Disaster reduction requires the integration of information from diverse sources. Geographic Information Systems (GIS) is one new key technology often used to collect, store, analyse and display large amount of spatially distributed information layers. The core of a GIS is a set of spatially referenced maps, which are stored either as points, lines, polygons or raster data. GIS makes it easy to assign attributes to these spatial quantities and combine different layers of information.
