时空一体化GIS-T数据模型与应用方法
An Integrated Spatio-Temporal Data Model for GIS-Transportation and Related Applications
-
摘要: 在介绍与交通地理信息系统(GIS for transportation,GIS-T)相关的概念的基础上,归纳了GIS-T数据模型的发展和已经取得的主要成果,重点讨论了时空一体化GIS-T数据模型的基本框架。该模型着重解决了动态交通信息与道路网几何数据的一体化时空建模问题,并且进一步分析了GIS-T的基本技术方法,探讨了GIS-T的若干典型应用,并对该方向今后的研究进行了分析和展望。Abstract: The latest research activities is summarized and outcomes of GIS for Transportation(GIS-T) data modelling following the associated concepts of GIS-T are presented.An integrated spatio-temporal framework for GIS-T data modeling is proposed,which fits well for modeling of dynamic traffic information and road network data.Before
