I already search SE already if the question has been raised before but I can't find one so I'll ask here anyway. I'm creating a small application which involve geofencing my GPS device doesn't have a geofencing capability on it's own which I hope it has this feature for accuracy and ease of programming.
I have no choice to do it on the server level, my question is since my device is sending NMEA/GPRMC on a two minute interval is there an algorithm that we can use to detect the exact timing the vehicle leave or enter the geofence?
my current code can detect the vehicle inside/outside the geofence area no matter what type of polygon it's just the timing issue I can't solve.
Thanks in advance
