Digital elevation model

Digital Elevation Model (DEM) is a digital description of information about the elevation of the Earth's surface without taking into account vegetation, buildings and other high-rise objects located on it.

DEM can be represented in raster format (elevation marks in nodes of a regular grid with the formation of an altitude matrix) or vector format (elevation marks in irregular triangular network (TIN) or a set of contour lines).

DEM can be used to calculate vertical angles and slope exposures, analyze visibility/invisibility, build 3D images, build cross-section profiles, generate thalweg and watershed network lines, automate analytical terrain shading by calculating relative slope illuminations, digital orthotransformation and other computing operations and grapho-analytical constructions.
In Goskartgeofond, the DEM is usually stored in vector format as a set of contours, which can be easily converted to raster format and back, and covers almost the entire territory of the Republic of Belarus.
