Abstract
A pre-fetching map data system and method identifies a subset of map data to corresponding to one or more points of interest to be displayed on the map. The map data is stored on a remote map database and in the form of map data tiles bearing version numbers. The pre-fetching map data system identifying those map data tiles that correspond to the subset of map data corresponding to the one or more points of interest, where the identified pre-fetch map data tiles are sent from the remote database to a client device for storing the pre-fetch map data tiles. During pre-fetching the version number of the received map data tiles is examined to determine if a version update for additional map data tiles should be scheduled and executed to update out of date map data on the client device.
