This image has a cell size of ~3 seconds of arc (approximately 80 m) and has been image enhanced for optimal display in Hue-Saturation-Intensity (HSI). This image only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the fifth edition was released in 2010 data from 41 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. It is estimated that 31 500 000 line-kilometres of survey data were acquired to produce the grid data, 4 500 000 line-kilometres more than for the previous edition. {"type": "Polygon", "coordinates": [[[112.503782, -43.922731], [154.662932, -43.922731], [154.662932, -9.026912], [112.503782, -9.026912], [112.503782, -43.922731]]]} 112.503782 154.662932 -43.922731 -9.026912 AU Airborne Digital Data Geophysical National Coverage HSI Magnetism and Palaeomagnetism NCI Published_External TMI magnetics pixel images Download Magnetic Map of Australia 6th Edition 2015 (pdf – 21.5MB) documentDigital Download Magnetic Map of Australia 6th Edition 2015 (pdf – 21.5MB) PDF Web Map Service documentDigital Link to Web Map Service WMS Unnamed resource documentDigital HTML
