Solve Maps

These data products aim to provide a geologically meaningful and visually appealing representation of the geoscientific data compilations provided by Geoscience Australia. Several products are available, with different focuses and interpretable information.

Gravity and Magnetic data

Both of the following datasets combine information from the gravity and magnetic potential field data over Australia.

A vertical derivative (power = 0.5) was applied to each of the Complete Bouguer Anomaly of the gravity data and the Reduced to Pole total field data. This attenuates the long-wavelength information while highlighting localised changes in the potential field. An isoluminant colour map was then applied so that a uniform perceptual contrast is observed over their whole range (Kovesi, 2015). This means that there are no perceived differences in colour intensity due to the colour map.

Gravity with magnetic-shadow

This data is coloured by gravity with shading from the magnetic data.

A greyscale version of the magnetic data is then multiplied by the isoluminant gravity. This has the effect of changing the image intensity; lightorange represents coincident gravity and mag highs while dark-orange represents gravity high with mag low, where orange is high gravity.

A greyscale, anisotropic hillshade of the magnetic data is then multiplied by the product to highlight short-wavelength changes in the magnetic field data.

Magnetics with gravity-shadow

This data is coloured by magnetics with shading from the gravity data.

A greyscale version of the gravity data is then multiplied by the isoluminant magnetics. This has the effect of changing the image intensity; lightorange represents coincident mag and gravity highs while dark-orange represents mag high with gravity low, where orange is high magnetics.

A greyscale, anisotropic hillshade of the gravity data is then multiplied by the product to highlight short-wavelength changes in the gravity field data.

Radiometric data

This map portrays the relative distribution of the surficial abundance of potassium, thorium and uranium across the Australian continent. The colour of the map is a ternary image, where the red, green and blue amounts correspond to the potassium, thorium and uranium, respectively.

An omni-directional sun-angle shading of the topography (SRTM) and of the radiometric dose was overlain on the ternary image to highlight topographic effects and to compliment the relative distribution with a measure of the total radiometric response.
