几十年来,我国公路勘测部门一直沿用传统方法测设公路。无论是踏勘还是选线都靠技术人员在现场奔跑。野外工作时间长,劳动强度大,进度慢,工效低。而且受自然、地理条件限制多,实难进行多方案比较。选定的路线未必是最优方案。科学技术发展的今天,航测作为一个可加快公路测设速度、提高测设质 For decades, China’s highway survey department has been using the traditional method of measuring roads. Whether it is reconnaissance or alignment by technicians in the field run. Long working hours in the field, labor-intensive, slow progress, low efficiency. And by the natural and geographical conditions and more difficult to carry out multi-program comparison. The selected route may not be the optimal solution. Today’s science and technology development, aerial survey as a can speed up the highway survey set speed, improve test quality
