两种地图点群综合算法的比较

摘要

通过搭建实验程序，分别对基于非加权Voronoi图和加权Voronoi图的点群自动综合算法进行验证，详细对比和分析两种算法计算结果对点群的统计信息、拓扑信息、度量信息和专题信息的传递情况，计算部分结果的相似度，从而得出加权Voronoi图点群综合算法更优的结论。%A test program is build up ,in which the OVD‐based and MWVD‐based algorithms for point cluster generalization are verified . T he statistical , topological , metric and thematic information transmissions during the process of generalization are analyzed in details .The similarities of some of the results are also calculated ,thus the M WVD‐based algorithm is proved to be better .
