| 摘 要： | 利用OracleSpatial提供的简单的空间关系查询操作算子，对九交模型所描述的任意两个2维空间不自相交的线目标与面目标（不合空洞）的拓扑关系判断设计了算法，最终进行了试验验证，实现了线目标与面目标间的19种空间拓扑关系的判断。

| Abstract: | This paper designed the algorithm to judge the topological relationships between non - serf- intersection line object and polygon object in arbitrary 2D spaces described by 9 - intersection model using the simple arithmetic operators of spatial relationship query provided by Oracle Spatial. The practical experiment testified that the algorithm realized the judgment for 19 types of spatial topological relationships between line object and polygon object. |
