Abstract
<div>Tasseled Cap percentiles provide an annual summary of how the environment has varied through a year. The Tasseled Cap percentiles provide the upper, lower and middle conditions as described by the 90th, 10th and 50th percentiles respectively, of greenness, wetness and brightness across the landscape.</div><div><br></div><div>These percentiles are intended for use as inputs into classification algorithms to identify such environmental features as wetlands and groundwater dependent ecosystems, and characterise salt flats, clay pans, salt lakes and coastal land forms.</div><div><br></div>

Purpose
The Tasseled Cap (Kauth–Thomas) transformation takes satellite imagery and shows the degree of greenness, wetness and brightness across the observed area. These indexes help users understand the combinations of vegetation, water and bare areas respectively. As such the Tasseled Cap is a useful input into environmental analyses, especially where there are mixtures of all three features in the landscape, such as in wetlands. This product offers three percentiles per Tasseled Cap index per year. The percentiles are 10th, 50th, and 90th; the Tasseled Cap indexes are ‘greeness’, ‘wetness’, and ‘brightness’; and the years are from 1987 to now. It includes cloud and shadow buffering with a size of 6 pixels. This buffering is applied to Landsat 5, Landsat 7, Landsat 8, and Landsat 9 data. Please note, validation data was not available to verify the accuracy/quality of this product. It is provided 'as is' and not undergone quality control processes.
