Standards development approach l.jpg
Standards development approach

  • Develop standards through procedures established by the American National Standards Institute (ANSI) and InterNational Committee for Information Technology Standards (INCITS).

  • Bring together subject matter experts from all levels of government (Federal, State, and local), academia, and the private sector to develop data standards for Framework themes

  • Provide UML modeling support

  • Transform UML data models into XML/Geography Markup Language schema documents

Applying iso tc 211 standards to the development of framework data standards6 l.jpg
Applying ISO/TC 211 standards to the development of Framework Data Standards

Key ISO Standards:

  • ISO 19109, Geographic information - Rules for application schema

  • ISO 19115, Geographic information - Metadata

  • ISO 19123, Geographic information - Schema for coverage geometry and functions

  • ISO 19136, Geographic information – Geography Markup Language


Applying iso tc 211 standards to the development of framework data standards7 l.jpg
Applying ISO/TC 211 standards to the development of Framework Data Standards

Application of ISO 19109

  • Use General Feature Model to describe geographic features (applies to geodetic control, cadastral, hydrography, transportation, and government units boundaries themes)

  • Build Application schema in UML

Application of iso 19115 l.jpg
Application of ISO 19115

  • Framework Data Standards will be compliant with ISO 19115

  • Some elements listed as optional in ISO 19115 are mandatory for Framework Data Standards

    • examples: Metadata standard name, Metadata standard version, Dataset purpose, Dataset progress, Dataset maintenance and update frequency

  • ISO 19115 elements closely match elements in FGDC Content Standard for Digital Geospatial Metadata, FGDC-STD-001-1998 (version 2.0); therefore, data standards will be compliant with FGDC standard

    • FGDC standard lacks metadata elements for language and character set


Application of iso 19123 l.jpg
Application of ISO 19123

  • Application of ISO 19123 (for digital orthoimagery and elevation themes)

    • Digital orthoimagery adopts ISO 19123 classes such as CV_Coverage, CV_ContinuousQuadrilateralGridCoverage, CV_Grid, CV_GridValuesMatrix

    • Elevation standard models data as simple discrete coverages


Application of iso 1912313 l.jpg

The draft elevation standard models data as simple discrete coverages


Application of iso 19136 l.jpg
Application of ISO 19136

  • UML data models in .xmi format (defined by OMG) were transformed to XML/Geography Markup Language (GML) schemas through UGAS software tool

  • The XML/GML schema documents can be used to create, validate, and process geographic information with XML parsing and validation software.

  • Activity supported through Information Interoperability component of the Open Geospatial Consortium’s Open Web Services 2.0 Testbed


Status of framework data standards l.jpg
Status of Framework Data Standards

  • Standards project is registered as INCITS Project 1574-D, Geographic Information – Framework Data Content Standard

  • Objective is an American National Standard (ANS)

  • Standards initially developed through Geospatial One-Stop e-government initiative, but FGDC has assumed leadership for further development

  • Draft standards out for public review until October 30, 2004

  • The FGDC funded projects across the U.S. to serve and use Framework data over the web using the Open Geospatial Consortium’s Web Feature Service (WFS) specification.
