我处在石太线的测图中首次采用了非标准布点,在保证质量的前提下,减少了外业工作量。取得了一定的经济效益,现介绍如下: 一、内、外业工作中采取的技术措施石太线是晋煤外运的重要通道,它跨越太行山,线路弯曲,全线地形大部分是Ⅱ、Ⅲ级地形,85年航空摄影,像幅23×23cm~2,焦距153mm,航摄比例尺NI测段1:9000,N4～N39测段1:8000,N43～N47测段1:5000,成图
For the first time, I used non-standard layouts in the mapping of Shi Tai Line, reducing the workload of the field on the premise of ensuring the quality. Some economic benefits have been achieved. The details are as follows: I. Technical measures adopted in the field of domestic and foreign businesses The Shitai line is an important channel for Sinotrans to facilitate coal transportation. It crosses the Taihang Mountains and the line is curved. Most of the topography is Ⅱ, Ⅲ Level terrain, 85 years of aerial photography, such as the width of 23 × 23cm ~ 2, focal length 153mm, aerial photography scale NI measurement 1: 9000, N4 ~ N39 measurement 1: 8000, N43 ~ N47 measurement 1: 5000,
