Raster Calculation (Pre-Defined Indexes)

See Formulas

NDVI = (NIR-RED)/(NIR+RED) ​ NDWI = (G-NIR)/(G+NIR) ​ NBR = (NIR-SWIR)/(NIR+SWIR) ​ NPCRI = (Red-Blue)/(Red+Blue) ​ NDSI =(Green-SWIR) / (Green+SWIR) ​ ​ NDGI = (NIR-Green)/(NIR+Green) ​ NDMI = (NIR – SWIR) / (NIR+SWIR) ​ AVI = [NIR * (1-Red) * (NIR-Red)] 1/3 ​ BSI = ((Red+SWIR) – (NIR+Blue)) / ((Red+SWIR) + (NIR+Blue)) ​ SI = [(1-Red)*(1-Green)*(1-Blue)]1/3

  • Select Raster Calculation to perform
  • specifies the bit depth for the output band(s) (one for each FORMULA parameter). Valid values are 8, 16, or 32. If you don't specify this then you will get 32-bit floating point values if the output is a single band grid and 8-bit per band for imagery output.
  • specifies how many bits to use for each band of data. If you don't specify a value for this the highest bit depth of any of the input data layers will be used.
