摘要
文章通过实践,摸索出了基于小比例尺航摄资料进行土方量计算的办法。该方法通过在外业像控、空三加密及立体测图等阶段采取多种提高精度的措施,保证了最后土方量计算结果的可靠性,具有实际可行性,可供同行参考。
This article explores the way of earthwork calculation based on small scale aerial photographic data through practice.By tak-ing many high precision measurements in field works for ground control, encryption of aerial triangulation and stereo mapping stage, ensures the reliability of the final result of earthwork calculation and it is practical, feasible and can be used for referrence.
