摘要
利用卫星图像修测地图时,首先对卫星图像的大地坐标、投影性质等进行设定,使其与地图相统一,然后利用地图对卫星图像进行几何精校正,最后把卫星图像和地图叠加在一起进行转绘。实际工作表明,与传统外业测量方式相比,利用此技术修测地图更加方便、高效,且制作的地图具有较高精度,能较好地满足地图修测工作需要。
When mapping with satellite image, firstly, set the coordinate and projection of the satellite image with those of the map. Secondly, do polygonal correction to the satellite image with the map. Finally, cover the map with the satellite image rightly, and then begin mapping. It is proved that this method is efficient and can meet the need for precision.
