This research intended to estimate the dam age information from torrential rainfalls using airphotos and spatial data which have been rapidly increasing their applicability recently. The study area was Bonghwagun of Gyungsangbukdo where the large amount of damages were occurred from torrential rainfall in July, 2008. For this study, the database was constructed for the study area by collecting usable data. The interpretable items from the airphotos of 40§¯ spatial resolution were selected. Also, the useful GIS layers such as road were selected in the digital map to extract the dam age information more accurately and rapidly. The dam aged area was easily identified through the comparison of pre- and post-disaster airphotos. The recovery cost was estimated by applying unit cost to the damaged area. GIS's overlay function was used to extract the damage information of for individual items damaged. The method for extracting damages information using GIS and airphotos could be more efficient and cost effective in case of relatively wide and unapproachable damaged areas. It is also expected that the method using high resolution imagery would lead to m inimize the secondary damages as well since it can facilitate the damage estimation w ithin short period of time thereby supporting early securing budget for recovery. |
