3DHöhenmappe
3DHöhenmappe is a term used in German-speaking geospatial contexts to denote a digital representation of a terrain surface as a height field, stored on a regular grid. Each cell contains an elevation value, typically relative to a geoid or ellipsoid, forming a 3D surface when interpolated. It is commonly referred to as a Digital Elevation Model (DEM) or heightmap in English.
Applications of 3DHöhenmappe include terrain visualization, hydrological modeling, 3D city modeling, line-of-sight analyses, and as input
Formats commonly used for 3D heightmaps include GeoTIFF, ESRI ASCII Grid, ASCII XYZ, IMG, and other raster
Generation and processing involve measuring ground elevations and encoding them into a grid. After acquisition, steps
Limitations of heightmaps include representing bare-earth elevation and often excluding vegetation and built structures unless a
