Image-based Digital Surface Models (bDOM)
abgeleitetes, flächendeckendes digitales Oberflächenmodell mit einer Rasterweite von 1 Meter
für die Fläche der Freien und Hansestadt Hamburg (ohne das Gebiet des hamburgischen Wattenmeeres)
An image-based digital surface model (bDOM) describes the earth's surface and the objects on it, such as structures, as regularly distributed, georeferenced elevation points at the time of taking the aerial images of a photogrammetric image flight. The image-based surface models are derived by image correlation (usually dense image matching) from oriented digital aerial images.
The image-based surface model is created as an intermediate product in the production process of digital orthophotos in the TrueDOP quality level.
The data are available in the following system:
Location: ETRS89_UTM32 (reference system ETRS89, figure UTM; EPSG code: 25832, obsolete name: Situational status 310)
Height: DE_DHHN2016_NH (Normal heights of the German main elevation network 2016; Outdated name: elevation status 170).
