摘要
随着卫星遥感技术的不断发展,卫星图像的精度和清晰度越来越高,利用公用卫星图像辅助测绘小比例尺地形图成为可能。以某港口工程项目为例,研究利用卫星图像辅助测绘技术绘制小比例尺地形图的方法,探讨其具体操作流程和主要技术问题,提出相关实用性建议。
With the development of satellite remote sensing technology, the precision and definition of satellite image is higher than before. Therefore, public satellite image may be used an assistance to map small scale topographic plan. A port project is taken as an example to research the method to map small scale topographic plan with satellite images auxiliary mapping technique, discuss the operation process and major technical puzzles, and put forward practical advice.
