| Abstract: | Publication on web of topograph will encounter the following problems ; data real-time transmission on web, managing and updating of huge quantities data, real-time interactive, etc. On the basis of JEE framework, the paper studies storage, management and updating of the data of multi-scale DEM and multi-resolution DOM, and the author realizes the publication on huge quantities of topographic roaming based on sight LOD using Java3D. |
