and UTM) basemap

The topographic map of Greenland at a scale of 1:250.000 is based on data collected from the 1930s through the 1970s and 1980s. These data formed the basis for the production of a series of 1:250.000 scale topographic map sheets, which continue to serve as the primary topographic reference for large parts of Greenland. Mapping of areas prior to 1970 was based on several historical map series, including 18 map sheets at a scale of 1:300.000 covering North Greenland produced by Lauge Koch between 1932 and 1940, 1:250,000 scale mapping of parts of Northeast Greenland conducted by the Geodetic Institute in the 1930s, and complete national coverage at 1:250.000 produced by the American Army Map Service in the 1950s. The digital topographic map of North and Northeast Greenland has been produced by the Geological Survey of Denmark and Greenland (GEUS) since 1977, based on high-precision digital photogrammetry using aerial photographs. The dataset has primarily been used as a topographic reference for geological mapping at scales of 1:100.000 and 1:500.000.
