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.

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.

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.

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.

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.

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.

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 the first vertical derivative (1VD) of total magnetic intensity reduced to the pole (TMI RTP) which has been upward continued by 500m. 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). Upward continuation artificially increases the elevation which removes the influence of high frequency signals caused by near surface geology. The 1VD filter shows the vertical rate of change in the Earth's total magnetic field and enhances boundaries and structural detail of shallow sources. 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.

Greyscale image of the tilt-angle filter (Tilt) 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 Tilt filter produces a positive maximum over the centre of a magnetic source and is zero near the edge of the source, and is useful for tracing geological structure below variable depths of cover. 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.
