NENA Information Document for GIS Data Stewardship for Next Generation 9-1-1
|Document Type: || Information|
This document will assist Geographic Information Systems (GIS) and Public Safety Answering Point (PSAP) staff in understanding and adopting best practices related to managing specific GIS datasets in support of Next Generation 9 1 1 (NG9 1 1) deployments. GIS data are at the heart of NG9 1 1 systems. Civic addresses associated with fixed caller locations are validated against GIS data to ensure that they can be mapped. When an emergency call is made, it is routed using the caller’s location along with the GIS boundaries of responder agencies to determine the correct responder.
The purpose of this document is to support the development of complete, accurate and current GIS datasets to be used within NG9 1 1 systems. These datasets will be used to validate call location information, to route calls to the correct responding agency, and to display locations in context for call handling purposes. Following the recommendations presented will result in more accurate, efficient and reliable operation of GIS data dependent services within NG9 1 1 Systems.
