All airborne geophysics has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

Gravity gradiometry data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

This vector file contains the location of reprocessed surveys and their acquisition parameters. These reprocessed surveys are from airborne geophysical surveys that have been submitted to the NSW government by exploration and mining companies. They have been publicly released under the NSW Mining Act 1992.

Magnetic and radiometric data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

AEM data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of AEMsurveys and acquisition parameters.

Ground surveyed gravity data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

EM-IP-MT survey data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

Geophysics survey data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters. These surveys use uncommon techniques.

Greyscale image of second vertical derivative (2VD) of total magnetic intensity reduced to the pole (TMI RTP). Darker tones indicate lower values and lighter tones represent higher values. Reduction to the pole filters magnetic anomalies to appear as if the Earth's magnetic field were locally vertical, as at the magnetic pole (assuming all magnetic sources are inductively magnetised). The 2VD filter shows the vertical rate of change in the first vertical derivative (1VD) of the Earth's total magnetic field and enhances boundaries and structural detail of shallow sources further than 1VD. The 2VD filter enhances magnetic textures in the image, however, it also amplifies non-geological noise. Variations in the magnetic field are caused by lithological factors, principally magnetite (and/or pyrrhotite) content. This Statewide image was generated by merging many individual airborne magnetic surveys.
