SwissBUILDINGS3D 2.0 – data setMay 30, 2023Since March 1, 2021, Switzerland has been pursuing the “Open Government Data (OGD)” strategy and, in line with this innovation, all official geodata and products are freely available and can be obtained online free of charge. As part of this reform, the swissBUILDINGS3D 2.0 vector data set was made freely available to the public on April 1st and can be downloaded online via the website of the Federal Office of Topography swisstopo .What's new about the swissBuildings.
Dataset The swissBUILDINGS3D 2.0 data set DB to Data represents all 3D objects; with detailed roof shapes, roof overhangs, facades and floor plans. The data set covers the entire area of Switzerland and the Principality of Liechtenstein. Switzerland is definitely one of the pioneers in this area: as one of the first countries, Switzerland has created a 3D building model that offers an overview of the entire country.What's special: the buildings are depicted with a high level of precision and have an accuracy of +/- 30cm to 50cm in all three dimensions.
The minimum dimensions of 8m x 3m apply to the recording of buildings in the settlement area. Smaller buildings are generally not recorded in the data set. Exceptions are made for individual isolated buildings away from the settlement area. These are then usually recorded in the data set with smaller base masses.What is the difference between the 2.0 data set and its predecessor 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.
