Incorrect band information in the Normalized Difference Snow Index (NDSI) mentioned in the ArcGIS Pro web documentation and ArcGIS Pro Application NDSI function's description.
The information about the NDSI function in ArcGIS Pro provided in the web help where it's mentioned as:NDSI = (Green - NIR) / (Green + NIR)This information should be changed to:NDSI = (Green - SWIR) / (Green + SWIR)The documentation also states that the function is designed for 'MODIS', which needs to be changed to MODIS & LANDSAT TM.
