DSMs: digital surface models represent the reflective surface of the earth (bare earth plus trees, buildings).DEMs: digital elevation models represent the land or 'bare earth' (no trees, buildings, etc.).It is possible to create DEMs from contours and contours from DEMs using GIS software. 900m 2 in a DEM with a 30m resolution) that the pixel covers.

DEMs are raster datasets that have pixels like a digital image, except that each pixel contains an elevation value for the land area (e.g. Contour lines are the elevation lines you often see on topographic maps and they are generally measured in feet or metres above sea level.
