摘要
研究目的:传统的铁路野外地质数据采集使用纸质记录本记录,这种数据采集方式很难满足铁路工程地质信息化的需求。随着GIS+GPS+无线网络一体化技术即移动GIS技术的迅速发展,使得利用移动GIS在野外进行快速、大量的空间数据采集成为可能。因此,本文基于移动GIS技术的铁路野外地质调查系统关键技术及实现方法展开研究。研究结论:(1)基于移动GIS平台,实现了不同数据格式、不同图形系统下的多源数据集成;(2)通过梳理铁路工程地质野外调绘的主要业务流程和采集内容,建立了地质调绘标准化的数据字典,并进行分类编码,有利于实现野外地质数据的快速采集;(3)通过高精度移动定位技术的研究,采用多星多频技术,可以将山区的定位精度提高到1 m以内;(4)该研究成果可以应用于新建铁路的野外地质调绘工作,实现铁路地质调绘的信息化采集,提高工作效率。
Research purposes: Traditional railway field geological data collection uses paper records,which can hardly meet the needs of railway engineering geology information. With rapid development of integrated technology of GIS + GPS +Wireless network,i. e. mobile GIS technology,it is possible to use mobile GIS to quickly and extensively collect spatial data in the field. This paper studies the key technologies and implementation methods of railway field geological survey system based on mobile GIS technology.Research conclusions:( 1) Based on mobile GIS platform,multi-source data integration under different data formats and graphics systems is realized.( 2) Through sorting out the main business processes and collecting contents of railway engineering geology field mapping,a standardized data dictionary of geological survey and mapping is established and classified and coded,which is conducive to realizing data collection of field geology rapidly.( 3) Through the research of high-precision mobile positioning technology,using multi-satellite and multi-frequency technology,the positioning accuracy in mountainous areas can be improved to less than 1 m.( 4) The research results can be applied to the field geological mapping work of new railway,to realize the informational collection of railway geological mapping,and improve work efficiency.
