Feature Point Selecting of Vector Curve

WANG Yan-min(Dept.of Surveying and Mapping,Heilongjiang Institute of Technology,Harbin150008China)  
The problems of data reduction of vector curve are discussed.Douglas-Peucher Algorithm is introduced,its advantages and disadvantages are pointed out.A improved Douglas-Peucker algorithm is developed.It will greatly raise the running velocity.A new algorithm-point by point forward is pro-posed.It is indicated by experiment that the fidelity and velocity are greatly superior to others.
