Digital elevation model Hamburg DGM 10

Description

Derived, comprehensive digital terrain model with a grid width of 10 meters based on the DGM1. For the area of the Free and Hanseatic City of Hamburg (excluding the area of the Hamburg Wadden Sea), a laser scan (airborne laser scanning) was carried out in 2020. The data are available in position status 310 (ETRS89/UTM), with elevation data above normal altitude zero (NHN), according to DE_DHHN2016_NH. The accuracy of a single measuring point in clearly defined areas, such as on road surfaces, is approx. ± 105 cm. In areas of shading (bridges), vegetation, especially areas in forest and shrub areas and on steeply inclined terrain, the accuracy is lower. By default, the LGV offers the following grid widths: DGM 1 (grid width 1m), DGM 10 (grid width 10m), DGM 25 (grid width 25m). An annual update of this data is carried out by aerial surveys. In addition to the pure provision of height information as a regular grid, the data is also provided as a service in a triangular mesh (TIN). Data exchange with 2D and 3D CAD systems is ensured. As a further service, contour lines and profiles can be derived, for example, or volumes and inclinations can be calculated. By integrating further geobase and technical data (vector and grid data), further services can be derived, e.g. for the areas of water management, civil engineering, environment and urban planning as well as energy supply for large and small-scale applications.
