NSW Airborne Gravity
This is a preliminary low-resolution, pseudocolour image of airborne acquired Bouguer gravity with a histogram-equalised colour stretch. Cooler colours indicate lower Bouguer gravity values and warmer colours represent higher values. Bouguer gravity compensates for variations in latitude, 'free-air' elevation and Bouguer correction (assuming a crustal density of 2.67 T/m³). This image shows airborne gravity data from a survey that is ongoing. The Department of Customer Service has contracted two experienced specialist companies to fly the airborne survey. Final data will be available in 2024 at a higher resolution. Preliminary data should not be used in geological interpretations.

- Statement
- The preliminary Bouguer gravity was provided by the Department of Customer Services to the Geological Survey of NSW to publicly show survey progress. Bouguer gravity reduction was undertaken by the contractors hired by the Department of Customer Service. The resolution of the data has been downgraded to prevent interpretation of small structures that may not be apparent in the final data. The units for the data are μms⁻².
