This article presents a procedure for image enhancement applied to the aeromagnetic component of the Gawler Craton Airborne Survey (GCAS). The aim is to create enhanced images of total magnetic intensity value that capture the broad spectrum of magnetic amplitudes and wavelengths recorded by GCAS. The hue, saturation and value (HSV) colour model whose properties allow both long- and short-wavelength information to be clearly displayed in a single image is applied. The result reflects colour as it is perceived under natural light. However, any particular enhancement represents an inherent trade-off. Therefore, the images presented here are intended to complement existing derivative products. The images will serve a new geological interpretation of the Gawler Craton under the South Australian Discovery Mapping project.
