Great effort
Good job
The video was Great. But i have a doubt. i am getting different NDVI values for the same sentinal-2 image when calculated in QGIS using raster calculator and ERDAS Imagine. please clarify. Thanks in advance.
radiometric correction needed in this?
Sir I have 4 scenes, how should I compute for the NDVI for the whole study area? Thank you
Sorry does L2A images are sufficient to obtain good ndvi values? I see some people do so king of cloud masking for pixels that are cloudy. Do L2A images need such treatment? thanx

Yan Bensamoun The sentinel-2 Level 2A is a BOA reflectance of Level-1C TOA product, so it is corrected for the atmospheric disturbance.

Where is the link for learning how to download the data from COAH?
