“NG9-1-1 UTILIZES GIS DATA FOR 9-1-1 EMERGENCY CALL ROUTING FUNCTIONS AND LOCATION VALIDATION FUNCTIONS (ECRF/LVF)”

NATIONAL 9-1-1 MAP DATABASE, GeoComm / Esri Whitepaper, May 13, 2016

ECRF

The Emergency Call Routing Function (ECRF) accurately routes 9-1-1 calls to the appropriate PSAP based on the caller’s location and in a NG9-1-1 system, the ECRF along with the Location Validation Function (LVF) replace the current Master Street Address Guide (MSAG).

PUBLIC SAFETY ANSWERING POINT (PSAP)

A PSAP is an answering location for E9-1-1 calls originating in a specified area.

MASTER STREET ADDRESS GUIDE (MSAG)

An MSAG is a compressed listing of every street name, house number range, community, and Emergency Service Number (ESN) for a community.

The MSAG defines all possible valid address locations within the 9-1-1 service area.

The MSAG enables proper routing of E9-1-1 calls and display of appropriate emergency response agencies to the PSAP call taker.

WHY USE GIS FOR ECRF?

Geospatial call routing enables more accurate call routing than traditional E9-1-1 systems and can reduce the number of 9-1-1 call transfers due to misrouted 9-1-1 calls. This in turn can help reduce emergency response times and save more lives and property.

LOCATION VALIDATION FUNCTION (LVF)

In addition to being used when routing 9-1-1 calls, NG9-1-1 systems use GIS data before a 9-1-1 call is placed to see if the address is valid for 9-1-1.

The GIS data provisioned to the LVF is identical to the GIS database provisioned to the ECRF.

BENFITS OF NG911

• Ability to receive voice, video, text, or data sent over IP networks from various communications devices (e.g., wireline, wireless, VoIP, sensors, etc.) – making 9-1-1 more accessible for all users

• Automatic and advanced data sharing between all public safety responders, PSAPs, emergency management, traffic operations, etc. – The ESInet has been designed as an Emergency Services network, not just a “9-1-1 network”. This network can provide access to public safety databases, remote systems, provide transport for Radio over IP (RoIP), etc. – Data is shared from the caller to PSAP to dispatch to responders and beyond – NG9-1-1 is designed to be flexible, open, non-proprietary (standards-based), and a secure interoperable internetwork (a “system of systems”)

• Advanced call handling processing and dynamic routing of callers based on caller’s geographic location and most appropriate PSAP – Rule-based configurability and control for PSAPs and 9-1-1 Authorities

WHAT IS THE ROLE OF GIS IN NG911?

IS THE ROLE OF GIS IN NG 911 ONE OF PROVIDING LOCATION DATA OR ONE OF GEOSPATIAL ANALYSIS, OR BOTH?

A. THE ROLE OF GIS IN NG911 IS TO PROVIDE ACCURATE LOCATION DATA TO SUPPORT CALL ROUTING FUNCTIONS

AND LOCATION VALIDATION FUNCTIONS

Required Data

• Address points

• Road centerlines

• PSAP boundaries

• ESA boundaries

• Orthoimagery

Optional Data

• Local Administrative Boundaries

• Land Parcels

• Structures (Strong need for structures on “campuses”

ADDRESS POINTS• Currently part of voluntary Data Sharing Initiative• Address point locations vary by county

• Who maintains the data? Varies. Usually the PSAP director maintains the MSAG, required updates in 24 to 48 hours. Only updated when a range needs extended, or new street, or street name change.

• Kinds of address points:• Access to property from road/highway• Center of dwelling• Center of parcel

• Which is most useful to NG 911? Dwelling is first choice, but the ESRI community data model has place for both dwelling and entrance points that share same address.

• Can all be of use if we document what it is? Yes.• Multiple residences in one location (example: apartment

building, or college dorms) handled differently county-by-county. ESRI model places stacked points.

ROAD CENTERLINES• How will centerlines be used?

• 2nd level of data for address matching? Yes

• Routing? Yes (for dispatch, not NG911)

• Address ranges needed

• Currently part of voluntary data sharing initiative

• Address ranges and attributes differ by county

• Updates are performed at different intervals

PSAP BOUNDARIES• Does this data exist in either paper

or GIS form? Not statewide.

• 126 Indiana PSAPs

• State Police boundary overlap other PSAP boundaries but are mostly around major roads

EMERGENCY SERVICE AREA BOUNDARIES

• Does this data exist in either paper or GIS form? No.

• Kosciusko has 40 or 50 of these.

ORTHOIMAGERY• Currently being updated for State

• Base product: 1 foot resolution, 4-band, leaf off

• About 1/3 of counties will buy-up to 6” resolution

OPTIONAL DATA SETS

Political Boundaries Land Parcels Structures

OTHER CONSIDERATIONS

Liability for inaccurate data

• “National 9-1-1 Map Database participation must not increase liability of participants. There must be a legal framework for managing and mitigating liability risks for GIS software and service providers, and authoritative sources of map information fed into the National 9-1-1 Map Database, otherwise fear of liability and lawsuits may prevent authoritative sources and vendors alike from participating.”

• Legislation needed?

OTHER CONSIDERATIONSAvailability of Required Data• Address points, road centerlines, and local administrative boundaries are

part of current data sharing initiative. Sufficient?

• Building PSAP boundary data is manageable (126 PSAPs)

• Do you have Emergency Service Areas mapped?

• Future orthoimagery funding is not certain.

• Structures? What is business case? (Ortho + LiDAR + processing + QC)

OTHER CONSIDERATIONS

Requirements of GIS Databases

“The National 9-1-1 Map Database must support NG9-1-1 PSAP mapping systems (GIS data contained in the database must be downloadable and consumable by 9-1-1 PSAPs) and must be capable of providing NG9-1-1 Location to Service Translation queries…”

• Complete data

• Share data

• Aggregate and prepare data

• Address legal issues
