Next Generation 9-1-1
GIS data plays a critical role in Next Generation 9-1-1 (NG9-1-1). In the NENA i3 NG9-1-1 architecture, all calls are routed based on location, including wireline 9-1-1 calls. This presents new challenges and requirements for local and regional GIS data planning and management.
There are two important issues to consider when planning a GIS data development and maintenance program to support NG9-1-1.
- GIS data will have a heightened degree of criticality because all calls will be routed to NG9-1-1 ESInets and Public Safety Answering Points (PSAPs) geographically based on a caller’s location and a point in polygon selection process.
- GIS data, MSAG, and ALI database synchronization is even more crucial to properly determine the location of calls.
GIS data has an expanded role in NG9-1-1 based on all the spatial, geographical routing that will happen within NG9-1-1. Currently, GIS data for 9-1-1 is used to locate the address of an incident. With NG9-1-1, GIS data will manage where the 9-1-1 call is routed. In other words, identifying which PSAP will receive the call based on geography.
As GIS data is used for geographically routing calls between PSAPs, there are many considerations:
- Are there additional data layers that will assist in routing calls to correct PSAPs?
- What data guidelines should be followed to ensure accuracy, consistency, and increased performance for emergency responders?
- Will GIS data be more regionalized?
- How will data sharing be set up between neighboring agencies?
- What are the policy decisions necessary to guide on-the-fly 9-1-1 call routing boundary polygon changes?
- How are GIS, MSAG, and ALI database synchronization measured, maintained, and guaranteed?
- How does a local GIS data development and maintenance program interact with telecommunications service providers (TSPs), 9-1-1 ALI database and service providers, and 9-1-1 telephony equipment vendors?
