Canada gets complete digital elevation dataset

Canada: Acquisition of the Canadian Digital Elevation Data (CDED), as part of GeoBase initiative, is now complete. 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 the Geospatial Data Base (GDB), or various scaled positional data acquired by the provinces and territories, or remotely sensed imagery.

CDED plays the same role as contours and relief shading on conventional paper maps. CDED serves as a key primary data in a range of applications critical to achieving sustainable development.
