Images produced by different Water Indexes using Landsat 8 OLI. Contrast enhancement was stretched to one standard deviation both sides. (a) NDWI of McFeeters [13], (b) NDWI of Rogers and Kearney [14], (c) MNDWI of Xu [15], (d) AWEInsh of Feyisa et al. [16], (e) AWEIsh of Feyisa et al. [16], (f) NIR band. White to black for all multi-band water indexes (a to e) is low to high index values as pixels with values greater than their respective threshold values are water bodies. White to black for NIR band (f) is high to low index values as pixels of NIR band with values less than its threshold value are water bodies
