I suggest you used alter the coordinate system (projections) in MapXtreme as
it will be rather simple as oppose to the algorithm; which you can find on
the www.auslig.gov.au site. You will even find the algorithm translated in
semi program code; as they supply an EXCEL spreadsheet which will do the
translation.

Subject: MI-L MI - Projection Algorithmn
Hello all,
This is more for Australian MapInfo people.
I would like to acquire an algorithm so that I can build a function that
will enable me to convert
a single Lat - Long WGS 84 co-ordinate into an AMG (Australian Map Grid)
co-ordinate.
For example if I feed in a lat or a long co-ordinate I would like the
function to spit out the equivalent
AMG X or Y coordinate.
I'm not after conversion programs, but an actual algorithm, which I then can
put into a MapXtreme program,
that when requested by the user will give the AMG co-ordinate of the feature
they have selected or moused over.
I know I can alter the Coordinate system in a MapXtreme program but that
will be an overkill and an unnessary
overhead on the system to convert between Lat/Long and AMG on the fly
whenever a map is redrawn.
Thanks for any help
Roger
