GIS stands for Geographic Information System. It is a system that creates, evaluates, manages and maps several data types. 

The GIS lays all these data points over a map to visually describe and evaluate the location of the emergency caller and their surrounding area. 

This allows public safety answering points (PSAPs) and other public safety agencies to understand the situation better and improves communication between emergency call centers, 911 callers, and first responders. 

How does NextGen 911 use GIS information? 

NextGen 911 is designed to support wireless communications and provide emergency callers with immediate access to PSAPs and a faster overall emergency response. It enables emergency calls to be mapped by exact coordinates or addresses, and the GIS data validates this information, thus routing 911 calls to the correct PSAP. 

GIS data is used in two primary functions of NexGen911 services:

1. 911 call routing: The emergency call routing function determines which 911 call center to route the caller using GIS data geospatially. It can also support real-time texting, voice messaging, and photo and video streaming to public safety organizations. 
2. Emergency caller location validation: The 911 caller location validation function identifies the location of an address (street names and home numbers). GIS The Department of Public Safety division of Emergency Communication Networks (ECN) oversees the Minnesota NextGen 911 program; in collaboration with the Geospatial Information Office and Statewide Emergency Communications Board (SECB), data is used with the location validation function to validate accurate emergency caller locations. 

Helping ensure the 911 call is accurately routed to the closest possible PSAP for faster emergency response.
