    Calculating Waypoints.

    I've been using the GPRMC data, from my gps unit.

    When I want to record a waypoint, I save the Lat/Lon data from the GPRMC string.
    But you do not always get an exact match, to the Lat/Lon the next time you
    pass the same location. (GPS is not that accurate)

    What is the best way to calculate a bigger waypoint window.
    Is there a standard way to do this?

    I have some code working but it's not 100% accurate.

    Any help!
