Federal Geodetic Control Subcommittee Update to Coordination Group

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.
