Primary data/laser scan data of the Lasercsanner measurement recording including classification — Free State of Saxony

In order to create terrain and surface models, the earth’s surface is detected by means of laser scanner measurement. As a result, there is an irregular point cloud (so-called primary data or laser scan data). The laser scan data are georeferenced and are distinguished by 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 data format LAZ. The additional points are also stored in the files.
