Abstract:

Map object matching as an indispensable process in spatial data integration and updating has important researching significance. Root Mean Square Error (RMSE) as a numerical indicator that measures map accuracy and quality , its range is as one of the important standards in mapping and cartography generalization, and commonly used to balance the quality of spatial data, The data of different scale or sources are varying in size and threshold of the RMSE. Polygons occupy a much proportion in a map, this paper introduces the RMSE in the process of areal feature matching, combined with the clustering algorithm of adjacent Polygon to match areal feature. It can effectively solve the problems for dertermining the threshold and many-to-many relationship in the multi-scale spatial areal feature matching, the experimental results show that this method is stability and reliability.
