摘要
为了解决水利移民工程中数据量大、管理难、表现效果不佳以及难以支持决策等问题,设计并开发了基于三维地理信息系统World Wind的移民信息系统。对移民信息系统的体系结构与功能模块进行设计,基于WorldWind组件对系统进行开发,实现数字高程模型(DEM)及影像数据的划分、存储、组织与调度,在此基础上对移民信息进行集成与应用。实例表明,该系统具有较好的扩展性和三维效果。
To solve the problems of huge storage,difficult management,poor display of data and decision support,a Migration Information System（MIS） based on three-dimension GIS named World Wind was designed and developed.Its system architecture and functional modules were designed,MIS was developed based on World Wind Java SDK,Digital Elevation Mode（DEM） and image data were divided,stored,organized and scheduled,based on which integration and application of migration information were accomplished.A case study shows that the system has good extensibility and 3D effect.
