我国的铁路航测通常是一次摄影,目的是为了解决初测选线,提供初测地形图。因此需要在方案研究报告的基础上再深入研究初测阶段值得比较的线路方案,明确需要航摄的方案,然后进行航带设计,作为航空摄影的依据。根据以往铁路航测的实践,在航带设计工作中往往碰到一些具体的问题,如有的线路航带设计只考虑线路弯曲的情况,测段布置过于零碎,不利于航摄飞行,民航航测队提出意 China’s railway aerial survey is usually a photography, the purpose is to solve the first test line, to provide the first test topographic map. Therefore, it is necessary to further study on the basis of program research reports worthy of comparison of the initial test phase of the line program, a clear need for aerial photography program, and then the band design, as the basis for aerial photography. According to the previous practice of railway aerial survey, some specific problems are often encountered in the design of the navigation strip. For example, some of the design of the navigation strip only considers the bending of the line, the measurement layout is too fragmented and is not conducive to the aerial photography flight.
