摘要
提出了8种分割度量和4种区域间的距离度量,并通过这些度量对传统的拓扑关系模型9交集模型进行扩展:用度量值替换9-交集矩阵中相应的元素,表示对应的度量属性,将度量关系和拓扑关系有机结合起来。扩展后的9-交集模型能同时表达拓扑和度量信息,增强区域间关系的表达能力,扩展了模型本身对拓扑的表达能力;并且提高了空间数据查询的准确性和效率,同时也更符合人类的认知。
In this work,eight types of segmentation measure and four types of interregional distance measure were proposed.Based on these measures 9-intersection model was extended.The measure value was used to replace the corresponding element in the 9-intersection matrix to show the measure property;the measure and the topology were combined together.The extended 9-intersection model can express both topology and measure information simultaneously,while enhances the expressive ability of the interregional relationship,furthermore,improves the expressive ability of topology.It also improves the accuracy and efficiency of spatial data querying,meanwhile,it more fits human recognition.
