Primary data / Laser scan data of the Lasercsanner measurement recording including classification - Free State of Saxony

Description

In order to create terrain and surface models, the earth's surface is recorded by means of a laser scanner measurement image. The result is an irregular point cloud (so-called primary data or laser scan data). The laser scan data is georeferenced and differentiated according to first-echo points, load-echo points and only-echo points. The laser scan data is classified into ground points and non-ground points. Gaps are filled by interpolated points (so-called supplementary points). The laser scan data is stored in the LAZ data format. The additional points are also stored in the files. The update has been carried out in batches every 6 years since 2020/2021 (2 lots per year).
