#gis How to calculate Normalize Difference Water Index in ArcGIS

Normalize Difference Water Index (NDWI) is use for the water bodies analysis. The index uses Green and Near infra-red bands of remote sensing images. Higher NDWI values indicate sufficient moisture, while a low value indicates water stress.

NDWI Formula,

NDWI= (Green-NIR) / (Green+NIR)
For Landsat 8, NDWI= (Band 3-Band 5) / (Band 3+ Band 5)
