I have Landsat level-2 NDVI tiles I am using in ArcMap 10.4.1.; however, the level-2 NDVI data in ArcMap ranges from -5,189 to +20,000.
The spectral image product guide (which I've linked) says that the valid range for level-2 NDVI is -10,000 to 10,000 with a scale factor of 0.0001, which makes sense. The saturate value is 20,000. I don't understand what the saturate value is and why the upper bound of the level-2 NDVI layer is 20,000.
I understand that to get NDVI values I need to multiply the level-2 layer by 0.0001. However, I'm unsure what to do about the saturate values since they are above the valid range. I'm guessing that the saturate value indicates pixels that are unusable; in other words, once I multiply the level-2 layer by 0.0001, I would then throw out all pixels >1. Is this correct?
