FGDC endorses the Geographic Information Framework Data Standard

The Federal Geographic Data Committee (FGDC) endorsed the Geographic Information Framework Data Standard in May 2008.

The Geographic Information Framework Data Standard establishes common requirements for data exchange for seven themes of geospatial data identified as framework data themes in OMB Circular A-16, Revised. Framework data themes are critical to the National Spatial Data Infrastructure (NSDI), as they are fundamental to many different Geographic Information Systems (GIS) applications. The seven NSDI Framework data themes are:

  1. Cadastral data
  2. Digital orthoimagery
  3. Elevation
  4. Geodetic control
  5. Governmental Unit Boundaries
  6. Hydrography
  7. Transportation

The Geographic Information Framework Data Standard specifies a minimal level of data content for each theme, which data producers, consumers, and vendors are expected to use for the interchange of framework data, including through Web services. The standard includes a base document and parts that correspond to the NSDI Framework data themes. The transportation part includes subparts that correspond to different modes of transportation: airport facilities; rail; roads; transit; and waterways.

Each part includes an integrated application schema expressed in Unified Modeling Language (UML), which was developed through the Object Management Group (OMG). The application schema specifies, as appropriate, the feature types, attribute types, attribute domain, feature relationships, spatial representation, data organization, and metadata that define the information content of a data set. XML Metadata Interchange (XMI), another specification developed by OMG, is used to exchange UML models between various modeling software packages.

The Geographic Information Framework Data Standard does not specify a single structure for the interchange of data. However, XMI data can be converted into Geography Markup Language (GML).  GML was developed by the Open Geospatial Consortium and approved as ISO 19136:2007, Geographic information - Geography Markup Language.

The Geographic Information Framework Data Standard was initially developed through the Geospatial One-Stop e-Government initiative; however, the FGDC assumed leadership for continued standards activities.

As the Geographic Information Framework Data Standard was developed using public funds, the U.S. Government will be free to publish and distribute its contents to the public, as provided through the Freedom of Information Act (FOIA), Part 5 United States Code, Section 552, as amended by Public Law No. 104-231, “Electronic Freedom of Information Act Amendments of 1996”.
