3D-GIS System Research and Development for Emergency Hydrologic Analysis

Abstract

In view of the present situation of frequent flood and drought disaster in China, and lacking of technology for emergency hydrologic monitoring system and emergency response analysis. Face to emergency hydrologic forecast, this paper study on hydrologic information extraction and flood inundation risk emergency, and set up emergency hydrologic analysis system with the function of emergency hydrologic information extraction, flood simulation, flood analysis and hazard evaluation and so on. The system provided technical support and analysis platform for emergency hydrologic monitoring, forecasting and decision making.
