  • This is a pseudocolour image of Total Magnetic Intensity Reduced to the Pole (TMI RTP) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher magnetic intensity values, in nanoTeslas (nT). A single RTP correction, calculated for the centre of the state-wide grid, has been applied to the whole grid. Colour: TMI (RTP) 2011 Victorian state-wide 50x50m grid. Intensity: 2011 TMI (RTP) Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.

  • This is a pseudocolour image of uranium (U) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher U parts per million (ppm) values. Colour: 2005 uranium Victorian state-wide 50x50m grid. Intensity: 2005 uranium Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.

  • 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. 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. e.g. 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.

  • This is a pseudocolour image of Total Magnetic Intensity (TMI) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher magnetic intensity values, in nanoTeslas (nT). Colour: TMI 2011 Victorian state-wide 50x50m grid. Intensity: 2011 TMI Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.

  • This is a pseudocolour image of Total Magnetic Intensity Reduced to the Pole (TMI RTP) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated First Vertical Derivative of Total Magnetic Intensity Reduced to the Pole (1VD TMI RTP) intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher magnetic intensity values, in nanoTeslas (nT). A single RTP correction, calculated for the centre of the state-wide grid, has been applied to the whole grid. Colour: 2011 TMI (RTP) Victorian state-wide 50x50m grid. Intensity: 1VD TMI (RTP) 2011 Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.

  • This is a pseudocolour image of the radioelement total count (TC) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Cooler’ colours indicate lower values and ‘warmer’ colours represent increasingly higher TC in nanoGrays per hour (nGy/h) values. Colour: 2005 total count 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.

  • This is a greyscale image of First Vertical Derivative of Total Magnetic Intensity Reduced to the Pole (1VD TMI RTP) Victorian state-wide grid data generated using a histogram-equalised colour-stretch draped over a sun illuminated intensity surface. ‘Darker’ shades indicate lower values and ‘lighter’ shades represent increasingly higher values of the vertical rate of change of the total magnetic field (TMI RTP), in nanoTeslas per metre (nT/m). A single RTP correction, calculated for the centre of the state-wide grid, has been applied to the whole grid. Colour: 2011 1VD TMI (RTP) Victorian state-wide 50x50m grid. Intensity: 1VD TMI (RTP) 2011 Victorian state-wide 50x50m grid. Sun illumination was set at 45 degrees azimuth and 60 degrees altitude.
