| In order to provide E-911 service to an area, each habitable structure must be assigned a house number to a named street. In areas without formal street names or addresses, the information must be created. Using a WebGIS system, A&A develops an addressing scheme based on distance from a specified starting point, usually the beginning of a road. The addressing scheme is developed to account for any possible future building on the existing land. A&A then notifies the post office and phone company of the new street addresses. Once an E-911 call is received by the phone company, a database immediately recognizes the phone number and the corresponding E-911 address. Callers can be identified by their name, location, and phone number - a benefit for those who cannot complete their call. This information is then sent to the county dispatch center. Some dispatch centers operate through CAD (Computer Aided Dispatch) automated reporting which can show the area, mapping options, routing to the call from various rescue stations, and even what officers are already on call - all through GIS technology, developed with the help of A&A. A&A has developed E-911 systems for Floyd County, Giles County, Montgomery County, Smyth County, and Wythe County, Virginia; Sussex County, Delaware; and Lincoln County, North Carolina.
