Google Earth在中老铁路航测外控及GPS控测中的应用

Application of Google Earth in Aerial External Control Survey and GPS Control Survey on Sino-Lao Railway

结合航测外控和GPS控测测量的专业知识,构建Google Earth操作平台,将其应用到中老铁路磨万线航测外控及GPS控制测量的工作之中。充分利用Google Earth提供的卫星影像资源,提取相关地理信息,解决了境外开展航测外控和GPS控制测量工作中的一些技术难点,提高了工作效率。同时简要介绍了操作平台结合航测外控刺点测量的优势。

Combined with professional knowledge of aerial external control survey and GPS control survey, Google Earth service platform is established and used in Sino-Lao railway project. Geographical information is acquired by satellite video resource supplied by Google Earth, which resolves the technical difficulties in aerial survey outside China and working efficiency is greatly improved. A brief introduction is also given to the advantage of combining service platform with external control point survey.
