Question7
The SPOT multi-spectral false color image at the top of the page shows vegetation in red. Vegetation jumps out on the image when compared to the panchromatic image below in gray scale.
The SPOT panchromatic image appears clearer and more in focus and the white areas (sand, roads and buildings) really are contrasted compared with the darker vegetation and water areas. Also, the below ocean surfaces show greater detail.
I think the panchromatic image may be more suitable when measuring beach erosion after a storm or longshore flow given the way the sand jumps out on the image. Aslo, man made structures such as roads appear clearer in the panchromatic image. The multi-spectral color image appears well suited for vegetation studies both on land and possibly at the ocean surface (algae blooms, plankton etc...).
