Next Generation 9-1-1

Nex Gen 911 Call Center ImageNext Generation 9-1-1 (NG9-1-1) systems will rely more heavily upon GIS data to locate emergency callers. Currently, GIS data is often used to augment a 911 dispatcher’s ability to locate a caller. In a NG9-1-1 environment, GIS data will become the authoritative source to route calls to the correct 911 call center and dispatch the correct responders.

In order to understand how coordinated state GIS activities might best engage the NG9-1-1 community, the Geography Information Office (GIO Office) will continue to monitor the evolving technology and standards promulgation by the National Emergency Number Association (NENA). The GIO Office also often communicates with the Maryland’s Emergency Number Systems Board on GIS matters.
