Solving the 9-1-1 Mapping Problem with GPS

Keith Cunningham

Abstract:	The NAVSTAR Global Positioning System has been tested to determine its usefulness for address assignment in the implementation of rural enhanced 9- I - I emergency telephone systems. Rural counties across the nation are implementing enhanced 9- I-l emergency telephone number systems. The proper functioning of an enhanced 9-I- I system requires the assignment of a “city-style” address to each telephone number, therefore entire counties must be readdressed because P.O. Boxes and Rural Delivery Boxes do not logically identify the location of a 9-I- I caller. Addresses have been traditionally determined via photogrammetry and field work. and a GIS is often used to manage the data. GPS linked to field data collectors has been found to speed the address assignment process by permitting a “one-stop” field inspection to collect the positions of houses and driveways together with the information required for 9- I-I service.
