摘要
提出了河道断面转化为地形图的方法,并利用已有潮白新河19+000~24+150段断面资料,通过内外业结合的方式,成功的将河道断面转化为1:2000地形图。证明了该方法不仅保证了1:2000地形图的测图精度,而且还提高了工作效率、降低了外业劳动强度和节约了生产成本。
The method of river section transformed into topographic map is put forward,and using the data of Chaobai river′s section from 19+000 to 24+150 segment,the river section transformed into 1:2000 topographic map is successful combining inside and outside work.It proves that the method not only guarantees the mapping accuracy of 1∶2000 topographic map,but also improves work efficiency,reduces field labor intensity and saves the cost of production.
