NENA Intellectual Property Rights Disclaimer On behalf of the National Emergency Number Association, I welcome you to this meeting. It is

essential that we observe certain ground rules as we participate in this meeting. Antitrust laws

of the United States prohibit the discussion of a number of matters in a meeting such as this. It

is important that discussions at this meeting address only that information needed for

prices; terms and conditions such as credit terms, markups, or profits; geographical areas in

which a company or companies seek or may seek to do business; the persons or companies

with whom a company or companies will or will not do business; production costs; or any future

marketing plans.

Any departure from these ground rules could result in severe civil and criminal penalties to you

WelcomeNENA GIS Data Model for NG9-1-1

Standard

Goals for todayHigh level overview of issuesDocument structureMajor discussions and decisions Discussion of Issues


Workgroup HistoryWork Started Late 2011Meetings held weekly with some notable

exceptionsDocument has gone through Authoring

Review Currently addressing Issues brought up

after Authoring Review


Membership 67 Members Over ½ of members work for 9-1-1

Authorities Incredible Depth of Knowledge of Public

Safety GIS


Scope and PurposeThis document updates previous GIS Data Models for use in the NG9-1-1 system while remaining backwards compatible with existing E9-1-1 GIS data needs.

The new GIS Data Model is designed to support the location conveyed in the PIDF-LO but will work with ALI as one moves to NG9-1-1.


Benefits

Establish standardized GIS data

provisioning requirements and

structure for all users

Establish guidelines for GIS data

needed to support existing E9-1-1

systems, while transitioning into NG9-

1-1 systems


Benefits

Enable compatibility and interoperability

Facilitate GIS data provisioning to NG9-1-1

functional elements

Promote consistent data elements for software

development

Provide a framework to help migrate existing GIS

datasets to i3 Next Generation 9-1-1 systems

Streamlines data maintenance

Remaining Issues

Authorative Boundary

This required layer describes the polygon

boundary that defines the geographic area for

which the GIS data is authoritative


Remaining IssuesRoad Name Alias Table

The recorded legal road name as assigned by the

local addressing authority should be the name

used in the Road Centerlines,

however

Alias road names are common and must be

considered


Remaining Issues

Road Name Alias Table

This outlines an example of a data structure that

can be used to create a related table of alias road

names

Local 9-1-1 Authorities may already have a

methodology in place to manage alias road names


Remaining Issues


Regardless of which method is used to define alias

road names, it is up to the 9-1-1 Authority to ensure

the methods they use are compatible with the NG9-

1-1 system and all other software and applications

that will use the alias methodology


Remaining Issues


To ensure proper civic location validation by the LVF

and proper routing by the ECRF, a standardized

method of maintaining alias road names is required

The use of this Road Name Alias Table will facilitate

the sharing of data in a consistent manner by

various local 9-1-1 Authorities

represent the cell sectors. Cell sectors must be
