Magnetic anomaly grid (80m) of Western Australia (2011 - version 2)

Date released: 2 September 2010

This merged magnetic anomaly grid is generated from Federal and State government data sets acquired with a line spacing of 500 metres or less and selected open file data sets. The "Geoscience Australia magnetic grid of Australia V5 2010" has been used as a base reference grid and is also used to complete the background areas where closer spaced data are not available. The final grid has a cell size of approximately 80 metres (0.000833333 degrees). The grid file is approximately 2GB size and, at present, is only available on DVD ($99) or external hard drive ($132); it is not available by download from the Geoscience Australia GADDS facility.  A data request may be submitted via the online request form at http://www.dmp.wa.gov.au/magix.  The recommended reference for this grid is "Geological Survey of Western Australia, 2011 magnetic merged grid of Western Australia".

A pseudocolour image in ecw format has been compiled for download at no charge.

The image was generated from a colour palette (red high. blue low) using histogram equalisation. To emphasize the expression of high-frequency anomalies, an artificial illumination was applied from the northeast. The data have been compressed 5:1 using enhanced compressed wavelet technology
