  1. 10 June 2014 Coordination Group Meeting Federal Geodetic Control SubcommitteeUpdate to Coordination Group Juliana Blackwell Subcommittee Chair Director, National Geodetic Survey Juliana.Blackwell@noaa.gov [16 May 2014]

  2. Introduction This subcommittee coordinates geodetic data-related activities among 23 Federal and non-Federal agencies and will report its activities to FGDC. Membership: http://www.fgdc.gov/participation/working-groups-subcommittees/fgcs/directory

  3. Geodetic Control Theme - Data Sets

  4. Recent Meetings • The subcommittee met on 13 January 2014 • The topics discussed at this meeting include: • Standardizing terminology: share, submit, publish, datasheet • Standards, specifications, and guidelines document updates • Changes to the National Flood Insurance program and associated elevation needs • Some of the outcomes arising from this meeting include: • Larry Hothem gave us a briefing on international standards activities • We documented our rationale for the selection of geodetic control theme datasets • Began to execute our plan to update standards documents

  5. Recent Developments/Projects • Geopotential Datum • GRAV-D: ~35% done • Geoid Slope Validation Survey in Iowa underway. GRAV-D status, May 2014 Green: AvailableBlue: Data being processedOrange: Data collection underwayWhite: Planned for data collection


  6. Recent Developments/Projects • FGDC Geospatial Positioning Accuracy Standards suite • NGS is updating two of the 5 parts • Part 1: reporting methodology • Part 2: standards for geodetic networks • To ensure consistency among the parts, we may have some input to Part 3 (National Standard for Spatial Data Accuracy) too. • Who should we work with if we have updates to Part 3, which is maintained by the USGS?

  7. Next Meeting • 24 July 2014 in Silver Spring, MD and via phone and Web • Some of the topics to be discussed at the next meeting include: • Photo-identifiable control points • ISO registry of geodetic codes and parameters

  8. Next Steps • In the coming months, the FGCS plans to: • Continue to prepare for the new geometric and geopotentialdatums. • Execute our plan to update standards documents.
