The award winning 3D City Database is a free 3D geo database to store, represent, and manage virtual 3D city models on top of a standard spatial relational database. The database model contains semantically rich, hierarchically structured, multi-scale urban objects facilitating complex GIS modeling and analysis tasks, far beyond visualization.

The 3D City Database comes with additional software providing easy data exchange or facilitating coupling with cloud services. The 3D City Database content can be directly exported in KML and COLLADA formats for the visualisation in a broad range of applications like Google Earth, ArcGIS and ArcGIS Explorer.
