Commonwealth and State and Territory governments have devoted considerable resources to acquiring these data sets and making them available to encourage exploration. Geoscience Australia's geophysical databases contain data acquired by governments, and this report summarises coverages over Australia of these data. On the occasion of the centenary issue of Preview, it is worth reflecting on the advances in the coverage of publicly available magnetic, gamma-ray and gravity data over Australia since the first edition of Preview in February 1986. Since then the areas and resolution of coverages have increased dramatically. Quality of the data through better acquisition and processing techniques has also improved, and new types of data sets added to the explorers' supplies. {"type": "Polygon", "coordinates": [[[110.0, -44.0], [156.0, -44.0], [156.0, -9.0], [110.0, -9.0], [110.0, -44.0]]]} 110.0 156.0 -44.0 -9.0 AU Article Earth Sciences External Publication Published_External gamma spectroscopy geophysics gravity magnetics Download the file (pdf) documentDigital Download the file (pdf) PDF Unnamed resource documentDigital HTML
