Abstract

These images are derived from the January 2002 edition of the "Magnetic Anomaly Grid of the Australian Region" (GEOCAT Record : 38820). That grid is the first integrated onshore/offshore magnetic anomaly grid for the complete Australian margin extending across 8S - 52S, 106E - 172E. The grid cell size is 0.01 degree (approx. 1 km). Earlier releases were restricted to portions of NW and SW Australia.

Lineage

Using an ER Mapper algorithm associated with the "Magnetic Anomaly Grid of the Australian Region" (GEOMET Record : 4321) a colour geo-referenced TIF with a cell size of 0.01 degrees was generated using the elevation palette and manipulated so as to appear to be illuminated from the north-east. A compression ratio of 27 was used, utilising ER Mapper's ECW compression algorithm, to compress the TIF image to an adequate size for provision over the Internet. The geo-referenced TIF was then reprojected to Lambert Conformal Conic projection, with a cell size of approximately 1000 metres using ArcInfo. Georeferenced TIF images and ECW compressed images were then generated for this projection in the same process outlined above.
