铁路地理信息系统数据获取技术

系统论述了铁路地理信息系统(RGIS)数据获取的方法,这种基于现代测绘高新技术的方法,对克服传统数据获取中劳动强度大,工作效率低,对行车干扰大等缺点有重要意义.针对RGIS中包含的空间信息具有目标众多,管理对象量大、面广、复杂、线长、静态与动态数据相结合等特点,提出了铁路地理信息系统数据获取中一些值得研究的问题.

The Data Capture Technologv of RGIS

In this paper, the methods of Railwav Geoaraphic Information Svstem(RGIS) have been discussed , these methods, based on the high technoloav of survevina and mappinq, have profound sianificance in reducinq the labor intensity in the RGIS data collection . It is also of oreat value in improvina work efficiency and overcominq the obstruction to the movina train. In view of the characteristics that RGIS includes such as the multiple objects, the oreat volume and wide ranqe of manaqement involved, the complexity, the length of railway line and the combination of static and dynamitic data, some valuable opinion of data capture in RGIS has been proposed.
