In this paper they are using the assertion based on McFeeters paper that, NDWI values greater than zero are identified as water surfaces. But, what if I have NDWI values in the range of negative values only, added that it contains water bodies. I have Landsat image of Jaipur for 15th May, and calculated NDWI using Green & NIR band. I'm getting the NDWI value ranging from -0.268 to -0.134. What should I interpret from this result then?

Gajanan Kothawade visualize your satellite imagery in FCC. Check if there are any waterbodies visually. Jaipur + Summer could mean relatively less water bodies. Right?
