Officials in Shelby County, Tenn., say they expect their 911 system to be more efficient after they build a new geographical information system map of their area, which includes Memphis. The process could cost as much as $6 million, because it involves mapping the county's almost 6,000 miles of streets and 482,000 structures. The city and county have several centers handling 911 calls, but the new system would ensure everyone was relying on the same location data.
