Short Description

The Normalised Difference Water Index (NDWI) (McFeeters, 1996) is calculated for each observation, and a pixel based median NDWI composite derived for each percentile interval of the cell’s OTR. The pixel-based standard deviation of NDWI values within each percentile interval is also recorded for use in the Confidence Layer.
