The data collected 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 radiometric uranium grid has a cell size of 0.00042 degrees (approximately 42m) and shows uranium element concentration of the St Arnaud Infill merge, 1990 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1990 by the VIC Government, and consisted of 18970 line-kilometres of data at a line spacing between 200m and 400m, and 100m terrain clearance. {"type": "Polygon", "coordinates": [[[142.6016, -37.2776], [144.0666, -37.2776], [144.0666, -36.4724], [142.6016, -36.4724], [142.6016, -37.2776]]]} 142.6016 144.0666 -37.2776 -36.4724 Australia EARTH SCIENCES Earth sciences GADDS2.0 NASVD NCI Published_External U VIC airborne digital data gamma-ray geophysical survey geophysics grid rad radiometrics raster spectrometry survey 1345 uranium 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.
