摘要研究目的：随着测绘卫星遥感技术的发展 ,卫星影像分辨率不断提高 ,卫星立体像对的获取为航测制图提供了新的数据源。但如何实现卫星影像制图 ,为铁路勘测设计服务 ,需在理论研究和精度分析的基础上 ,采取有效的技术措施 ,制定合理的制图方式。

研究结论：通过研究并结合成绵乐、兰州至重庆和成都至兰州等铁路勘测设计制图试验 ,证明1.0m的IKONOS卫星立体像对基本满足铁路1∶2 000地形图制图要求; 2.5m的IRS-P5卫星立体像对基本满足铁路1∶10 000地形图制图要求; 0.6～1.0m、2.5m分辨率卫星影像基本上分别满足铁路1∶2 000、1:10 000地形图修测的平面精度要求。

Abstract：Research purposes：In recent years, resolution of satellite images has been improved gradually with the development of satellite remote sensing technology. In particular, the acquisition of satellite stereograph provides a new data source for aerial mapping. At the same time, effective technological measures and reasonable mapping methods are required on the base of theoretical study and accuracy analysis, to achieve the satellite image mapping technology servicing the railway survey and design.

Research conclusions：The researches and tests on Mianyang-Chengdu-Leshan Railway, Lanzhou-Chongqing Railway, Chengdu-Lanzhou Railway and so on prove that IKONOS Satellite images with resolution of 1.0 meter can basically meet the topographic mapping requirement of a scale of 1∶2 000. IRS-P5 Satellite images with resolution of 2.5-meter can meet the topographic mapping accuracy requirements of a scale of 1∶10 000. Satellite images with resolutions from 0.6 to 1.0 meter and 2.5-meter can respectively meet the plane requirements of topographic map revision for a scale of 1∶2 000 and 1∶10 000.

Key words： high-resolution satellite image aerial surveying topographic map revision railway survey and design
