| Abstract: | 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. |
