Recently, large-scale natural disasters have frequently hit our life from extreme climate change. Especially summer typhoons and regional downpours have caused more flooding damage than ever before. To effectively prevent the natural disasters, it is required to establish an emergent information system making use of spatial and geographical information and the state-of-the art technologies such as GIS, IT and Remote Sensing. In addition, it is necessary to overcome the limits of the existing two-dimensional GIS and to respond to various, complex demands from users. Accordingly, this study was aimed at making Database about damage information with the use of high-definition spatial images and field investigations, and thereby at expressing three-dimensional information on the damage beyond the existing two-dimensional information. This study had been conducted on the region at Seobyeok-ri, Bonghwa-gun, Gyeongsangbuk-do, which suffered a massive damage caused by downpour at the end of July, 2008. Based on the investigation, this study explored the status of relevant damage, and divided the damage according to the "2008 Guidelines on the investigation of natural disasters and the establishment of restoration planning." In addition, it extracted contour lines and elevation points from a 1/5,000 digital topographic map to create a digital elevation model (DEM), and with the use of the height values in the DEM, it produced a three-dimensional disaster simulation of the damaged region. Therefore, it is determined to allow the public to raise awareness on the disaster due to its realistic description and to help policy makers make a decision on relevant issues.
