论述了经典的道格拉斯—普克压缩算法,分析将其应用于多边形边界数据压缩所<br>造成的图形失真现象,提出了一种增强型道格拉斯—普克压缩算法,并用实际的MapInfo 矢量数据来检核该<br>算法的可靠性。-Discusses the classic Douglas- Puck compression algorithm, the analysis applied to the boundary polygon graphics data compression, distortion caused by the phenomenon, proposed an enhanced Douglas- Puck compression algorithm, and use the actual MapInfo vector data to review the nuclear to the algorithm.
