ATKIS — DGM1 (2016)

DGM1 — Laserscan terrain model In spring 2016, an airborne laser scan flight was held to generate a new high-precision terrain model for the entire Saarland. The terrain surface was scanned with a laser installed in the aircraft. As a result, the high-precision DGM1 with a grid width of 1 m and an average height accuracy of 1-2 dm has been available since the beginning of 2017. As a desired side effect, in addition to terrain data, objects such as buildings and vegetation on the Earth’s surface were scanned, which are available as surface data. Digital terrain models (DGM) are digital, numerical, reduced to a regular grid models of terrain heights and shapes of the earth’s surface. DGM may also contain additional information (e.g. terrain edges, rib lines, distinctive terrain points). They do not contain information about buildings (e.g. bridges) and vegetation. The DGM1 differs from the other DGM due to its height accuracy and grid width.
