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. The system identifies 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 cache storage. The pre-fetch map data tiles are identified using a variable map tile radius, which when extended from the points of interest defines the map tiles that qualify as pre-fetch map data tiles. The tile radius can be fixed or dynamically adjusted and changes across different map zoom levels.
