Abstract
A method and systems for loading and tracking maps on a moving vehicle. One method includes obtaining a geographic location of a system on a vehicle, obtaining a boundary corresponding to a contiguous geographical boundary area around the geographic location of the system, loading map data comprising a plurality of map data tiles each including a portion of the geographical boundary area, the plurality of map data tiles including a center tile having a point corresponding to the system location and surrounding map data tiles. The method further includes obtaining an updated system location, and if the updated geographic location is outside of the boundary area, obtaining an updated boundary centered on the updated geographic location and loading map data based on the updated boundary such that the resulting loaded map data includes a center tile and map data tiles surrounding the center tile that intersect the geographical boundary area.
