Radiometric - Ternary Ratio/Total Count Drape - 2005 map

dataset: victoria_2005jan25_mrg_radtc_50m_vg94.ecw
This ternary radioelement image of potassium–thorium–uranium data is a red-green-blue (RGB) composite using a histogram-equalised colour-stretch on each of the three channels, draped over a sun illuminated radioelement total count (TC) intensity surface. The red, green and blue channels represent potassium (K), thorium (Th) and uranium (U) respectively, for K values in percent (%), Th values in parts per million (ppm) and U values in ppm. Mixed compositions are indicated by the ratio of the corresponding additive primary colours. For example yellow represents the presence of both K and Th, magenta the presence of K and U, and aqua the presence of Th and U. Black indicates low concentrations and white represents high concentrations of all three radioelements. Colour: 2005 Ternary Ratio Victorian state-wide 50x50m grid. Intensity: 2005 total count Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.
