GIS Assists in Updating Reverse 911 Data


The Village of Tinley Park, IL uses a public safety communications
system known as Reverse 911. This critical administrative tool is used
to communicate important or time sensitive information to groups of
people in a defined geographic area. The system uses a database of
telephone numbers and associated addresses, which, when tied into the
village’s Geographic Information System (GIS), can be used to deliver
recorded emergency notifications to a selected set of telephone service
subscribers within the village limits.

By leveraging GIS applications, and a standardized address model, the
process of updating reverse 911 data has become a more efficient
process. Along with making the process more efficient, GIS also provides
a more accurate database for the reverse 911 system which, in an
emergency, can make all the difference.
