The coverage map shows the extents of the National Transformation Grid File released on the 13/09/2001. The new grid aids the transformation between AGD and GDA geographical [AGD66 - GDA94] and UTM grid [AMG66 - MGA94] coordinates across Australia. The image below shows the extents to which the new grid file can be used.
