FGDC Address Data Standard • 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
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
Organization of the FGDC Standard • Data Content • Data Classification • Data Quality • Data Exchange • Two profiles: USPS and NENA (still in draft)
Number, Subaddress and Street Name Elements • Address Number Elements • Address Number Prefix • Address Number • Address Number Suffix • Complete Address Number • Street Name Elements • Street Name Pre-Modifier • Street Name Pre-Directional • Street Name Prefix Type • Separator Element • Street Name • Street Name Suffix Type • Street Name Suffix Directional • Street Name Post Modifier • Subaddress Elements • Subaddress Type • Subaddress Identifier • Subaddress Element • Complete Subaddress • Intersection Corner Elements • Corner Of
Landmark, Place Name and Postal Elements • Postal Elements • USPS Box Type • USPS Box ID • USPS Box Group Type • USPS Box Group ID • USPS Route • USPS Box • USPS Address • USPS General Delivery Point • Landmark Elements • Landmark Name • Complete Landmark Name • Place Name Element • Place Name • Attribute: Place Name Type
Address Attributes • Identify records • Support geometry • Describe status • Provide base information for quality assurance • Connect addresses to other features and other addresses
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.
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
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
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
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
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.
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
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
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.
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
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.
