This is a multi-date water mask image. It represents the number of images in the time series classified as water using the Landsat based water index. This index was developed using Canonical Variates Analysis (CVA) of visually identified water and non-water signatures in radiometrically calibrated Queensland wide Landsat imagery. The index is a linear combination of bands, Log transformations of bands and interactive band terms.; ; Unsigned 8 bit; Band 1 = number of dates classified as water; ; Reference:; Danaher, TJ & Collett, L (2006).
