摘要
介绍了利用遥感图像处理软件ERDASIMAGING 8.6对西宁市卫星影像及地形图进行选择、几何精校正、图像合成、图像镶嵌的方法,结果表明:多项式法对地形较平坦地区的卫星影像纠正具有较高的精度,为遥感影像的进一步处理提供数据。
The method on the selection of the satellite images and topographic maps, geometric precision correction, image composition, image mosaic were introduced and tested in the paper with the software ERDASIMAGING 8.6. The result shows that the rectification precision of satellite image in flat area with the multinormal method is perfect and this will supply the data for remote sensing image processing further.
