摘要
介绍了目前在交通地理信息系统(GIS-T)领域常用的几个数据模型,并探讨了各个模型的特点和在表达交通信息时的缺陷,提出基于三维GIS-T时空数据模型是该领域的发展趋势。
It presents several data models in GIS-T, such as non-planar data model, linear reference and dynamic segmenting data model ,lane-based data model and object-oriented data model, and discusses the features of each model and the limitations in representing transportation information. On the basis of synthetical analyzing, it points out that the space-temporal data model is the future developing trending of GIS-T.
