  7. 7. Organizing Principles <ul><li>Definition of an address: </li></ul><ul><ul><li>&quot;An address specifies a location by reference to a thoroughfare, or a landmark; or it specifies a point of postal delivery.&quot; </li></ul></ul><ul><li>Elements and Classes: A syntactical approach to address classification. </li></ul><ul><ul><li>The standard classifies addresses according to their address elements and the order in which the elements are arranged. </li></ul></ul><ul><li>Address Reference Systems: </li></ul><ul><ul><li>Addresses are created locally based on local rules for naming and numbering. </li></ul></ul><ul><li>Data Quality </li></ul><ul><ul><li>The quality of address data must be measured against Address Reference System rules and recorded. </li></ul></ul><ul><li>Data Exchange </li></ul><ul><ul><li>Address data must be able to be seamlessly exchanged between different users. </li></ul></ul><ul><li>All of these must be incorporated into a comprehensive address data standard. </li></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  8. 8. Address Elements <ul><li>Address numbers and their components </li></ul><ul><li>Street names and their components </li></ul><ul><li>Subaddresses (suites, rooms, etc.) and their components </li></ul><ul><li>Landmark names </li></ul><ul><li>Larger areas (place names, states, postal codes, and country names)‏ </li></ul><ul><li>USPS postal address elements (PO Box, RR, etc.) and their components </li></ul><ul><li>USPS address lines (per USPS Pub 28)‏ </li></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  9. 9. Address Attributes <ul><li>Purpose: documentation, mapping and quality control </li></ul><ul><li>Key attributes include: </li></ul><ul><li>Address identifier (required)‏ </li></ul><ul><li>The address authority, dataset, and start and end dates </li></ul><ul><li>Geographic coordinates </li></ul><ul><li>Lifecycle and official status </li></ul><ul><li>Class </li></ul><ul><li>Feature type </li></ul><ul><li>Relationship to cadastral and transportation features </li></ul><ul><li>Attributes for quality control (parity, sequence, relationships, etc.)‏ </li></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  10. 10. Element Definitions <ul><li>Name, definition, and data type </li></ul><ul><li>Existing standards (if any), </li></ul><ul><li>Domain of values (if any), </li></ul><ul><li>Extensive examples and explanatory notes </li></ul><ul><li>XML tag, XML model, and XML example </li></ul><ul><li>Data quality measures and notes. </li></ul><ul><li>Elements may be simple or complex. </li></ul><ul><ul><li>Complex elements are simple or other complex elements grouped together </li></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  11. 11. Address Classes <ul><li>Thoroughfare Address Classes </li></ul><ul><ul><li>Numbered Thoroughfare Address: 123 Main Street </li></ul></ul><ul><ul><li>Intersection Address: Fifth Avenue and Main Street </li></ul></ul><ul><ul><li>Two-Number Address Range: 405-411 West Green Street </li></ul></ul><ul><ul><li>Four-Number Address Range: 900-962, 901-963 Milton Street </li></ul></ul><ul><ul><li>Unnumbered Thoroughfare Address: Forest Service Road 698 </li></ul></ul><ul><li>Landmark Address Classes </li></ul><ul><ul><li>Landmark Address: Statue of Liberty </li></ul></ul><ul><ul><li>Community Address: 123 Urbanizacion Los Olmos </li></ul></ul><ul><li>Postal Delivery Address Classes </li></ul><ul><ul><li>USPS Postal Delivery Box: PO Box 16953 </li></ul></ul><ul><ul><li>USPS Postal Delivery Route: RR 1, Box 100 </li></ul></ul><ul><ul><li>USPS General Delivery Office: General Delivery </li></ul></ul><ul><li>General Class </li></ul><ul><ul><li>Mixed or unknown class </li></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  12. 12. Address Reference Systems <ul><li>The local geographic framework and business rules for address assignment. </li></ul><ul><ul><li>Basis for testing the quality and validity of an address </li></ul></ul><ul><ul><li>Defines the elements needed to compose and describe it. </li></ul></ul><ul><ul><ul><li>Defines boundary and internal geographic structure of the area governed by the business rules, and the authority for those rules </li></ul></ul></ul><ul><ul><ul><li>May include rules for naming streets and for assigning address numbers along them. </li></ul></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  13. 13. Data Quality <ul><li>A complete suite of data quality tests. </li></ul><ul><ul><li>Covers all address elements, attributes, and classes. </li></ul></ul><ul><ul><li>Tests of address location relative to Address Reference System and known features </li></ul></ul><ul><ul><ul><li>Tests address data relative to local business rules </li></ul></ul></ul><ul><ul><ul><li>Measure how well a given set of address records conforms to the standard. </li></ul></ul></ul><ul><ul><li>Each test specification includes the scope, measure, and procedure of the test, and a script in SQL pseudocode. </li></ul></ul>
  14. 14. Data Exchange <ul><li>Requires open, standardized format: </li></ul><ul><ul><li>XML Schema Document (XSD) and XML. </li></ul></ul><ul><ul><li>Protects data producers and consumers </li></ul></ul><ul><ul><li>Allows localizations, but provides standard form for exchange. </li></ul></ul><ul><li>XSD provides a data model, but not a database model. </li></ul><ul><ul><li>Organizational database requirements and relationships vary considerably. </li></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  15. 15. Implementing The Standard <ul><li>The standard does not require incorporation of every element and attribute. </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>The standard does not require parsing every address into its simplest elements, nor does it require creation of a complex address data base. </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>The standard does not require use of the address attributes, although some attributes are essential for most purposes. </li></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  16. 16. Why A Standard is Needed <ul><li>Addresses are primarily created and maintained locally. </li></ul><ul><li>Address data is often poorly understood, badly recorded, and not well documented. </li></ul><ul><li>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. </li></ul><ul><li>As states create state-wide address database, the task of standardization and quality assurance becomes enormous. Standards help organize and simplify this process. </li></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  17. 17. Benefits of Implementing the Address Standard <ul><li>The standard supports the full range of address data needs, at all levels of government and in the private sector. </li></ul><ul><ul><li>Address management </li></ul></ul><ul><ul><li>Government administration </li></ul></ul><ul><ul><li>Emergency response </li></ul></ul><ul><ul><li>Postal delivery </li></ul></ul><ul><ul><li>Data exchange and aggregation </li></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
  18. 18. Why Should You Implement the Standard? <ul><li>It supports a comprehensive view of addresses that responds to needs for organization, quality, documentation, and exchange of address information. </li></ul><ul><ul><li>Broad participation provided information about differing address practices throughout the U.S. </li></ul></ul><ul><ul><li>Testing of the standard in real situations insured its usefulness and viability. </li></ul></ul><ul><li>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. </li></ul><ul><ul><li>Improved efficiency and economy: saves time, money and lives.b </li></ul></ul>NATIONAL STATES GEOGRAPHIC INFORMATION COUNCIL
