I'm creating an android version of a PC program (I've contacted the company who owns the PC program, so it's legal). The program is in the core a GPS, but is used to navigate pre-defined routes for heavyweight transports, because they are not allowed to pass some bridges. However, that isn't very important for my problem. The program reads the coordinates from text files, so my app needs to do that too, but those coordinates are not in the range -180 to 180 and -90 to 90. So I can't really understand them. For example, one coordinate has these values:
I need to convert these coordinates to WGS84 coordinates (lon and lat) in order to be able to use them for what I want.
