What does it mean when a satellite has these bands:
Panchromatic: 450-800 nm
8 Multispectral (red, red edge, coastal, blue, green, yellow, near-IR1 and near-IR2): 400 nm-1,040 nm
8 SWIR: 1,195 nm-2,365 nm
12 CAVIS Bands (desert clouds, aerosol-1, aerosol-2, aerosol-3, green, water-1, water- 2, water-3, NDVI-SWIR, cirrus, snow): 405 nm - 2,245 nm
Does it have 4 bands or does it have 29 bands? What does a band physically look like?
