Comparison study of merging algorithms in digital map conflation

DENG Su-su,TONG Xiao-hua(Dept.of Surveying and Geo-informatics Engineering,Shanghai 200092,China)  
Map conflation is a methodology to remove discrepancies generating from overlaying two datasets to get a new and consistent dataset.The two phases of map conflation,feature matching and merging,use their respective algorithms.Due to the uncertainty during the matching procedure,some features cannot be correctly matched.Therefore feature merging is needed,which can eliminate inconsistency between two source maps.Several algorithms have been applied in map merging phase,but they have not been systematically compared.Therefore,it is vital to determine the most suitable merging method to attain the best results.It presents some comparing measures,including quantitative and qualitative ones.Through test it analyzes three main algorithms to determine which is the best to be used in map conflation in city area.
