Circulars are instructions or information issued by the U.S. Office of Management and Budget (OMB) to Federal agencies. Two OMB circulars in particular guide the FGDC.
OMB Circular A-16, Coordination of Geographic Information, and Related Spatial Data Activities
This Circular provides direction for federal agencies that produce, maintain or use spatial data either directly or indirectly in the fulfillment of their mission. This Circular establishes a coordinated approach to electronically develop the National Spatial Data Infrastructure and establishes the Federal Geographic Data Committee (FGDC).
The Circular has been revised from the 1990 version to reflect changes in technology, further describe the components of the National Spatial Data Infrastructure (NSDI), and assign agency roles and responsibilities for development of the NSDI. The revised Circular names the Deputy Director for Management of OMB as Vice-Chair of the Federal Geographic Data Committee.
OMB Circular A-130, Management of Federal Information Resources
This Circular establishes policy for the management of Federal information resources. OMB includes procedural and analytic guidelines for implementing specific aspects of these policies as appendices.
OMB Circular A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities
This Circular establishes policies on Federal use and development of voluntary consensus standards and on conformity assessment activities.
