Sentinel-2 NDVI Processing

When I make a call to get Sentinel-2 imagery with a specific BBOX and do NDVI processing on the imagery:

  1. Which is done first, the BBOX clipping and then processing or processing on entire scene and then clipped to BBOX
  2. If the clipping is done after processing would the return image be less accurate if the processing was done after clipping to BBOX


We only process the relevant pixels, never the whole scene. So clipping is first.
