航空勘测是综合性的先进勘测技术,采用航测方法可以提高勘测设计的质量和效率。在铁路基本建设中大力推广应用航测与遥感技术是实现铁路勘测设计现代化的一项重要技术政策。二十多年来,在铁道部领导的重视下,铁路航测从无到有,从小到大,为新建铁路航测设计及营业线技术改造和管理提供了大量基础资料。航测在铁路建设中的作用日益提高,目前新建干线勘测选线多数已采用航测。二十多
Aviation survey is a comprehensive advanced survey technology, using aerial survey method can improve survey and design quality and efficiency. It is an important technical policy to modernize railway survey and design to promote the application of aerial survey and remote sensing technology in railway infrastructure. Over the past 20 years, under the supervision of the leaders of the Ministry of Railways, there has been a great deal of basic information provided by the railway for aerial survey from scratch, from small to large, providing technical basis for the design and operation of the new railway aerial survey. Aeronautics and astronautics are playing a more and more important role in railway construction. At present, most aerial survey and survey lines have been aerial surveyed. More than twenty
