Urban Area Mapping

Previous Image

Here a larger segment (800 x 800 m) of the city of Bonn. This visualization is brightness-coded, i.e. low areas have darker colors and high areas and objects are brighter.

Streets and blocks of buildings can be identified clearly. The large flat strip in the middleground are the tracks of a railroad station, the darker line at the rear of this area is an emerging subway track.

This image is a digital surface model (DSM). But it is obvious that this type of data is also well suited to generate digital 3D city models.
