针对拓扑检查算法复杂、计算量大，串行计算已远不能满足海量地籍数据高效拓扑检查需求的问题，在分析了点线拓扑关系的并行特点基础上，将界址点的数据划分方法与界址线的Q&R空间索引方法相结合，实现了界址点与界址线的并行拓扑计算。用某地区实际的界址点集与界址线集对点线拓扑并行检查进行实验。测试结果表明：并行检查算法的并行效率随着进程数的增加而有所衰减，但稳定在30%以上，加速比达到5以上，且相比于ArcGI...
将地籍地块间空间拓扑关系的判断分为2个层次来处理:2个简单地块间空间拓扑关系的判断;1个简单地块与1个复合地块间空间拓扑关系的判断。2个简单地块间空间拓扑关系的判断可直接利用Oracle Spatial提供的空间关系查询操作算子来实现;复合地块和简单地块间空间拓扑关系的判断,按照双四元交模型(D4I)的思想,将其转化为2组简单地块,然后利用Oracle Spatial的空间关系查询操作算子来处理。...
