Murray Global Intertidal Change QA Pixel Count (UQ/murray/Intertidal/v1_1/qa_pixel_count)
Version v1.1
The Murray Global Intertidal Change Dataset contains global maps of tidal flat
ecosystems produced via a supervised classification of 707,528 Landsat
Archive images. Each pixel was classified into tidal flat, permanent water
or other with reference to a globally distributed set of training data.
The classification was implemented along the entire global coastline
between 60° North and 60° South from 1 January 1984 to 31 December 2016.
The image collection consists consists of a time-series of 11 global maps
of tidal flats at 30m pixel resolution for set time-periods (1984−1986;
1987−1989; 1990−1992; 1993−1995; 1996−1998; 1999−2001; 2002−2004;
2005−2007; 2008−2010; 2011−2013; 2014−2016)
The number of Landsat images used to develop the Landsat covariate layers
in each time step of the tidal flat classification. Each image in the image
collection refers to a single time step.
