由于线性参考系统和动态分段技术在铁路等线性要素处理的过程中具有的优越性,使得现行的大多数铁路地理信息系统(GIS)都加入了这两项技术。本文探讨了线性参考系统和动态分段技术的基本概念,介绍线性参考技术在铁路供电GIS中的应用。
Due to the superiority of linear reference systems and dynamic segmentation in the processing of linear elements such as railways, most of the current railway GIS systems have been added to these two technologies. This paper discusses the basic concepts of linear reference system and dynamic segmentation technology and introduces the application of linear reference technology in railway power supply GIS.
