| 摘 要： | 针对WebGIS多尺寸三维景观地图数据处理问题,提出了一种高速数据索引结构MSORQ-Tree。根据该索引的算法,得出移动WebGIS景观图,将该索引和其他索引进行性能比较。结果显示,基于金字塔分割规则的区域,进行分割四叉树所获取的MSORQ-Tree高速索引可有效处理WebGIS中海量景观地图数据。

| Abstract: | For WebGIS multi size 3D landscape map data processing problems, this paper proposes a high speed data index MSORQ-Tree structure, Based on the algorithm of the index, the mobile WebGIS landscape diagram can be acquired, it compares the performance index and other index. The Results show that the area based on pyramid Segmentation rules, dividing a quadtree MSORQ-Tree high speed index can be obtained and can effectively deal with massive landscape map data in WebGIS. |
