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 first route and to an area encompassing a secondary route based on the first route. An amount of map data accessed may be adjusted based on a priority of the secondary route.
