    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 4. Purpose and Scope
    • "United States Street, Landmark, and Postal Address Data Standard"
    • Draft standard to be submitted to the Federal Geographic Data Committee (FGDC)‏
    • One standard in four parts:
      • Data Content
      • Data Classification
      • Data Quality
      • Data Exchange
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 5. Goals
    • Provide a statement of best practices for street address data content and classification
    • Define tests of street address data quality
    • Facilitate exchange of address information
    • Offer a migration path from legacy formats to standards-compliant ones
    • Provide for different levels of standardization
    • Build on previous FGDC address standard efforts
    • Make this standard compatible with, and supportive of the FGDC framework standard for geospatial data, and with the NENA and USPS address standards.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 6. Standard Development Process
    • Sought broad awareness and participation
      • Wiki collaborative website
      • Teleconferences
    • Posted drafts for public comment via web form
      • Received over 350 comments from public and private sector
    • Focused on practical needs and usefulness
      • Local emphasis: Where addresses are created and used the most
      • Quality is integral to address use, must be built-in to process
    • Included both tabular and geospatial data
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 7. Organizing Principles
    • Definition of an address:
      • "An address specifies a location by reference to a thoroughfare, or a landmark; or it specifies a point of postal delivery."
    • Elements and Classes: A syntactical approach to address classification.
      • The standard classifies addresses according to their address elements and the order in which the elements are arranged.
    • Address Reference Systems:
      • Addresses are created locally based on local rules for naming and numbering.
    • Data Quality
      • The quality of address data must be measured against Address Reference System rules and recorded.
    • Data Exchange
      • Address data must be able to be seamlessly exchanged between different users.
    • All of these must be incorporated into a comprehensive address data standard.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 8. Address Elements
    • Address numbers and their components
    • Street names and their components
    • Subaddresses (suites, rooms, etc.) and their components
    • Landmark names
    • Larger areas (place names, states, postal codes, and country names)‏
    • USPS postal address elements (PO Box, RR, etc.) and their components
    • USPS address lines (per USPS Pub 28)‏
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 9. Address Attributes
    • Purpose: documentation, mapping and quality control
    • Key attributes include:
    • Address identifier (required)‏
    • The address authority, dataset, and start and end dates
    • Geographic coordinates
    • Lifecycle and official status
    • Class
    • Feature type
    • Relationship to cadastral and transportation features
    • Attributes for quality control (parity, sequence, relationships, etc.)‏
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 10. Element Definitions
    • Name, definition, and data type
    • Existing standards (if any),
    • Domain of values (if any),
    • Extensive examples and explanatory notes
    • XML tag, XML model, and XML example
    • Data quality measures and notes.
    • Elements may be simple or complex.
      • Complex elements are simple or other complex elements grouped together
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL

    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 12. Address Reference Systems
    • The local geographic framework and business rules for address assignment.
      • Basis for testing the quality and validity of an address
      • Defines the elements needed to compose and describe it.
        • Defines boundary and internal geographic structure of the area governed by the business rules, and the authority for those rules
        • May include rules for naming streets and for assigning address numbers along them.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 13. Data Quality
    • A complete suite of data quality tests.
      • Covers all address elements, attributes, and classes.
      • Tests of address location relative to Address Reference System and known features
        • Tests address data relative to local business rules
        • Measure how well a given set of address records conforms to the standard.
      • Each test specification includes the scope, measure, and procedure of the test, and a script in SQL pseudocode.
  • 14. Data Exchange
    • Requires open, standardized format:
      • XML Schema Document (XSD) and XML.
      • Protects data producers and consumers
      • Allows localizations, but provides standard form for exchange.
    • XSD provides a data model, but not a database model.
      • Organizational database requirements and relationships vary considerably.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 15. Implementing The Standard
    • The standard does not require incorporation of every element and attribute.
      • For example, if none of the addresses in a given area have any Address Number Prefixes, that element may be omitted from the address records for that area.
    • The standard does not require parsing every address into its simplest elements, nor does it require creation of a complex address data base.
      • The standard recognizes and supports different levels of complexity, from the two-line format prescribed in USPS Publication 28 to a fully-parsed, normalized database.
    • The standard does not require use of the address attributes, although some attributes are essential for most purposes.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 16. Why A Standard is Needed
    • Addresses are primarily created and maintained locally.
    • Address data is often poorly understood, badly recorded, and not well documented.
    • The lack of a standard impedes the ability of local jurisdictions to share data internally, with each other, and with regional, state and federal agencies.
    • As states create state-wide address database, the task of standardization and quality assurance becomes enormous. Standards help organize and simplify this process.
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 17. Benefits of Implementing the Address Standard
    • The standard supports the full range of address data needs, at all levels of government and in the private sector.
      • Address management
      • Government administration
      • Emergency response
      • Postal delivery
      • Data exchange and aggregation
    NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  • 18. Why Should You Implement the Standard?
    • It supports a comprehensive view of addresses that responds to needs for organization, quality, documentation, and exchange of address information.
      • Broad participation provided information about differing address practices throughout the U.S.
      • Testing of the standard in real situations insured its usefulness and viability.
    • It provides a path for moving from legacy systems that contain addresses to enterprise management that uses addresses as the key to data throughout government organizations.
      • Improved efficiency and economy: saves time, money and lives.b
