Normalized DOM 0.25-meter grid (photogrammetric)
Description
The normalized digital surface model (nDOM) is a derived product from the difference between the photogrammetric digital surface model (DOM) of 23.06.2016 (resolution 0.25m) and the digital terrain model (DTM) of the LiDAR aerial flight of 05.04.2014, which contain high-precision elevation data to the Earth's surface (point grid with resolution 0.5m). While the DTM data was collected using the Airborne Laser Scanning (LiDAR) method, the DOM data comes from photogrammetry.
