Title: Research on constructing the Geographic Information System of flood prevention decision support
Abstract: According to the current data,the practical application of flood prevention demands and the future development requirements in the lower Weihe River of Shaanxi,this paper took processed and effectively integrated the spatial static data such as the basic geographic information and flood prevention special information and real-time water and rainfall information to develop a flood prevention decision-making supportive geographic information system.The system that integrates the real-time monitoring,3D decision supporting,map querying and positioning,flood prevention preparedness display and gathering and maintaining information was built based on the structure idea of open service-oriented B/S architecture and the database theory of integrative spatial and attribute data and the seamless integration of multi-source data.This paper also discussed some key issues about system architecture design,data organization and processing,database building and optimization,map cache configuration and data sharing and exchanging,etc.These provided the effective guarantee for improving the administrative ability of flood prevention decision,decreasing the flood disaster and building harmonious coexistence between the human and water.
