Our world is increasingly described three-dimensionally. 3D computer models play an important role in city planning, tourism, and knowledge transfer. The CityServer3D allows for the first time to make a lively use of 3D city models. The software can manage two- and three-dimensional geographic data and connect them to each other. The CityServer3D automatically generates three-dimensional models and so also carries out simulations in the 3D world.
The technology of the CityServer3D consists of a geo-database, a server with numerous interfaces for the import and export of the data and applications for the development of landscape models. An administration software allows to process the data and the web viewer takes them by Internet onto the user's screen.
