I think the values in the answer sheet are wrong and dont correspond to the values based on the graphs we get.
For eg, G-Green band , DN is 310, observed value is 0.45. But using the eqn 0.1697*B4 – 7.2858, the value obtained is 45.5212 using the formula, but the value in the answer sheet is 0.456. Also the final spectral signature graph contains values between 0 and 60 whereas in the answer sheet, the values are between 0 and 1. Correction needs to be made. Please clarify if I am getting something wrong
