US Patent 7710408 Centralized information management based upon position information

A system for information management comprises a central unit and a plurality of user units which are arranged to record information and send the information to the central unit. Particulars are stored in the central unit about a plurality of regions, each of which represents an area on at least one imaginary surface. One of the user units records information which comprises at least two coordinates and sends the information to the central unit. When the central unit receives the information from the user unit, it identifies to which region the coordinates belong and determines how the information is to be managed, based on the region affiliation.
