The 1.0?In contrast to its predecessor model, the swissBUILDINGS3D 1.0, which was still presented as a block model, the renewed swissBUILDINGS3D 2.0 model is much more differentiated. It no longer just shows the individual buildings as generalized floor plans, but rather based on 3D measurements. The almost precise accuracy within the 3 different dimensions, the extensive coverage of the catchment area and the almost accurate, realistic representation of the buildings make this new model an extremely.
Important and high-quality basic data set for DB to Data various applications.The swissBUILDINGS3D 2.0 vector data is subject to a tracking cycle of 6 years and is therefore completely updated every 6 years. The data is recorded fully automatically (floor plan and facade); only the shape of the roofs is added manually.How are 3D vector data created?The data set is based on the current digital aerial photography strips from swisstopo. The aerial images are taken by satellites or aircraft and are a snapshot of the underlying landscape.
Serve as the basis for further geometric processing into a 3D model. There is a distinction between orthophotos and 3D aerial photographs.Orthophotos are true-to-scale and distortion-free images of the landscape that can be used for precise coordinate, area and distance calculations. They have a high resolution and are generally very up-to-date.3D aerial photography strips, on the other hand, usually depict individual sub-areas, with the landscape being recorded in strips from different perspectives.
