摘要
应用GIS组件MapObjects开发了吉林公路交通GIS,详细介绍了该系统的数据来源、内容、结构、功能,及其在吉林交通信息管理、交通规划、物流运输等方面的应用。深入探讨了交通地理信息系统中的两个关键技术——空间数据与属性数据的链接和动态分段技术,提出了解决的方法。在此基础上,讨论了交通地理信息系统开发中数据库设计、系统的可扩展性方面存在的问题。
Based on COM technology of GIS the Jilin traffic GIS was developed. The sources of the data, contents, structure, functions of the system were introduced in detailed in this paper. The application of the system to transportation information management, transportation programming and distribution transportation was discussed. Some key problems relating to the spatial data and the attribute data and dynamic segment, are discussed, and the solutions are put forward.
