Abstract
A hierarchical floating car data network comprises a central server, an egress point network, and a participating vehicle network. The egress point network is in communication with the central server. The egress point network comprises a plurality of egress points. The participating vehicle network comprises a plurality of participating vehicles. At least some of the plurality of participating vehicles are in direct communication with each other. At least some of the plurality of participating vehicles are in communication with at least some of the plurality of egress points. Furthermore, at least some of the plurality of participating vehicles may be in communication with the central server. A geographic database is formed from content communicated between the elements of the hierarchical floating car data network.
