Altitude information from the laser scanning flight of the city of Braunschweig 2019
Description
In February 2019, a laser scan flight took place across the city of Braunschweig in cooperation with the State Office for Geoinformation and State Surveying of Lower Saxony (LGLN) and the city drainage Braunschweig GmbH. As a result, classified elevation points of the surface with a point density of more than 8 points/m² are available. The altitude accuracy of the measurement data/single point coordinates is ± 0.15 m (standard deviation). It is usually much better, as shown by terrestrial comparative measurements in the urban area. The original raw measurement data are available as a 3D point cloud (irregularly distributed single points) in the format LAS/LAZ. A delivery in further data formats as well as as thinned point data sets, interpolated to regular dot grids is possible. On request, individually pronounced elevation representations, such as elevation lines, digital terrain models (DGM) and digital surface models (DOM) can be derived and offered as a data set or map thereof.
