| 摘 要： | 本文在分析地形数据的组织方式和LOD模型实现方法的基础上,对于大场景高精度地形数据提出了基于不规则三角网的离散LOD组织存储思路.在不规则三角网数据块的构建及接边、高精度数据的不规则LOD树与普通数据的LOD树的融合等方面做了具体研究,为大场景高精度地形数据的组织存储提供了参考.

| Abstract: | After analyzing the way of organizing topographic data and realizing LOD model,this paper proposed an idea of organizing and storing discrete LOD based on TIN.It concretely researched on the constructing and accessing edge of TIN data blocks,fusing the irregular LOD tree of high-precise data and common LOD tree and other aspects,presented an idea of organizing and storing high-precision topographic data of great scene for reference. |
