map. This would give us a rough idea of the distance. For a challenge, try this: 1. Convert the latitude/longitude data from degrees decimal to degrees, minutes and seconds.
2. Re-write the new readings to this format [00:00:00N] for Degrees:minutes:secondsLatitude. Do this for Longitude [00:00:00W], too.
