【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。
[Abstract]:Spatial data matching is the basis and key of spatial data updating and maintenance. In view of the difficulty in determining the weights of different matching indexes in spatial data matching, taking the residents as an example, the paper starts with the most basic graphic data difference of spatial data. An automatic method for determining the weight of multi-index geometries matching is established by using the grey correlation analysis method. In this method, the gray relational analysis is used to automatically determine the position, area, direction and other types of the difference weights of the graphical data between the residents, and the comprehensive calculation model of the difference between the graphical data is obtained. The matching result is obtained by calculating the difference of the graph data between the data to be matched. The feasibility and practicability of the method are verified by experiments.
