Digital terrain model

De termen DEM, DTM en DSM worden echter veelvuldig verward of anders gedefinieerd. A digital elevation model (DEM) is a digital model or 3D representation of a terrain’s surface — commonly for a planet (including Earth), moon, or asteroid . In practice, these terms (DTM, DEM, DHM, and DTEM) are often assumed to be synonymous and indeed this is often the case.

Nederland is vlak maar kent toch subtiele hoogteverschillen. Deze verschillen zijn belangrijk voor Telecommunicatiebedrijven, . A digital terrain model (DTM) is different than a digital elevation model (DEM), the first representating a continuous surface as if all the objects . The DTM utility (command) for AutoCAD automatically creates an irregular triangular network (3DFACEs, 3DMESH) from a given selection set of 3D objects.

Digital terrain models are representations of land surface point elevations. They are used as input for the generation of surface models and . Veel vertaalde voorbeeldzinnen bevatten digital terrain model – Engels-Nederlands woordenboek en zoekmachine voor een miljard Engelse vertalingen.
