摘　　要：采用OSG开发技术实现南海岛礁三维地理信息系统主要功能。采用LOD技术和数据动态加载技术提高了系统海量数据的处理效率,实现了海量地理信息数据的动态显示和漫游。融合基础DEM数据、高分辨率遥感影像数据、三维模型数据,实现了基于三维可视化空间的信息查询和多媒体信息的显示及空间分析等地理信息系统功能,达到了良好的效果。This paper introduced the method to develop three-dimensional geographic information system of South China Sea reefs using OSG.The LOD technology and data dynamic loading technology have improved the efficiency of massive data processing,and made massive GIS data display and roam dynamically.This system integrated DEM data,high resolution remote sensing image data,and three-dimensional model data.It had the GIS functions of multimedia information display,spatial analysis,and information retrieval which is based on three-dimensional visualization space.The result showed that the system works well.
