摘要
为满足大比例尺测图现势性的要求,文章提出了利用卫星影像进行航测内业微分纠正测图的方法,通过对其结果进行分析,得出利用该方法获得的大比例尺地形图能满足规范精度要求,且能提高生产效率的结论。
To meet the currency requirements of large-scale mapping,this paper proposes a method that is the use of satellite images to make the aerial differential correction mapping in indoor work. Though analysis of the mapping results, the conclusion is that the accuracy of large scale topographic map obtained with the method can meet the standard requirement,and we can improve the production efficiency.
