Abstract
A system includes a processor configured to receive vehicle speed and heading. The processor is also configured to determine a local data set having coordinates reachable by a vehicle traveling at a projected speed based on the received speed and heading within a predetermined amount of time. The processor is further configured to define a geo-fence at a distance from a local data set perimeter such that a vehicle reaching the geo-fence at the received speed will have time to download new local data before reaching the local data set perimeter and send the geo-fence definition and coordinate data within the local data set to the vehicle.
