The Emergency Communications District of Shelby County, Tennessee, Improves 911 Call Plotting and GIS Data Using Nearmap’s Aerial Imagery

The district has implemented high-resolution, aerial imagery to aid
in geocoding and plotting new roads into 911 mapping systems to improve
GIS Data for public safety and law enforcement

SOUTH JORDAN, Utah–(BUSINESS WIRE)–#aerialimagery–The Shelby County, Tennessee, Emergency Communications District has
implemented Nearmap
high-resolution aerial imagery to geocode and plot new addresses and
developments into the 911 mapping systems to help fire and rescue,
emergency medical services and law enforcement get instant access to
updated maps containing GIS data needed to get to the right locations as
soon as possible.

The Emergency Communications District is responsible for
establishing local emergency telephone service, providing the network
call-handling equipment, and updating the geographic information systems
(GIS) data for each Public Safety Answering Point (PSAP) within Shelby

Nearmap provides frequently-updated, high-quality aerial captures to
ensure that the District’s GIS Data, geocoding and the 911 mapping
systems are up to date, providing public safety and law enforcement the
most accurate information.

Benefits of Nearmap aerial imagery for the Emergency Communications
District include:

  • The imagery is delivered through the cloud as a subscription service,
    making it accessible to all team members via mobile and desktop.
  • Nearmap imagery is taken at least twice a year, both leaf-on and
    leaf-off to provide different views of locations in different seasons.
  • Aerial captures integrate directly into ArcMap, ArcPro and ArcGIS
    Online applications, so GIS information can overlay directly onto the
    high-resolution imagery.

Before Nearmap, Shelby County’s aerial image process required a
contracted flight to photograph the county areas. Because of the high
cost of capturing those images, the county purchased images once every
two years, after pooling resources from various county entities.

“With our old aerial imagery provider, there were issues with
mosaicking separate images together, and since the imagery was taken
every two years, many rural and unincorporated areas were out of date,”
said Timothy Zimmer, the GIS Administrator for Shelby County’s Emergency
Communications District.

With out of date images, the county had to develop alternate methods to
locate addresses for the 911 systems. Now, the combined impact of data
services, base maps, Nearmap imagery, and third-party data are improving
all aspects of public safety, including law enforcement, fire, and
emergency medical services. Even other agencies are using the district’s
imagery and GIS data.

“There’s a certain context and currency you can get from Nearmap imagery
that you simply can’t get from any other imagery products,” Zimmer said.
“Other agencies, such as the County Clerk and the Utility Company, are
using our addressing data because Nearmap has helped enable us to be
much more current.”
