derivation and editing of 3D-building Models on basis of arbitrary point clouds
(Laserscanning and Matching) which are consistent to the building ground plan.
The usage of standardized roofs helps to generalize the roofs and to realize a
3D-building Model continuously in a reasonable time. The percentage of post-
editing is between approximately 15 and 50 % and is depending on the building
density, the difficulty of the area to be edited and the quality of the laser point
cloud.
Due to the ground resolution of the aerial photographs of about 0.2 m, point
clouds from Matching can be created in a resolution of up to 25 points per square
meter. Because of the big amount of data for the practical use, a reduction of the
point density to 4 points per square meter is sufficient. Ultimately, a significant
quality improvement of the cadaster can be achieved by the creation of a statewide
3D-building Model with additional inspection and editing of the existing data.
