Application of automatically broken line in line factor merging

FANG Peng-cheng,CAI Xian-hua(Department of GIS,Transportation College,Southeast University,Nanjing 210096,China)  
This article introduces scanning junction method and discusses with emphasis the application of the broken line method automatically in the striation essential factor merge,based on describing in detail the automatically broken line method of the establishment of line factor's topology and arc topology. Through two steps of intersection merging automatically and line factors's mutual intersection,introduces pretremeat before intersection,improving the efficiency of cutting line automatically. Finally make a simple experiment.
