Abstract

The use of remote sensing is becoming indispensable in environmental studies. One of the emerging applications of remote sensing is managing disasters timely and efficiently. The enormous capabilities of remote sensing can be put to use right from the stage of preparedness, planning and mitigation to post disaster relief and recovery. The real time nature of remotely sensed data can be of high value for continuous monitoring and taking necessary actions well in advance. This paper explores the applications of remote sensing and GIS in mapping and assessing multi hazard risks and vulnerabilities. Satellite imageries from various sources are utilized to map the existing landuse/landcover in detail. Geocoded thematic layers are then integrated according to the set parameters to derive multi hazard risks maps. Vulnerability profile is further derived using specific population and properties at risk data. Multispectral and high-resolution satellite images assist in evaluating disastrous events prior to and post occurrence of events.
