摘要
为解决铁路勘察设计中前期项目数据缺乏、工期紧张、方案繁多的难题,用空间换时间,建立了"开源地理信息数据获取平台",以开源数字地面模型、卫星影片、河流及路网矢量数据为基础,对全国范围1∶5万精度等高线地形图数据和卫片数据进行预生成,并对预生成地形图数据建立空间数据库,以实现生产任务下达当天即可开始定线的目标响应要求。该平台在方案投标、前期研究等资源受限的情况下,可大幅度提高铁路勘察设计效率,并可为实现智慧铁路提供数据支持。
In order to solve such problems as lack of data,tight schedule and various schemes of preliminary project in the railway survey and design,open source geographic information data acquisition platform has been established by replacing time with space. Based on open source digital ground model,satellite image and rivers and railway network vector data,the data acquisition platform will pre-generate nationwide contour map data with 1 ∶ 50 000 precision and satellite image data and establish a spatial database of pre-generated topographic map data to realize the target response of alignment on the day when the production tasks are assigned. The platform can greatly improve the efficiency of railway survey and design under the condition of limited resources during bidding and early research and provide data support for realizing intelligent railway.
