The Ministry of Land, Infrastructure, Transport and Tourism provides assistance to local governments in the event of a large-scale natural disaster. However, we are spending time and effort on investigation and surveying with a dangerout work. In this study, we investigated a disaster area survey using 3D data obtained using UAVs. As a result, while safer and more accurate analysis was possible compared with the conventional method, there were some problems in using different measurement methods according to the type of disaster, and in overlaying and analyzing with the terrain model before the disaster.
