Research on area features' data matching technology based on topology relations

GUO Li,CUI Tie-jun,WANG Hao,GUO Jian(Institution of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
Data matching technology plays a key role in geospatial data integration and fusion.In this paper,we define the rate of overlapped area by geometry measurement based on the description of area topology relations in 9-intersection model.Then,we put forward a way of data matching based on the rate of overlapped area,and realize area features matching of 1∶1,m∶1,m∶n.At last,we take large scale residential area data as an example to test the algorithm of data matching for area features based on the rate of overlapped area,and bring forth the relevant results.
