The Australian Map Grid

The Australian Map Grid (AMG) is a Universal Transverse Mercator (UTM) projection. The continent is divided up into zones which have a width of six degrees of longitude. Here is a map showing the AMG zones.

Technical Information for this Spatial Transformation

AMG to Geographicals Transformation
Geographicals to AMG Transformation

Script:

The spatial data transformation is performed by a Perl script which has parameters passed to it via the forms interface.

Mathematics:

The transformation algorithm makes use of Redfearn's rigorous formulae as published in the National Mapping Council Special Publication 10 - The Australian Geodetic Datum Technical Manual, 1986. This transformation utilizes the Australian Geodetic Datum 1966.

Spatial Accuracy:

Depending upon the precision of the entered coordinates, this transformation will compute results to the nearest 4mm (nominal) on the ground.

Future Enhancements:

To cater for Geographicals in both Decimal Degrees (DD) and also Degrees, Minutes and Seconds (DMS). Also to possibly cater for transformations based on other spheroids.
