Mapping flood plumes from water colour

Triangular colour plot showing the characteristic colour signatures of the GBR wet season waters in the Red-Green-Blue (or true colour) space. A remote sensing method has been developed to map these characteristic coastal water types in the GBR using a supervised classification of MODIS true colour data.
