GSWA East Canning 3 TMI Grid Geodetic

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 GSWA East Canning 3 TMI Grid Geodetic has a cell size of 0.00083 degrees (approximately 89m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 122578 line-kilometres of data at a line spacing between 200m and 400m, and 50m terrain clearance.

Statement

This GSWA East Canning 3 TMI Grid Geodetic is an airborne-derived Total Magnetic Intensity (TMI) grid for the Stansmore, WA, 2010 (East Canning 3) survey. The survey was acquired under the project No. 1227 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 89m). The units are in nanoTesla (or nT). A total of 122578 line-kilometres of data at a line spacing between 200m and 400m, and 50m 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.
