Spatial resolution improvement of MeRIS images by fusion with TM images

The medium resolution imaging spectrometer (MeRIS) is ready to be launched. Considering its spatial resolution (240 m), potential users will have to face the mixed pixel problem. The authors propose to improve its resolution by merging MeRIS images with Landsat TM images. The best characteristics of the two images (spatial, spectral, temporal) are then preserved.
