Southern IL GIS Mapping for Next Generation Based on NENA Standard Data Format By: William Barrett Adviser: 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 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 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 )
Study Area The 23 Counties of Southern IL.
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 is changing. The existing 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 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 management will be greater because of this project.
