摘　　要：新建铁路项目前期投入较少的人力、物力,缩短项目周期是设计单位所需解决的问题,因此选线过程中快速生成多方案的地形DEM数据模型尤为重要。Global Mapper软件作为一款小型地理信息软件,应用软件专题地图制作功能,可绘制项目地理位置示意图、线路平纵断面缩图,易于操作,出图效率高。该软件支持栅格、矢量、高程数据等多种显示和处理,应用全球免费的STER数据,可以高效生产研究区域内的DEM高程模型,能够达到铁路项目预可研以及部分项目可研阶段的精度要求,具有实用参考价值。Quick generation of multiple terrain DEM data models during the route section is especially important to invest less manpower and money and shorten the project period in the earlier stage of newly-built railway project for design company. Global Mapper software as small geographic information software can draw the project location map and thumbnails of plan and profile of line by using thematic mapping function of software and is easy to operate is high in efficiency. The software supports such various displays and processing as raster, vector and elevation data, etc. , and may generate efficiently the DEM elevation model within the study area by applying the global free STER data. The precision of the model can meet the requirements in the pre-feasibility study stage of railway project and feasibility study stage of some projects, which has practical reference value.
