Water Information Status Report: Integration of Spatial Water Datasets

This report discusses the integration of key spatial water datasets, including the National Elevation Dataset and National Hydrography Dataset, to create a surface water geospatial framework. The Subcommittee on Spatial Water Data's role is to encourage, facilitate, and review the progress of this integration. The report also provides information on the subcommittee's efforts to develop a reference set of watersheds and the verification process for the Watershed Boundary Dataset. Funding, working groups, and problematic states are discussed, along with upcoming meetings and the goals of the subcommittee. The report also touches on the Geospatial One-Stop initiative and its focus on developing framework data content standards.

  1. Advisory Committee on Water Information Status report: Subcommittee on Spatial Water Data Herndon, VA September 10, 2003

  2. “surface water geospatial framework” Integration of key Spatial Water Datasets National Elevation Dataset National Hydrography Dataset COMPLETE 30meter COMPLETE 1:100K IN PROGRESS 1:24K IN PROGRESS 1:24K NED-Hydrology Watershed Boundary Dataset IN PROGRESS 1:24K COMPLETE 30meter

  3. Subcommittee’s role • encourage • facilitate • review

  4. 1/3 arc second NED

  5. Interagency Development of a Reference Set of Watersheds for the United StatesWBD

  6. Hydrologic Units Where are we? 2-digit= 1st level = 22 regions 4-digit= 2nd level = 222 subregions 6-digit= 3rd level = 789 accounting 8-digit= 4th level = 2223 cataloging new! WBD 10-digit= 5th level = ~22,000 watersheds 12-digit= 6th level = ~160,000 subwatersheds

  7. Submittal Projections WBD VERIFICATION PROCESS

  8. Funded Working Groups Salt Lake City USGS Ft. Worth NRCS Sacramento BOR Philadelphia EPA Atlanta USGS EROS Data Center USGS

  9. Problematic States Arizona:NRCS,USFS and BLM do not recognize need for 6th Level Delineations. Idaho: Lack of in-kind funding. North Dakota:Inefficient process, minimal funding. Minnesota: Too much detail is being added well beyond the needs of the WBD. Estimated completion date at the current rate is 15 years. Plenty of funding, but have not been amenable to changing process. Louisiana:No local support. New York:Inefficient process, lack of coordination. New Jersey:Reluctant to modify existing dataset

  10. WBD MEETINGS Austin

  11. FY04 Meetings Planned Portland, OR : Evaluation of NV, OR, ID, WA Syracuse, NY : Evaluation of NY, VT, NJ, PA Charleston, WV : Evaluation of WV, OH, VA Columbia, SC : Wrap up of SC dataset Needed Minneapolis, MN Phoenix, AZ Madison, WI New Orleans, LA

  12. Meeting Detail

  13. Subcommittee on Spatial Water Data Coastal Watersheds Work Group Hydro Standard Work Group Guidelines Work Group National Hydrography Framework Standard FGDC HUC unified Guideline

  14. National Hydrography Framework Standard • Develop formal Content Standard for Hydrography. • describe a general model (a data dictionary, definitions, relationships) • application-independent, • supportsinternational standards • facilitates the exchange of data.

  15. EGOV Initiative Geospatial One-Stop • Key points • Develop and implement Framework Data content standards • Elevation • Orthoimagery • Hydrography • Administrative Boundaries • Transportation Networks • Cadastral • Geodetic Control • Establish comprehensive Federal Portal • Director Hank Garie, USGS Co-chairman, Scott Cameron, DOI

  17. NHD Partnerships

  18. “high-res”NHD COMPLETE FY06

  19. Density differences Paper map

  20. NHD Problem: Drainage Density Artifacts reference paper map

  21. Subcommittee on Spatial Water Data FY04 THEME: “interoperable”

  22. Tying points to streams

  23. Geospatial One Stop Purpose of the project: • Making it: • Easier • Faster • Less expensive For all levels of government and the public to access geospatial information.

  24. Federal Integration Services Support Government Business Support Decision Making Homeland Security Recreation One Stop Disaster Management Smart Growth Citizen Services Other E-gov Initiatives Watershed Management Counties States Cities Tribes Academia GOS Portal • User Community • Data Searches • Map Services • Visualization Private

  25. Request for “Data Category Managers”
