Though EVI coefficients have not been developed for Sentinel 2 imagery, I am using the same coefficients used for MODIS to calculate EVI for Sentinel imagery.
I know that Sentinel 2 imagery is TOA reflectance and has a scaling factor of 10000. Hence, can I use the following formula to calculate EVI
(2.5* (NIR/10000-red/10000))/(NIR/10000+(6*red/10000)- (7.5*blue/10000)+1)
I did the above calculation in Arcmap and QGIS but got completely different results- QGIS gave me a plausible range of -0.048 to 0.3915,while ArcMap included a range of -31.68 to 45.17. The mean and std in ArcMap are 0.1718 and 0.0887 leading me to believe that these extreme values are a few pixels only. How do I clip these extra pixels of in ArcMap?
