摘　　要：在简要介绍Google Earth软件和基于Google Earth开发的选线设计软件GERail的基础上,阐述上述软件应用于铁路前期规划中线路方案设计、比选和方案汇报演示中的优势,为研究线路方案、弥补地调资料缺陷、判识地质情况、绕避不良地质区域、提取地形数据、建立数字地面模型以及为线路设计评审和决策提供了一个直观平台。同时还总结了座标系转换、局部区域的地形高程失真等软件应用中应注意的问题。Based on a brief introduction of Google Earth software and CREC＇s Google Earth based railway route location software GERail, Description is provided to the advantages of above software used in railway line pre-planning and design, railway line program comparison and location, and program demonstration, by which an ocular platform is built for studying route location, making up defect of geological investigation information, discerning geological conditions, bypassing unfavorable geologic province, collecting topography data, setting up digital terrain model and reviewing and approving line design. Meanwhile, problems attracting attention in software application such as coordinate conversion and local terrain elevation distortion are summarized.
