520 |a"The Canadian Digital Elevation Data (CDED) consists of an ordered array of ground elevations at regularly spaced intervals. These CDED are based on National Topographic Data Base (NTDB) digital files at the scale of 1:50,000 and 1:250,000, according to the National Topographic System (NTS). … CDED have assumed a major role in digital mapping. They are used in geographic information systems (GIS) for land management applications. CDED play the same roles that contours and relief shading do on conventional paper maps, but are more powerful analytically. In addition to providing estimated values of elevation points, CDED can be used to determine orientation and the slope of each point when used in GIS applications. CDED can also be used for terrain modeling, for calculating the influence of the terrain on line-of-sight, for radar imaging, for simulating flooding, and similar applications"--Introduction, page 1.
