Development and Implementation of FGDC Standards Presented by Julie Binder Maitra Federal Geographic Data Committee (FGDC) To Second Earth Science Data Systems Working Group (ESDSWG) Meeting October 19, 2004

Introduction to the FGDC –Federal guidance on the National Spatial Data Infrastructure (NSDI) –Components of the NSDI –FGDC Organization FGDC Standards Development Process FGDC Standards Accomplishments Non-Federal standards Framework Data Standards Development and Implementation of FGDC Standards

Federal guidance on NSDI Executive Order (April 1994) establishes the National Spatial Data Infrastructure (NSDI) as “the technology, policies, standards, and human resources necessary to acquire, process, store, distribute, and improve utilization of geospatial data.” OMB Circular A-16 (Revised August 2002) incorporates EO and affirms the NSDI. establishes the FGDC as the interagency coordinating body for NSDI-related activities

The FGDC Standards Process is: –Structured –Iterative –Well-documented The FGDC develops standards for geospatial data only when there are no non-Federally authored standards that fulfill agency missions and program needs The FGDC standards development process is modeled after ISO and ANSI standards processes FGDC Standards Process

FGDC Standards Process The FGDC Standards Process is iterative

FGDC Standards Process The FGDC Standards Process is documented in: FGDC Standards Reference Model, 13 supporting FGDC Directives,

FGDC Standards Accomplishments 20 FGDC Endorsed Standards –First standard endorsed in 1995: Content Standard for Digital Geospatial Metadata (version 2.0), FGDC-STD –Latest standard endorsed in August 2002: Content Standard for Digital Geospatial Metadata: Extensions for Remote Sensing Metadata, FGDC-STD –Other endorsed standards include: Spatial Data Transfer Standard (SDTS) & profiles Geospatial Positioning Accuracy Standards Various thematic data standards 19 other Standards in various stages of the FGDC Standards Process

ISO Technical Committee 211, Geographic information/Geomatics, is focused on abstract specifications, design framework, and international political consensus Open Geospatial Consortium specializes in extending the abstract model into implementation specifications FGDC and INCITS Technical Committee L1, GIS, support the development of thematic data content standards FGDC participation in non-Federal standards organizations

Development of Framework Data Standards  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  Use ISO series of geographic information standards developed by ISO Technical Committee 211, Geographic information/Geomatics, ANSI standards, and FGDC standards to develop Framework data standards  Apply ISO General Feature Model to define feature types  Provide UML modeling support  Provide documentation of feature types in data dictionary  Map UML data models to XML/Geography Markup Language schema documents

Map UML Models to XML/GML Schemas  UML data models in.xmi format 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  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.

Resources  FGDC,  Framework Standard Registered Review site,  INCITS Technical Committee L1,  ISO Technical Committee 211,  Open Geospatial Consortium (formerly OpenGIS Consortium),  Mapping an ISO UML Application Schema to a GML Application Schema, instruments.de/ugas  Object Management Group, (UML specification and.xmi format)  W3C, (XML specification)
