| 摘 要： | 以计算几何模型为基础,结合对人们在相互交流中所涉及的拓扑关系分析,本文将线状与面状要素的拓扑关系概括为19种形式,并建立了15种量化指标对其进行细化描述,给定了这19种拓扑关系与15种量化指标的依赖关系,规范了15种拓扑关系量化指标的应用条件,最后对所提出的拓扑关系及其量化指标模型实施的可行性进行了分析。文中所提的拓扑关系描述深化了GIS平台的信息查询,并对查询语言的改进具有借鉴价值。

| Abstract: | Based on computational geometry, and combining with the view from the analysis of topological relation among people, the paper classifies the topological relation between linear and area object into 19 kinds firstly. Then, it constructs 15 kinds of geometric metrics to describe the topological relation. In addition to, it studies the dependencies among the topological relations and the metric parameters. At last, it makes the feasible analysis. Study shows that the models can deepen information query of GIS, and have value in improving query language of GIS . |
