基于Java3D海量地形数据网络发布

Publication of huge quantities of topograph on web based on Java3D

三维地形的网络发布,涉及数据的实时网络传输、海量地形数据的管理、地形数据的快速更新、与用户实时交互等难题。文中在采用JEE构架的基础上,探讨多比例尺的DEM数据及其相应不同分辨率DOM数据的存储、管理和快速更新,并在此基础上,利用Java3D实现基于视点LOD海量地形数据在网络上实时漫游。

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.
