摘要
利用现势的高分辨率遥感影像,经过精确的多项式变换正射几何纠正后,得到正射影像(DOM)与原有的数字线划图(DLG)叠加,经判读识别地物的变化,实现对原有地形图的快速更新。通过对地面控制点和检查点纠正的精度分析说明,利用QuickBird遥感影像数据在地势较为平坦的城区更新1:2000比例尺的地形图是可行的。
Urban large-scale topographic maps can be fast renewed by means of overlapping the original digital line graph (DLG) and up-to-date remote sensing images of high resolution which has been geometrically rectified in orthography with the precise polynomial transformation. Quick Bird panchromatic remote sensing image is used, which is suitable for renewing 1:2000 scale topographic maps in an urban area with even terrain.
