Southern IL GIS Mapping for Next Generation 9-1-1 Based

on NENA Standard Data Format

By: William BarrettAdviser: Dr Guangxing Wang

Introduction•What is Next Generation 9-1-1?

•Advancements in communications technology

Research statement

• Facilitate the development and implementation of a Geographic Information

Systems (GIS)-based Next Generation 911 (NG911) system for Southern

Illinois.

• Provide relevant stakeholders with standardized spatial datasets and an

advanced 9-1-1 system.

• Mapping the required geospatial data layers based on National Emergency

Number Association (NENA) standard data formats.

• Check and reduce errors and uncertainties, and conduct data quality control

and standardization.

• If possible, develop a conceptual model for quality control of products.

Research Questions

1. What are the major uncertainty sources of the existing

geospatial data layers?

2. How should the existing geospatial data layers be

converted from numerous data formats to meet the

requirements of the NENA standard data format?

3. What would be the best systematical methodology to

conduct quality control of data layers across the 9-1-1

maps created by the CSI?

Literature Review

• Data quality control issues (Karassenberg and Jong 2005)

• Position errors vs. attribute errors (Lunetta and Congalton1991)

• Identify and quantify errors and uncertainty (Pontius et al.

2000;2002)

• Uncertainty analysis methods (Wang et al. 2005)

• Making everything conform to the National Emergency Number

Association standard (NENA-02-010)

Study Area

• The 23 Counties of Southern IL.

Study Area

Methods

Anticipated Results• A Geographic Information Systems (GIS)-based Next

Generation 911 (NG911) system for Southern Illinois.

• Each county in the CSI group would have a standardized spatial

datasets that include

• Emergency service number (ESN), Public safety answering point

(PSAP), Structures, cell towers, roads, railroads….etc

• Guidelines for quality control of data layers

Significance of the Study

•Because of advancements in communications

technology.

•The way to reach 9-1-1 is changing.

•The existing 9-1-1 system was never intended to

receive calls and data from these types of

devices.

Significance of the Study

• This project will facilitate the development and

implementation of a GIS-based Next Generation 9-1-1

system for the multi-county area of southern Illinois

• If they can not find you they can not help you

• The tools that will be given to the 9-1-1 management will

be greater because of this project.
