Service Description: The National Elevation Strategy, led by Natural Resources Canada, aims to increase high-resolution elevation data coverage for Canada and improve accessibility to the products.In the southern part of the country, Digital Elevation Models (DEMs) and derived data (e.g. shaded relief, slope, etc.) are generated from airborne LiDAR data. They are offered at a 1 m or 2 m resolution. The datasets at a 1 m resolution cover an area of 10 km x 10 km while datasets at a 2 m resolution cover an area of 20 km by 20 km. In the northern part of the country, DEMs are derived from autocorrelation of high resolution optical satellite images. They cover an area of 50 km by 50 km at a 2 m resolution. This web service represents the current state of the available zones and is updated as new areas become available.
