Abstract
Geographic data corresponding to a certain geographic area of offline coverage is stored in a memory of a computing device. An indication of a geographic boundary delimiting a region smaller than, and contained within, the geographic area is obtained. A current location of the computing device relative to the geographic boundary is determined and, in response to determining that the current location is outside the region, additional geographic data is retrieved via a wireless communication network to expand the geographic area of offline coverage. At least some of the geographic data corresponding to the expanded geographic area is provided via a user interface of the computing device when the computing device is offline.
