Research and Application on Organization Method Used in 3D Basic Geographic Data

摘要

In recent years, along with digital earth and smart planet concepts launched and the research deepening, 3D GIS as a foundation platform has become a hotspot. The basic geographic data of 3D visualization contains image data and terrain data, how to efficient organize and manage mass geographic data is the key problem of 3D visualization. G/S model is a new type of spatial information network service model. Based on G/S model, a method that realize organization of 3D geographic data by hgml is raised. Finally, an application is used for support our design.
