3D-City Models

Felicitas Lang, Uwe Weidner

Task

There is an increasing need for 3D-descriptions of urban areas for various applications such as town planning, microclimate investigation or transmitter placement in telecommunication. This information is literally unavailable. City plans contain 2D-information about the ground plan of buildings, possibly encoded with some height relevant information such as the number of stories.

At our institute, we developed a system for semiautomatic building extraction using digital aerial images as input, and a system which aims at automatic extraction of buildings using highresolution Digital Surface Models (DSM) as input.

• General overview
• General framework
• Semiautomatic building extraction using digital images (see also here for newer developments)
• 3D-City-Movie (MPEG, 160K, color map problems with Netscape)
• Building Extraction by DSM-Analysis
• 3D-Building Reconstruction using Multiple Images
