  • Scope, Status, and Structure
  • United States Street, Landmark, and Postal Address Data Standard"
  • Scope: Street, landmark, and postal addresses in the United States
  • Status: FGDC-endorsed standard
  • Structure: One data standard in four parts:
    • Data Content
    • Data Classification
    • Data Quality
    • Data Exchange
slide2

Purpose of the Standard

  • Provide a systematic basis for recording all addresses in the United States
  • Provide one standard that meets the address data management needs of:
    • Local address administrators
    • Emergency response and navigation
    • Postal and package delivery
    • Administrative recordkeeping
    • Address data aggregation
  • Support best practices in address data management
slide3

  • Data Quality
  • Data Exchange
    • Two profiles: USPS and NENA (still in draft)

slide6

Address Attributes

  • Identify records
  • Support geometry
  • Describe status
  • Provide base information for quality assurance
  • Connect addresses to other features and other addresses
slide7

Address Data Quality

  • Identifies elements of Address Data Quality
  • Supports testing of tabular and spatial data
  • Describes testing procedures (38 tests)
  • Provides base information for quality assurance
  • Each test provides information about methodology, reports, and how used.
    • Example code is also provided.
slide8

Address Data Exchange

  • Provides an XML protocol for seamless exchange of data
    • Federal Standard requires use of XML
    • Protects data producers and data consumers
    • Flexible exchange –missing fields on either side do not affect transfer
    • Useful in on-going exchange and aggregation efforts
slide9

Federal, State and Local Adoption and Use

  • Census and other federal agencies are using the Standard
  • Several states, counties and cities have adopted the standard, and are implementing data models that use it
  • Planning to work with other Federal agencies to develop profiles for their use
  • Planning to propose Addresses as the eighth data theme in the NSDI Framework
slide10

Benefits of the Standard

  • Quality is an integral part of the data
  • Model for exchanging data in a standard way
  • Definitive syntactical logic for address data
slide11

NENA NG9-1-1 CLDXF Standard

Civic Location Data Exchange Format

NENANext Generation Data Development Working Group

NENA Next Generation 9-1-1 (NG9-1-1) United States Civic Location Data Exchange Format (CLDXF) Standard

slide12

What Is CLDXF?

  • Standardized way to exchange 9-1-1 call civic location(address) information
    • Created by NENA NGDD WG as part of NG9-1-1 suite of standards
    • Status: Not yet adopted.
  • Profile of IETF Geo-priv PIDF-LO
  • Related by profile to the new FGDC address data standard
    • A profile restricts or extends a base standard(without contradicting it) for a particular application.
slide13

CLDXF Contents

  • Elements needed to compose addresses in 9-1-1 call records:
    • Country, state, and place names and codes
    • Street name elements
    • Address number elements
    • Landmark name
    • Subaddress elements
slide14

What CLDXF Excludes

  • Addresses that are unacceptable in 9-1-1 call records:
    • Intersection addresses
    • Address ranges
    • PO Box, RR and similar addresses
  • Information not needed in the address portion of a call record:
    • Address IDs and attributes
    • Address classes
    • Address quality tests
slide15

Creating the CLDXF – FGDC Profile

  • Compared the business purposes of the standards
  • Determined which address classes and elements were needed for NENA purposes
  • Mapped FGDC elements and NENA elements to each other
  • Compared the element definitions, examples, notes, etc. in complete detail. Noted all discrepancies.
  • Reviewed FGDC address classes and determined which were useful in CLDXF.
  • Within the profile, restricted or extended the FGDC standard as needed to accommodate discrepancies and exclusions.
  • Listed the steps needed to convert between NENA and FGDC address records.
slide16

What\'s in the Profile?

  • Detailed, element by element comparison of FGDC and NENA elements
  • Which NENA element corresponds to which FGDC elements
  • Discrepancies, comparisons, reconciliation
  • Other restrictions and extensions: parts, classes, domains of values
  • Step-by-step task list for converting address records between NENA and FGDC standards.
  • Conformance requirements
slide17

Result

  • Address data exchange will be included in the NG9-1-1 suite of standards
  • CLDXF will be a NENA standard and statement of best practice for voluntary adoption by PSAPs nationwide.
  • CLDXF conforms to the IETF PIDF-LO but makes it US-specific.
  • CLDXF and FGDC standards are tightly related.
  • Address data managers can exchange data across the standards.
  • The three standards reinforce each other.
