I have rescaled my bands using the scale factor in raster calculator: band(0.0000275)- 0.2
The rescaled band ranges from -0.1 to 1.1 even though that shouldn't be happening?
Further, if I just go ahead with the rescaled band, the NDVI values range from -8554 to 5080. The NDVI range lies within -1 to 1 if I simply use the original bands without the rescaling. How do I fix this and why this might be happening?
I am working in ArcGIS.
