摘要
航空摄影测量是长距离油气管道工程线路地形图测量的常用方式,RTK测图和全站仪测图用于管道单体工程测量。RTK测量凭着灵活、方便、快捷等诸多优势,在平原、丘陵、沙漠等地区发挥着重要作用,而免棱镜全站仪测图则在密林、悬崖、沟壑等区域受到重视。结合工程实践,通过RTK与免棱镜全站仪测量成果精度与测图效率的比对,分析总结免棱镜全站仪在高海拔山区进行大比例尺测图的优越性。
The aerial photogrammetry is the common measurement methods of the long distance oil and gas pipeline engineering survey, RTK mapping and total station mapping pipeline used for single project measurement. RTK measure- ment is flexible, convenient, fast and many other advantages,is playing an increasingly important role in the plains, hills, desert area, no prism total station mapping technology is more important used in the forest, cliff, gully region. Combined with the engineering practice,through RTK mapping and no prism total-station mapping efficiency comparison, analysis and summary the superiority of no prism total-station instrument used of large scale mapping in high altitude mountain.
