摘 要: 在分析矢量数据结构特点、Douglas—Peucker和LZW算法原理及其优点的基础上,提出先用Douglas—Peucker对矢量数据进行有损压缩再用LZW进行无损压缩的压缩流程,取得了很高的压缩比。 The structure of vector data, and the principle of Douglas-Peucker and LZW algorithm are Anlysed. Based on it, an compres- sion flow is proposed, which applying Douglas-Peucker to compress the vector data firstly and the LZW secondly. And the higher compression rate is obtained.
