SPOT-XS imagery data covering the southwestern corner of the Inland Niger Delta of Mali were acquired on three dates in 1988. These ...
A simple method for reducing the effect of cloud on satellite thermal imagery, while preserving full temperature and spatial resolution, is presented. The method makes use of the correlation between apparent thermal and visible radiances in an area contaminated by thin or patchy (subpixel) cloud....
