BVCOG’s regional GIS program assists the county database
maintenance projects in Burleson, Grimes, Leon, Madison, Robertson, and
Washington counties with mapping, validation and data processing associated
with rural addressing for 9-1-1. Each county has a database
maintenance/addressing coordinator that is responsible for assigning addresses
to new structures and mapping new roads in the rural part of the counties. Additionally, each county coordinator is
responsible for maintaining the Master Street Address Guide (MSAG), updating
the county maps with new roads and driveway point data, coordinating changes
with municipalities and correcting errors in the 9-1-1 database.
BVCOG’s 9-1-1 GIS program
implemented fully enhanced 9-1-1 Mapped Automatic Location Identification (ALI)
systems at the 7 regional PSAPs. Mapped ALI is the geographic display of the 9-1-1
call and text message on a digital map.
Landline calls that have physical addresses and are accurately displayed
on Mapped ALI, however wireless and text messages display an approximate
location usually within 150 meters.
