Abstract: A computing device includes processor(s), memory(s), and network interface(s). The processor(s) is configured to: cause the computing device to request mapping data for a particular physical location from a remote server using the at least one network interface; receive a unique identifier for the mapping data for the particular physical location from the remote server using the at least one network interface; cause the computing device to query a plurality of network nodes using the unique identifier to identify at least one network node of the plurality of network nodes that can provide the mapping data associated with the unique identifier, wherein the plurality of network nodes does not include the remote server; and receiving the mapping data from the at least one network node identified as being able to provide the mapping data associated with the unique identifier.
