I am writing a program that convert TM-2 degree to lat/lon on Android, but I can't find formula for that. I do find some example on internet, but most of them are convert with open source library, that I can't use on Android platform. I also find a java class that do convert from UTM to lat lon, but it seems no suitable for TM 2 degreen coordinate system. So my question is: how do I convert TM 2 degree coordinate to lat/lon? Where can I find formula?

    What is a TM-2 degree? Probably why you can't find anything by googling, maybe you're calling it something different? – Kekoa Jul 07 '09 at 02:24
  • Does TM = transverse mercator? If so, then you're asking how to convert UTM coordinates to Lat/Long? – Derek Swingley Jul 07 '09 at 03:28

If you have access to the open source libraries, and they are open source, then you can easily download the source code and take a look at the algorithm necessary for the conversion. This is really a platform independent question, it doesn't matter much that you're on Android, once you know the algorithm you could implement it with any language you like.

Also, I don't think the official name is TM-2, I can't find references to it as a Geodetic System or as a Geographic Coordinate System.
