利用灰色关联分析的居民地几何匹配方法
|
摘要
空间数据匹配是空间数据更新与维护的基础和关键。针对空间数据匹配中不同匹配指标的权值确定困难的特点,以居民地为例,从空间数据最基本的图形数据差入手,利用灰色关联分析方法建立一种多指标居民地几何匹配权值自动确定的方法。该方法利用灰色关联分析的方法自动确定居民地实体间的位置、面积、方向等类型的图形数据差权值,得到综合图形数据差计算模型,通过计算待匹配数据综合图形数据差得到匹配结果。通过实验验证了该方法的可行性和实用性。
Spatial data matching is the foundation and key of spatial data updating and maintaining. Considering it is difficult to determine the weight of different matching indexes, a method used to automatically determine the weight of geometrical multi-index settlement matching based on grey correlation analysis was created, starting with graphic data delta. Through measuring and classifying the location, area and orientation delta among the settlement data, the grey relationship of the graphic data deltas was established, and the comprehensive graphic data delta calculating model was built. Finally the matching result was obtained by calculating the comprehensive graphic data delta. The feasibility and accuracy of the method was verified by means of the experiments.
