Implementing the Web-based 3D Coast Flood Disaster Simulation System

摘要

The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon, tidal wave, flood and storm. Especially, 409 cases, which reach to about 40.9% of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than 40% of the natural disasters that occur every year are happening in coastland. Therefore, there is a great need to construct all related GIS database such as atmospheric phenomena (typhoon, tidal wave, flood and storm), harbor facility, harbor traffic and ebb and flow. Furthermore, the certain system should be developed and integrated with NDMS (National Disaster Management System) by using 3D web GIS technology. In this study, the coast disaster area management system was designed and developed by using 3D web GIS technique so that the coast disaster area could be monitored and managed in real time and in visual. Finally, the future disaster in coast area could be predicted scientifically.
