Total Magnetic Intensity colour composite image 2015 The image was created from the Total Magnetic Intensity Grid 2015 - sixth edition. This image has a cell size of ~3 seconds of arc (approximately 80 m) and has been image enhanced for optimal display in Hue-Saturation-Intensity (HSI). This image only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the fifth edition was released in 2010 data from 41 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. It is estimated that 31 500 000 line-kilometres of survey data were acquired to produce the grid data, 4 500 000 line-kilometres more than for the previous edition.

Digital image data in BIL format of pixel image maps for three areas of North Queensland: 1. Cooktown/Mossman; 2. Atherton; and 3. Gilberton 1:250 000 sheet areas. Each area consists of three maps: 1. Total Magnetic Intensity, reduced to pole, colour; 2. First Vertical Derivative greyscale; 3. Gamma-ray spectrometric colour composite.

Gravity Anomaly image 2009 (Colour Composite Image) This image is made from a grid that represents gravity anomalies of the Australian region. The grid combines accurate onshore gravity measurements, with satellite data over the offshore region. The cell values represent simple Bouguer anomalies at a density of 2.67 tonnes per cubic metre onshore and free-air anomalies offshore. The grid cell size is 0.5 minutes of arc, which is equivalent to approximately 800 metres.
