I want to calculate the NDVI and it seems for me that I should convert the values of the 4 bands using the numbers in the band specific metadata. There are two numbers to convert DNs to TOA radiance radiometric scale factor which is a fixed no. (0.01) and reflectance coefficient which is not fixed.
So, should I multiply by both or only use reflectance coefficient?
and what is the difference between analyticMS and analyticMS_SR images?
