The idea is therefore to acquire the data with a non-tactile measuring technique (photogrammetry) and to combine all information in a GIS. A GIS has the primary feature of being able to store objects having both geometric and thematic features and allows automatic evaluation and analysis of the information. The data management in a GIS relies on a detailed data model. In the case of the documentation of earthquake damages, it has to integrate all the damage indicators and factors, separately for each possible building type.
