Cobar P5009 EXT 1 total magnetic grid
Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Cobar P5009 EXT 1 total magnetic grid has a cell size of 0.00039074 degrees (approximately 40m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance.

- Purpose
-
This data set forms part of the NSW and national airborne magnetic and radiometric mosaic that is continually updated with higher resolution datasets. When integrated with other geological, geochemical, geophysical or technical datasets, it provides pre-competitive insight into the mineral, groundwater, energy, soil and other resource potential of the continental land mass. Subject to the quality control, equipment tolerances and inherent limitations on the measurements themselves, it may also be employed for other geophysical and scientific investigations into the earth.

- Statement
-
This Cobar P5009 EXT 1 total magnetic grid is an airborne-derived Total Magnetic Intensity (TMI) grid for the Cobar Magnetic and Radiometric Survey, 2021 survey. The survey was acquired under the project No. 5009 for the geological survey of NSW. The grid has a cell size of 0.00039074 degrees (approximately 40m). The units are in nanoTesla (or nT). A total of 53617 line-kilometres of data at a line spacing of 200m and 60m terrain clearance were acquired to produce this grid. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014). This Index is also available online at http://pid.geoscience.gov.au/dataset/79134.
