Hi all, I am trying to display the coordinates of the mouse pointer in an application (not MapInfo). The map data is currently in AMG a Universal Transverse Mercator projection), and the sidplay is quite easy using trigonometry. Unfortunately the users don't know about AMG coordinates so want the display in Lat/ Long. I am trying to write some code to convert the coordinates to WGS84 lat/ longs at run-time. The required accuracy for display only needs to be within a few meters.
I have found a conversion spreadsheet based on the Redfearn's formulae from the Auslig site that is quite complex (40 or so stages), that I will attempt to simplify to put it into code if it is the only way, but thought I would ask if anyone has already done this? This also may be a bit complex for real-time conversion. The Auslig spreadsheet is for GDA, but as I understand it, I just have to use a different ellipsoid and flattening factor. Am quite happy to provide the code snippet to anyone once I have completed it.
