System Tracks Cell Phone 911 Calls
(Southwest Times Record, July 6, 2004)

When cell phone users in Fort Smith
and Sebastian County call 911, their location information
pops up on a map on a computer screen allowing emergency personnel
to find the caller more quickly than before.
The same goes for land-line phones in residences, buildings,
businesses and phone booths.
Recently, the city and county began using microData GIS, a
map display software, as they implemented Phase II wireless
Enhanced 911 technology.
The percentage of cell phone calls in the area has increased
consistently during the past several years, keeping with the
national trend, said Cpl. Steve Hockaday, who works as a Geographic
Information System analyst at the Fort Smith Police Department.
A recent analysis of 911 calls from cell phones showed some
surprising results, he said.
"We went through and did a three-month study and found
that it was 56 percent which surprised us and well as several
other people," Hockaday said. "There was one month,
specifically, during the last year that was 71 percent."
Sebastian County had similar results, but the figures don't
resemble the number of emergencies, said Rusty Myers, assistant
executive director of Western Arkansas Planning and Development
District.
"When somebody sees an accident on the Interstate, you
don't get one cell phone call on it," Myers said. "You
get 10 because everybody calls on it. It doesn't mean that
the number of 911 incidents is higher, it's that they get
multiple calls when they get a cell phone deal."
Phase I provides a 911 call center with the telephone number
of a cell phone caller and oftentimes the location of a cellular
tower nearest to the caller. Phase II provides the call center
with the capability of receiving the telephone number as well
as latitude and longitude of a cell phone caller. This information
helps emergency personnel such as police or paramedics locate
the caller quickly.
The cost for the setup and implementation was more than $100,000.
A portion of that money is provided by the 50-cent surcharge
on monthly cell phone bills.
Carmen Bryant, administrator for the Arkansas Commercial Mobile
Radio Service, or wireless 911, said during the first quarter
of the year $760,000 was divided among 66 counties in Arkansas.
That money is used only for administrative costs. The other
portion of the surcharge is sent back to wireless carriers
for operational costs as it relates to 911. Bryant said checks
to carriers for this quarter total in excess of $2.5 million.
"That 50 cents a month that everyone pays for their wireless
911 service is collected by the carriers and it comes into
the board, and the board handles and distributes all that
money," Bryant said.
Fort Smith began addressing every point in the city down to
the apartment level in Global Positioning System in September
2001. The information was put into a mapping program. The
laborious process took six months, and then inspecting the
information took another six months.
"Your Phase II information is only as good as the GIS
data that you put into it," Hockaday said.
There are between 40,000 and 41,000 points including residences
and businesses that were addressed by police officers and
other city employees, Hockaday said.
The Western Arkansas Planning and Development District
contracted by Sebastian County plotted nearly 11,000 points
in Sebastian County excluding the city of Fort Smith, said
Rusty Myers, assistant executive director of WAPDD.
Myers believes the steps the city and county have taken in
upgrading their technology are remarkable.
"That by itself, even if you set aside the cell phone
thing altogether, is significant because before, all they
got was an address. ... But they certainly didn't get a map
on the screen showing exactly where that structure's located
so that they could be able to say to the emergency service
provider, take a right here, take a left here, and it's the
third house on the left," Myers said.
Hockaday agreed, saying that the city is leaps and bounds
ahead of where it used to be.
"There are a lot of people that we'll be able to locate
through Phase II technology," Hockaday said. "It's
impressive. You think about this 10 years ago; we would have
never thought about trying to do something like this."
Hammond provided a specific example of the improvements.
"Just the other day we had a call where a lady called
in and it was a cell phone and it sounded like she just dialed
911 on it and then set it down, but you could tell that she
and a man were arguing ... having a fight," Hammond said.
"Back with the old system we would have never been able
to find them. With the new system we were able to determine
exactly where she was and go right to her."
However, there are limitations, specifically when a person
uses an older-model cell phone to make the call. The phone
may not be GPS capable. Also, sometimes in buildings, signals
are lost and the information is not transmitted to the call
center.
"Like everything else, it's not perfect," Hammond
said. "Sometimes it just won't be there for whatever
reason, so you have to go back to the old way and just call
the cell phone number back and hopefully get the information
from the caller then."
Sam Neff, communications coordinator for the Sebastian County
Sheriff's Office, said there are other benefits to the mapping
software beyond pinpointing the caller on a map.
"Also, now this map is expandable to us and we can drag
it and we can see what's all around it, so if you need directions
to getting to where that call is, now then, you've got your
streets," Neff said.
The mapping software also has aerial photographs that allow
emergency personnel to see the topographical information.
This was used recently in Sebastian County when a suspect
tried to run over a sheriff's deputy on Glass Plant Road and
then fled into a wooded area.
Fort Smith police personnel utilized the technology to pull
up addresses of people living near a sex offender in order
to mail them a notification of their new neighbor. Prior to
that, police officers spent hours knocking on doors in neighborhoods
where a sex offender moved to.
While the new technology is helpful and puts emergency workers
in better position to aid someone in need much more quickly,
the 911 operator's map screen is dependent on the quality
of the GIS data - meaning GIS data requires constant maintenance
in order to provide accurate information to the call taker,
Fort Smith and Sebastian County authorities said.
"Phase II provides the x and y coordinates - latitude
and longitude," Bryant said. "They're talking down
the road about providing the z coordinate, which is the altitude.
That would make a difference like in high-rise buildings or
up there in the mountains, but that is not part of the mandate."
