拓扑关系形式化描述的基本问题与研究进展

A Survey on the Fundamental Issues and Research Progress of Topological Relations

拓扑关系是GIS中空间目标之间最基本也是最重要的关系之一,在GIS空间数据建模、空间查询、空间分析、空间推理、制图综合等过程中起着重要的作用。该文首先介绍了不同的空间数据模型中拓扑信息的表达模式,然后重点回顾和评述了拓扑关系的建模方法以及拓扑关系形式化模型,并探讨了目前研究中存在的问题和有待进一步研究的工作。

Topological relations are one of the most important aspects in GIS modeling,and play the key roles in such fields as spatial data modeling,spatial query,spatial analysis,spatial reasoning,cartographic generalization and others.This paper begins with an investigation of topological representations in vector and raster data models,and then concentrates on the research progress of the formalisms and formal models of topological relations.Finally,some issues are highlighted for further investigations.
