| 摘 要： | 通过对现有3维地形环境的LOD分块方法和矢量地图的多比例尺结构的比较分析,提出了一种按照地形数据的经纬度差异与矢量地图各比例尺的经纬度差异进行比较结合的方法。该方法不仅有利于对影像栅格数据和矢量数据的调度,而且还为两种数据同时叠加在地形上打下了基础。最后通过实验,验证了这种方式的可行性。 |

| Abstract: | Based on comparing and analyzing the existed LOD block partition method and multi-scale structure of vector map in 3D terrain environment,this paper put forward a comparison and integration method according to the differences of longitude and latitude of terrain data and the differences of longitude and latitude of multi-scale vector map.This method is not only beneficial to the scheduling of raster map and vector map,but also provides the foundation for overlapping these two kinds of data on terrain data.Finally,this paper verified the feasibility of this method by experiments. |
