摘要
介绍了基于特征的GIS概念,在剖析传统GIS的“弧段-结点”数据结构用于交通网络分析主要缺陷的基础上,提出了基于特征的GIS-T非平面数据模型,并尝试构建该模型,从而使得原本难以满足复杂现实交通网络模拟和分析要求的数据结构得以改变。
This paper introduces the concept of feature-based GIS and,based on the analysis of the main limitations of traditional″arcs-nodes″GIS data structure used in the traffic network anal-ysis,puts forward a feature-based non-plane GIS-T data model.In order to change the original data structure unable to satisfy the needs of the complicated realistic traffic network simulation and analysis,the authors also try to construct the feature-based non-plane GIS-T data model.
