Reviewing Your Data
Next Generation 911 is completely in GIS environment
Old system used GIS more as reference
Legacy tabular data needs to fit into GIS
Master Street Address Guide (MSAG)
MSAG = Road Centerlines in NG911
QC/QA checks within a data layer
Examples of Internal QC’s
Unique ID check
Overlap in an Address Range
Road not intersected
Are Mandatory Field populated?
QC/QA checks between layers
MSAG compared to GIS road centerlines
Addresses compared to ALI and Road Centerlines, etc.
Important part of NG
Prevents fallout and ambiguity
Overlap in Address Range
Risk: When the same address range is present on more than one roadway, there is a large chance that a call may be routed or dispatched to more than one location and force a user to pick.

Fix: Review address numbers on each section and couple the ranges at the intersection.
Mandatory Field Values are Null
