3D Models of Cities from Satellite
Images are Useful for Estimating the Properties of Buildings

For estimating losses due to earthquakes, one needs to know
the characteristics of the building stock in a city. The
job to compile such information for the numerous cities in
worldwide areas of earthquake and tsunami risk is enormous;
too large for engineering teams on foot. Therefore,
WAPMERR is developing methods to derive information on the
nature and height of buildings from satellite images in a
cost-effective way.
The following images show examples of 3D models of parts of
cities.
