Height models
Elevation models are digital data sets that describe the shape of the earth's surface in 3D. Each pair of coordinates X and Y is assigned a height Z. For precise calculations, so-called breaklines are often also evaluated.
Various data sets and different formats are available for using the data
DTM 2m Grid
For the use of 3D data, the raw height information is often converted to regular grids. The advantage of regular grids is that, unlike individual points, they can be processed and evaluated relatively quickly by software products.
Relief map
A relief map is a topographical map that depicts the relief, the three-dimensional shape of the earth's surface, in a two-dimensional representation. The aim of this type of map design is to achieve a vivid, three-dimensional effect.
Contour lines
Contour lines, also known as contour curves, connect neighboring points of the same height on maps (usually whole meters or 10 meters). Equidistance is the difference in height to the neighboring contour line.
