| Abstract: | During the vectorization of scanned map,it is difficult to extract the crossing and conglutinating map elements automatically.Aiming at this characteristic,an automatic extraction method for map elements based on splitting and combining was proposed.This paper also designed each step of this method,studied the optimization of the key technique about thinning and tested the validation of the method by programming. |
