Full description

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.

The following merged grids are available in this download:

•    Laser-derived digital elevation model grids (m). Height relative to the Australian Height Datum.

•    Radar-derived digital elevation model grids (m). Height relative to the Australian Height Datum.

•    Total magnetic intensity grid (nT).

•    Total magnetic intensity grid with variable reduction to the pole applied (nT).

•    Total magnetic intensity grid with variable reduction to the pole and first vertical derivative applied (nT/m).

•    NASVD-filtered potassium concentration grid (%).

•    NASVD-filtered thorium concentration grid (ppm).

•    NASVD-filtered uranium concentration grid (ppm).

Lineage

Maintenance and Update Frequency: asNeeded
Statement: 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.
