摘要 根据矢量化地形图数据库文件分布的区域特点,借助分布式数据库的思想,对地形图的数据库文件进行分布式存储,充分利用了计算机网络空间.利用分布式网络计算机并行存储与管理矢量化地形图,解决了矢量化地形图海量图元管理与图形分割的难题,为提高矢量化地形图的管理速度的并行计算提供了技术支持. According to the area characteristic of distributed database files in vector- quantization relief map, in virtue of distributed database idea, we dividedly store the relief map files by making full the space of network. Use the distributed network computers to store and manage vector- quantization relief map. The difficult problem of graphic - primitive management and graphic division is resolved. This model improves the speed of dealing with vector- quantization relief map.
