This dumb RGB image is created from several publically available AEM surveys. Conductivity depth slices from each survey, usually between 0–300 m below surface, were combined and given a colour stretch. These were then stitched together into the dumb image. Pixels of red and yellow indicate higher conductivity.

Dumb RGB image. Based on ‘spectrum-full bright’ colour stretch. This is a blue–yellow–red stretch, indicating conductivity values, ranging from lower to higher, respectively. Being an amalgamation of different surveys and AEM systems, no absolute conductivity values are given.
