【摘要】 基于模糊几何理论 ,通过隶属函数的建立 ,首次将矢量 GIS中几何数据的位置不确定性同点与目标间拓扑关系的判定结合起来 ,详细地分析了确定性和不确定性点与含有不确定性的 GIS目标间拓扑关系的判断。并将分析结果应用于区域边界的判定之中 ,以丰富和完善现有区域边界判定的理论和成果更多还原

【Abstract】 This paper integrates the positional uncertainty of geometry data in GIS with the topological relationship among the different spatial objects by establishing the subject function, then elaborates the topological relationship among the point, line and polygon all of which include positional uncertainty, and finally applies the derived results to the determination of region boundaries.更多还原
