Question 2 |
Spectral Profiles for Rock, Vegetation, and Manmade (Road). For the Vegetation (green line) the Reflectance is high for Near IR vs low for Visible (This is the basis of NVDI=NIR-Red/NIR+RED=1). For the Road, the you can see the reflectance doesn't change much for wavelength > RED (NVDI=0). For the Rock (orange line), the Reflectance gradually increases with wavelength. (NVDI would approximate to around .5)

Question 3 |
Noise Bands:
Band 1-3 (370.43-390.09 nm): The image for this band is all black.The spectrum shows no reflectance.
Band 108-113 (1365.24-1415.07 nm): The image for this band is all black.The spectrum shows no reflectance.
Band 153-161 (1813.16-1880.96 nm): The image is black Band 162-164 (1891.03-1911.15 nm): There is a large "spike" in this band when looking at the spectrum. When looking at images for these bands it looks "speckled". Band 165-166 (1921.21-1931.27 nm): Here is still speckled but you can make out the the large features like the mountains/lake.
Band 222-224 (2490.29-2510.10 nm): Band 222 is speckled and 223-224 is black.
