These last earthquakes provided the opportunity to test the photogrammetric documentation procedure and the information system techniques. After an earthquake, one endeavours to construct new houses for the homeless people as quickly as possible or repair the buildings, which should be restored in a short period. This work has to be done very quickly to avoid other disasters or spread of epidemic diseases. During the renovation of damaged buildings, one of the problems is the rapid determination of the actual state of these buildings. An insufficient determination of damage results can cause great problems later on during preparation and implementation of the renovation project.
