System: Windows 7
Software: Arcmap 10.4.1
Data: Landsat 8, NDVI calculations
I am attempting to calculate the NDVI values over my state over a period of 3 months. Naturally, there are going to be clouds in my image. I am aware that there are ways to correct for cloud interference (using the QA band, Fmask) but I'm not sure exactly how I should approach it. My plan was to use Landsat 8 bands 5 and 4 on their own but I'm unsure if I should apply corrections before or after calculating the NDVI. Would it be better to run corrections then the NDVI or vice versa? Does the order matter?
