Abstract: A system and method for communication of information that has particular significance to a specific location only to those individuals that are at or near that geo-spatial location. In particular, providing safety factor data and alerts is a preferred use of the invention. The invention allows information to be tailored to the individual at that location by selectively filtering what is communicated and what is not. The system includes a transmitting proximity event server, a GPS client wireless component that can be a personal wireless communication device (such as Palm Pilot, cellular digital phones, etc.) or personal computer configured for use within a global position satellite network.
