This digital semantic 3D city model was generated entirely from open data within a study project conducted by the Chair of Geoinformatics of the Technical University of Munich.
The solar irradiation tool, developled by the Chair of Geoinformatics, estimates the direct, diffuse and global irradiation in different spatial and temporal resolutions. The video displays the results for a global irradiation calculation in kWh per year for buildings as well as streets in the form of textured surfaces visualized using the 3DCityDB Web Map Client.
