摘要 随着传统GIS向网络GIS的发展,地图的更新通常需要网络中多个站点相互协作完成,传统的并发控制策略不能很好满足协同GIS中多用户协作感知的要求。为此提出了基于四叉树索引的区域版本并发控制机制,并给出了基于四叉树索引的区域版本实时协同绘图系统的框架和相关问题的解决方案。 As the traditional GIS develops towards Internet GIS, the update of maps usually needs the integrated cooperation of several websites. The traditional concurrency control strategy does not satisfy the collaboration awareness of multi-users in cooperative GIS. Therefore, regional version concurrency control strategy by quadtree index was suggested, and its frame and methods for correlative issues were given.
