Merged Magnetic, Radiometric and Elevation Grids for the NTGS Tanami Region (Northern Territory)  


Authors / CoAuthors

Goodwin, J.A.

Abstract

<p>Various gridded images were produced from the NTGS Tanami Region Airborne Magnetic and Radiometric Survey dataset and simultaneously merged into a single grid file. The final grid retains all of the information from the input data and is levelled to the national map compilations produced by Geoscience Australia. <p>The following merged grids are available in this download: <p>• Laser-derived digital elevation model grids (m). Height relative to the Australian Height Datum. <p>• Radar-derived digital elevation model grids (m). Height relative to the Australian Height Datum. <p>• Total magnetic intensity grid (nT). <p>• Total magnetic intensity grid with variable reduction to the pole applied (nT). <p>• Total magnetic intensity grid with variable reduction to the pole and first vertical derivative applied (nT/m). <p>• NASVD-filtered potassium concentration grid (%). <p>• NASVD-filtered thorium concentration grid (ppm). <p>• NASVD-filtered uranium concentration grid (ppm).

Lineage

Original point-located data is available from: https://geoscience.nt.gov.au/gemis/ntgsjspui/handle/1/89442 Grids were generated from the NTGS dataset using Intrepid v5.6.4 and merged using a process developed within Geoscience Australia referred to as Grid Merge (Minty et al., 2003). The Grid Merge process is implemented in Intrepid software's Grid Merge Tool.
