Creating NDVI map without cloud cover

Hey guys,


i´m trying to create an NDVI map from Landsat 8 OLI images by using raster calculator witth the NDVI formula (NIR-Red / NIR+Red).

So far it worked out pretty good, but I have a few clouds in my satelllite data which I´m trying to mask out.

I already used the QA band for cloud and cloud shadow masking, but I don´t know how to apply it on my calculations.

I tried to put the cloud values to zero, but then I get NDVI values which ranges from -110 to 32. So I think this way doesn´t work properly.


I would be grateful on suggestions on how to handle cloud cover in NDVI calculations.


Thank you in advance!
