Digital surface models describe the actual landscape at the time of the flight with all fixed and movable objects that do not belong to the terrain surface. These are mainly forests and buildings (houses, bridges and high-voltage lines) as well as the resting and flowing traffic. A regular grid was automatically derived from the irregularly distributed first pulse data of the laser scan recording and can therefore contain implausible values. A special accuracy assessment is therefore not possible. It is available nationwide and can be dispensed in grid widths from 5 m.
