Player Positions

Hello,

I am trying to get a GPS or Longitude/Latitude systems going with this engine for player positioning. I would like to ask those of you who are familiar with the engine, what you believe to be the best way of doing this. I am not asking for code, just suggestions on what to look into and what I should maybe stay away from. I am new to this engine and I am trying to learn as much about it as possible. So far the resource section has been great.

Thanks,

Joe
