Abstract
A method for efficiently fetching map tiles for digital maps includes receiving, at a client device such as a mapping user interface device, a request to display a digital map and identifying a plurality of map tiles for the request, each map tile representing a portion of the digital map. The user interface device generates a single map content request including multiple identifiers corresponding to the plurality of map tiles. The user interface device then sends the map content request to a map content server as a single request requesting multiple map tiles. In response to the map content request, the map content server retrieves the plurality of map tiles from a content database and sends the plurality of map tiles to the client device. The client device can then display the digital map based on the plurality of map tiles.
