Total magnetic intensity (80m) 1VD of WA v1, 2020 (DMIRS-068)

First Vertical Derivative (1VD) of TMI - The data are displayed as a greyscale image with histogram equalization. This merged magnetic anomaly data from onshore and offshore WA is generated from Federal and State government data sets acquired with a line spacing of 500 metres or less and over 1600 open file Company data sets at various line spacing's. The Geoscience Australia magnetic grid of Australia V6 2015 (Nakamura, 2015) has been used as a base reference grid and is also used to complete the background areas where closer spaced data are not available.
