Remote sensing and GIS contribution to the detection of areas susceptible to natural hazards in the Safi area, W-Morocco

The quality, data amount and information content of GeoInformation Systems (GIS) dealing with natural hazards and vulnerability assessment has increased considerably during the last decades. Meanwhile many countries have implemented such a GIS for the public use, whereby satellite imageries before and after disasters form important layers within these GIS. In the scope of this research adaptation strategies are developed by presenting an approach in which Geographic Information Systems, used together with remote sensing data, contribute to the analysis and presentation of information, especially required for the increasing geo-hazards in Morocco, such as earthquakes, mass movements and flooding using mainly free available, existing data for contributing to a GIS integrated data base.
