Improving offline map data availability

A computing device comprising:

• one or more processors;
• and
• a memory implemented as a non-transitory computer-readable medium storing thereon instructions that, when executed by the one or more processors, cause the computing device to:
• store, in the memory, geographic data corresponding to a certain geographic area of offline coverage,
• obtain an indication of a geographic boundary delimiting a region smaller than, and contained within, the geographic area,
• determine a current location of the computing device relative to the geographic boundary,
• in response to determining that the current location is outside the region, retrieve additional geographic data via a wireless communication network to expand the geographic area of offline coverage;
• and
• provide at least some of the geographic data corresponding to the expanded geographic area via a user interface of the computing device when the computing device is offline.

A method for providing geographic data to client devices for offline use, the method comprising:

• receiving, by one or more processors from a client device via a communication network, an indication of a current location of the client device;
• identifying, by the one or more processors, geographic data to be provided to the client device to define an area of offline coverage, including determining boundaries of the area of offline coverage based on an amount of geographic data the client device is expected to receive prior to reaching certain points within the area of offline coverage;
• and
• providing the geographic data to the client device.

A server device comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium storing thereon instructions that, when executed by the one or more processors, cause the server device to:
• receive, from a client device via a communication network, an indication of a current location of the client device,
• identify geographic data to be provided to the client device to define an area of offline coverage, including determine boundaries of the area of offline coverage based on an amount of geographic data the client device is expected to receive prior to reaching certain points within the area of offline coverage, and
• provide the geographic data to the client device.
