This elevation data has the following specifications: The Canadian Digital Elevation Data (CDED) consists of an ordered array of ground elevations at regularly spaced intervals. The source digital data for CDED is extracted from the hypsographic and hydrographic elements of the National Topographic Data Base (NTDB) at scales of 1:50 000 and 1:250 000 or various scaled positional data acquired from the provinces and territories.

The coverage for each CDED file corresponds to half an NTS (National Topographic System) map sheet. CDED, is comprised of a Western and an Eastern section, for each NTS map. Depending on the latitude of the CDED section, the grid spacing (based on geographic coordinates) vary in resolution from 0.75 to 3 arc seconds for the 1:50 000 NTS tiles, and from 3 to 12 arc seconds for the 1:250 000 NTS tiles respectively. A CDED file consists of elevation data relative to Mean Sea Level (MSL), based on the North American Datum 1983 (NAD83) horizontal reference datum.
