Abstract: Many countries in the world are effected by disasters. Because of hazard occurrence people lose their houses, forms even their lives. To decrease the disaster impacts on human lives, many organizations are active on disaster risk management. Disaster risk information is spatial in nature and Geographic Information Systems (GIS) plays an important role in disaster risk management. The use of GIS has become an integrated, well developed and successful tool in disaster risk management. However, there are too many GIS-based systems for new GIS users to identify appropriate tools regardless of the usefulness. So, potential users of GIS can catch up to current and latest trends of GIS-based disaster management systems. The main aim of this research is providing an overview of using spatial information in disaster risk management. This study tells us which organizations use GIS for disaster management in South Asia and which disaster phases GIS is applied. In here is tried to answer which GIS data are used in their projects and what type of GIS technologies are applied for disaster management.
Most of the organizations which deal with disaster risk management have projects in pre-disaster phase. Pre-disaster phase is very important and it will be more effective and economical if we pay attention on this phase. Satellite images are used the most of any other GIS data. We compared the GIS technologies, the most of organizations prefer to use web GIS technology. We catch up web GIS may be best choice for new GIS users to apply in disaster risk management. The prepared maps can be available at anytime and anywhere in laptops or mobiles.
