I 'm developing on J2ME.
Reading coordinates from external gps.
Evaluating the GPGGA string.
The latitude value is represented in DDMM.MMMM format
and longitude value in DDD.MM.MMMM format.
To convert on DD.DDDD value, I do in this way:
DD + (mm.mmmm / 60)
DDD + (mm.mmmm/60)
in this way, the mapped position is moved from the real position of 7~9 meters.
I think there's an approssimation error on the division, anyone can suggest me a better kind of conversion?
