Abstract

A method may include accessing service data associated with a service and associated with a group of geographical regions. The method may also include assigning at least some of the service data of the group of geographical regions corresponding to a map tile. The method may include generating an initial batch of service data corresponding to the map tile, thereby generating initial batches of service data. The method may also include receiving, from a mobile device, a request to download map data corresponding a geographical area. The method may also include determining one or more map tiles corresponding to the geographical area. The method may also include determining a subset of the initial batches associated with the one or more map tiles corresponding to the geographical area. The method may also include providing, to the mobile device, the subset of the initial batches responsive to the request.
