摘要
提出了一种线与多边形矢量数据的压缩方法，并在此方法的基础上提出了基于非拓扑关系的穷举搜索压缩法。利用MapInfo交换格式矢量数据进行实验，结果表明，使用该方法数据压缩量大、逼真度无明显变化且运算速度快。
A compression method of the line and the polygon vector data is given in this paper. At the foundation of this method, the compression method of the all-list-search which is based on non-topology relation is put forward. With the experiment of the MapInfo exchange format data, the results illustrate that this compression method has the characteristics of large data compression ratio, high accuracy and fast operating speed.
