How could I get the lat,long of an object by knowing its xy values(in meters) from my vehicle (assuming it is(0,0) the center)? For example my vehicle lat,long is 30,31 but it's xy values are always going to be (0,0). The object xy for example is (1.3,1.2) from the vehicle (in meters). How could I then change it to a lat and long?
A similar problem is described here, maybe it helps you to get started, though it presumes a given direction and distance:
