摘要
陆地卫星TM图像含有丰富的光谱信息,SPOT全色波段图像数据分辨率较高,因此,如何将这两种图像数据有效地结合起来,在遥感应用领域中显得越来越重要。本文研究了SPOT和TM图像数据的数字复合方法。结果表明,复合后的图像提高了分辨率,增加了光谱信息。
Landsat Thematic Mapper (TM) image is rich in spectral information, while SPOT panchromatic data is fine in its spatial resolution. Complementary and effective use of these data has shown in its increasing importance in the field of remote sensing application.In this paper, methods of digital merging of SPOT and TM data are investigated. Resultant of enhancement both in spectral and in spatial resolution is illustrated by an example.
