面向防汛的三维预警监视平台研究与应用
Research and application of 3D Early Warning Monitoring Platform for flood prevention
摘要
Abstract
For overcoming the shortages existed in the present flood information management system such as difficulty in integrating multi-source information, and insufficient timeliness and expression capacity, a 3D early warning monitoring platform （3D-EWMP） has been designed and developed on the base of 3D geographic information system WorldWind. Four-layer system structure consisting of data layer, server lay- er, application layer and client layer was proposed, the application layer function module and basic compo- nent architecture were designed, basic component data was effectively organized and managed using tile pyr- amid technology and quad tree structure. The 3D visualization environment was set up, geospatial informa- tion of flood control was integrated into the platform by Web Map Service （WMS）, and multi-source infor- mation integration of flood control was proposed. Application of the 3D-EWMP in flood control and drought relief decision services platform of Shaanxi Province shows that the platform designed has integration of mass data, good practicability, expansibility and 3D expression, which could provide decision-making sup- port for flood control.关键词
