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 6 total magnetic intensity 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. {"type": "Polygon", "coordinates": [[[145.1, -33.1], [147.1, -33.1], [147.1, -31.1], [145.1, -31.1], [145.1, -33.1]]]} 145.1 147.1 -33.1 -31.1 Australia EARTH SCIENCES Earth sciences GADDS2.0 NCI NSW Published_External TMI airborne digital data geophysical survey geophysics grid mag magnetics magnetism palaeomagnetism raster survey 5009 total magnetic intensity File available for download in various formats from the GADDS2 portal documentDigital The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
