Abstract
An API for prefetching map data receives a prefetch request for an indicated geographic area from a software application. In response, the API retrieves map data corresponding to the indicated geographic area from a map data provider and stores the map data in a map data cache without causing a digital map based on the map data to be displayed on the display device. The map data cache is accessible to the software application only via the API. Subsequently to storing the map data in the map data cache, the API receives a request to render the digital map from the software application and, in response to the request to render the map image, renders the map image for display on a display device using the map data stored in the map data cache.
