Description: 在计算机地图制图的过程中，通过各种手段获取的矢量数据往往存在各种各样的问题，需要对数据进行预处理，数据压缩是其中的一种处理方法。在计算机地图中，数据压缩的对象是线状要素中心轴线和面状要素边界数据(几何数据) ，本程序名称为道格拉斯－普克算法．-computer cartography in the process, through various means to obtain the vector data exists in a wide variety of issues, the need for data preprocessing, Data compression is one of these options. In the computer map, Data compression is targeted at the center axis of linear elements and the elements of the border facial data (geometric data) The procedure known as Douglas-Puke algorithm.
