Providing applied geoinformation requires appropriate methods and processes for photogrammetric mapping. In addition to urban 3D-reconstruction from point clouds the department is concerned with automated derivation of semantic information. Derived geometry is used to generate linking properties while spectral image information serves as basis for extracting further attributes. In this way the detection of windows on a building facade leads to the number of storeys or object-based classification to separated parts of a building complex.
As a consequence from research on automatable algorithms some processing procedures gain real‑time capabilities. Exemplarily this means aerial images can be projected with full resolution into a map while the acquisition process is still ongoing. Thereby coordinates and evaluable image data are instantly available for particular purposes. Relevant applications are to be noted in the field of coastal management and civil protection such as large‑scale dike monitoring, precise localization of forest fires as well as maritime salvage.
