Abstract: 缩编更新是当前GIS多尺度数据库更新的重要技术途径之一。针对我国国家1∶5万数据库更新工程的实际需求,研究分析了用较大比例尺新道路数据缩编更新较小比例尺道路数据的总体思路,提出了基于网眼密度的道路选取和顾及层次分析的道路匹配方法,实现了道路数据缩编更新的自动综合处理,并在1∶5万数据更新实践中进行了实验验证。
Geo-spatial data updating based on map generalization is one of the important ways for GIS data updating.This study is focused on the approach for road data updating based on map generalization.The selection method for road data based on mesh density and road matching method considering the levels analyses is proposed for this procedure.This approach is applied in the project of national GIS data updating at 1∶50 000 scale,and the results shows its feasibility.
