Dataset description

The data of the Digital Terrain Model 1 (DGM1) with 1 m grid are derived from laser scan data and photogrammetric evaluations (image correlation). The position accuracy of the laser scanning process is <=30 cm. The height accuracy corresponds to ± 0.2 m. The DGM1 currently serves as “output DGM” for the derivation of digital terrain models 5, 10, 25 and 50 (DGM5, DGM25, DGM50). The Digital Terrain Model 1 was obtained using the aircraft-assisted laser scanning process. Here, 3 to 4 measuring points were generated per square metre. The coordinate dimension of DGM data is 3D.
