FIGURE 2.6 Band 2 (red) of a SPOT-5 image from June 19, 2005 (resampled from 10 to 1 m,
left) and IKONOS/SPOT-5 fusion result (right). Despite the scale ratio of 1 : 10, the fusion still
produces a good-quality image with spatial improvement and spectral fidelity.
FIGURE 2.7 Band 2 (red) of SPOT-2 image from April 21, 2005 (resampled from 20 to 1 m,
left) and IKONOS/SPOT-2 fusion result. Spatial features are mostly from the panchromatic
image and due to the scale ratio of 1 : 20 it is hard to judge the spectral quality. Still, the fused
image shows a lot of improvement over the original.
