Full description

Several products were produced from the Total Magnetic Intensity (TMI) Grid of Australia 2019, seventh edition (eCat ID 131505). The grid was found to include 3 extreme, high-amplitude cultural data spikes from current and historical aluminium smelters in Victoria and Tasmania. Also, 3 data spikes of unknown origin were located in the Hunter region of NSW. These 6 data spikes were removed from the gridded data. The following products were produced from the grid with the data spikes removed:

1.    Total Magnetic Intensity (TMI) edited grid (.ers)
2.    Variable Reduction to Pole (VRTP) grid (.ers)
3.    First Vertical Derivative (1VD) grid (.ers)
4.    Half Vertical Derivative (05VD) grid (.ers)
5.    Pseudo-Gravity (PGrav) grid (.ers)
6.    Pseudo-Gravity, Total Horizontal Derivative (THD) grid (.ers)
7.    Susceptibility (Sus) grid (.ers)
8.    Variable Vertical Gradient (VBzz) grid (.ers)
9.    Analytic Signal (AS; Total Gradient) grid (.ers)
10.    Tilt Angle (Tilt; Phase Map) grid (.ers)
11.    Tilt Angle (Tilt; Phase Map), Total Horizontal Derivative (THD) grid (.ers)
12.    Upward Continuation (UC) Residual (Res) Filters (0 to 100 km; 12 grids)
13.    Mutliscale Edge Detection Polygons (for each MGA zone; .shp)
14.    Analytic Signal Phase Polygons (.shp)
15.    GeoTiff Images (of all grids; .tif)
