| Abstract: | In the case of complete information and reduce the amount of data on spatial data processing,data management and transmission of great significance.This paper analyzes the existing Douglas-Puke（Douglas-Peucker） data compression algorithm,a simpler feature extraction method,the algorithm to vector data coordinates information to slope constraints.Through simulation,the algorithm in extracting feature points vector curve over the course of Douglas-Peucker algorithm is simpler,complex curves of feature extraction is also very accurate. |
