FGDC Standards • Standards organizations • Federal guidance on standards • Why use standards? • Recognition of non-Federally authored standards • Geospatial One-Stop
Standards Organizations • ISO, The International Standards Organization • ANSI, American National Standards Institute • INCITS • INSITS-L1 • FGDC, Federal Geographic Data Committee
Federal Standards Guidance and the FGDC • Executive Order 12906 (April 1994) • OMB Circular A-16 • OMB Circular A-119 • OMB Circular A-11 • OMB Circular A-130
Why use Standards • Facilitate data sharing • Increase interoperability among automated geospatial information systems.
Non-Federal Standards • Standards developed by other organizations • FGDC proposed policy on endorsement or recommendation of non-Federal standards Two levels of FGDC recognition • Endorsement – mandatory for use • Recommendation – the non-federal standard is recognized as a useful standard, but is not deemed to be of such broad applicability that its use should be mandatory.
Geospatial One-Stop • Accelerates implementation of the NSDI, making geospatial information access easier, faster, and cheaper for all levels of government and public • Increases federal agency accountability for the stewardship and sharing of geospatial resources. • Intergovernmental Board of Directors provides guidance to the project; includes Federal and non-federal.
Geospatial One-StopProject Modules • Establish integrated Data Content Standards for commonly used data themes. • Use metadata to inventory, document and publish Framework data holdings in NSDI Clearinghouse. • Publish metadata for planned data acquisition and update for Framework data in NSDI Clearinghouse (geospatial data marketplace). • Prototype and deploy enhanced data access and web mapping services for Federal Framework data. • Establish a Federal Portal (One-Stop) as a logical extension to the NSDI Clearinghouse Network.

Content Standards • Cadastral Data Content Standard • Content Standard for Digital Orthoimagery • Content Standard for Remote Sensing Swath Data • Utilities Data Content Standard • Content Standard for Digital Geospatial Metadata
Discussion In your experiences as first responders consider how the following would impact your ability to act. • Varying levels of content • Varying classification systems
Metadata • The value of metadata • Data preservation • Extending project dollar/efficient use of funds • Data access
Content Standard for Digital Geospatial Metadata • Biological Data Profile • Metadata Profile for Shoreline Data • Extension for Remote Sensing Metadata
Who What Where Why When How Sources Methods Processes Attributes Projection Distribution Minimal vs. Detailed Metadata
Discussion In your experiences as first responders consider how the following would impact your ability to act. • Varying scales • Attributes lack of/varying • Temporal aspects • Other data issues
Metadata in the Future • ISO • Why a new standard • When • Migrating to the new standard
