【摘要】：空間數(shù)據(jù)匹配是空間數(shù)據(jù)更新與維護(hù)的基礎(chǔ)和關(guān)鍵。針對空間數(shù)據(jù)匹配中不同匹配指標(biāo)的權(quán)值確定困難的特點(diǎn),以居民地為例,從空間數(shù)據(jù)最基本的圖形數(shù)據(jù)差入手,利用灰色關(guān)聯(lián)分析方法建立一種多指標(biāo)居民地幾何匹配權(quán)值自動確定的方法。該方法利用灰色關(guān)聯(lián)分析的方法自動確定居民地實(shí)體間的位置、面積、方向等類型的圖形數(shù)據(jù)差權(quán)值,得到綜合圖形數(shù)據(jù)差計(jì)算模型,通過計(jì)算待匹配數(shù)據(jù)綜合圖形數(shù)據(jù)差得到匹配結(jié)果。通過實(shí)驗(yàn)驗(yàn)證了該方法的可行性和實(shí)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.
