拓扑关系是地理信息系统的基本主题之一,在数据组织和空间分析中得到了广泛的应用。似乎在某些情况下,简单的拓扑关系很难表示复杂的空间情况。不同的拓扑关系可能会导致一些拓扑关系模型的相同表达,其中9-交模型(9IM)及其扩展模型是众所周知的。为了更准确地描述直线和区域之间的复杂拓扑关系,本文提出了一种详细的拓扑关系模型和计算方法。最好是回答这个问题,例如,“这条路怎么穿过公园的?”开发的程序用于计算线和区域之间的复杂拓扑关系,以及需要从其中减去相关线状要素面积的土地利用地块的实际面积。
Topological relation is one of the basic topics of geographic information systems (GISs), and it has been widely applied in data organization and spatial analysis. It seems whether a simple topological relation can hardly represent complex space situations in some cases. Different topological relations may result in the same expression by some topological relation models, among which the 9-Intersection Model (9IM), and its extended models are well known. In this paper, a detailed model and calculation method for topological relations are proposed, to describe the complex topological relations between lines and regions more exactly. It is better to answer the question, e.g., “How does the road cross the park?” The programs are developed to compute the complex topological relations between a line and region, and the actual area of land use parcels, from which the area of related linear features wait to be subtracted.
