NG9-1-1 Data Hacks: Finding Anomalies and Fixing Them
Monday, October 23, 2017, 1:00 - 5:00 PM (Half-Day)

Sandi Stroud, Michael Baker International, Virginia Beach, VA
Keri Brennan, GISP,  Michael Baker International, Indianapolis, IN

Attendance at this workshop will offer: 4.0 AICP credits

With the rapid deployment of NG911 technologies and the fact that GIS data is now mission critical information, the need to quickly and efficiently develop, deploy, cleanse and maintain Public Safety centric GIS data layers is becoming a task that may not have been high priority previously.  In this hands-on workshop, the attendees will learn the basics of quality control and quality assurance related to public safety data (address points, road centerlines, MSAG, ESN and PSAP boundary files). 


  • Students must bring a laptop with GIS software that can read sample GIS data (provide specific data formats)
    • Examples will be done using esri software and alternative software platforms will be discussed
    • Students must have a high level knowledge of GIS workflows and a working knowledge of NG 911 technology, terms and workflows


  • Review of point address, road centerline, PSAP boundaries, ESN Boundaries and MSAG or ALI data
  • Review of different data standards (FGDC, CLDXF, etc…)
  • Review of basic query techniques
  • Data comparisons, and error reports including:
    • Address points with missing data
      • Null geometry
      • Missing Street Name
      • Duplicate Points
      • Address not reflected in Centerline
      • Address out of order
      • Address out of range/wrong block
      • Address on wrong side of the street
  • Road Centerlines with missing data
    • Null geometry
    • Incomplete address ranges
    • Inconsistent To/From address range
    • Inconsistent Odd/Even address range parity
    • Potential parity flip
    • Overlapping address ranges
    • Inconsistent vector directionality

Learning Objectives:

  • Students will take away knowledge and skills to start an NG911 data tune up.
  • QA/QC processing in manageable, bite sized projects for quick and easy wins
  • Ways to begin the iterative process of data cleansing


  • Ability to query GIS data to look for anomalies
  • Review and fix anomalies
  • Understanging of how location is being handled with regards to data stewardship and to compliment other data when anomalies arise
  • Understand the data management issues that arise with maintaining GIS data for NG-9-1-1 and in support of enterprise GIS needs.

: One full-day or half-day workshop is included with full conference registration; $195 for workshop only or for second half-day workshop
