Abstract
The present application describes techniques for fetching map data as a selected subset of entire map data available by selecting map data tiles corresponding to an area that encompasses a route. An amount of map data accessed may be adjusted based on a priority assigned to areas or points along the route. A sequence of map data may be accessed based on a priority assigned to sets of map data.
