image-based Digital Surface Models (bDOM)
— Derived, comprehensive digital surface model with a grid width of 1 meter
— For the area of the Free and Hanseatic City of Hamburg (without the area of the hamburg Wadden Sea)
An image-based digital surface model (bDOM) describes the Earth’s surface and the objects on it, such as structural systems, as regularly distributed, georeferenced high points at the time of recording the aerial images of a photogrammetric image flight (here: Spring flight 2020). The image-based surface models derive from oriented digital aerial images (i.e. R. Dense-Image-Matching).
The image-based surface model is created as an intermediate in the production process of digital orthophotos in the quality level TrueDOP.
The data are available in the following system:
Location: ETRS89_UTM32 (reference system ETRS89, figure UTM; EPSG code: 25832, obsolete name: Status 310)
Height: DE_DHHN2016_NH (Normal heights of the German Main Height Network 2016; obsolete name: Altitude status 170).
