Geodata for the Bernese 3D Web GIS

In February, our employees successfully completed the project concerning an update of the Bernese landscape model.

The Bernese geoinformation departement is developing a 3D web GIS based on high-resolution aerial geodata combined with data from the official survey. The Web GIS is expected to go online in the first half of 2021. For the update of the existing landscape model, recent laser data and aerial images were needed. These data were acquired by BSF Swissphoto in a combined aerial survey in summer 2020, showing a point density of 25 points/m2 and a resolution of 5 cm, respectively. BSF Swissphoto finally delivered the colored and detailed classified point cloud as well as special elevation models with leveled buildings and waters.

With the 3D Web GIS, the city of Bern aims to fulfill many needs. One goal is to build a 3D tree cadastre. Also the improvement of the 3D city model as well as the offer of a database for different departments are important tasks.
