  1. 2006 Indiana GIS Conference March 8, 2006 - Indianapolis Charles Hickman USGS National Geospatial Program Office

  2. Disciplines of the U.S. Geological Survey • Geology (GD) • Water Resources (WRD) • Biological Resources (BRD) • Geography and Mapping (National Geospatial Program Office)

  3. National Hydrography Dataset A comprehensive set of digital spatial data that contains information about: • naturally occurring and constructed bodies of water • natural and artificial paths through which water flows • related hydrographic entities.

  4. National Hydrography Dataset • Stream network – streams, canals, other paths: 80% • Water bodies – lakes, reservoirs, other areas: 14% • Landmarks – dams, bridges, geysers, other items: 6%

  5. National Hydrography Dataset • National program • Combine hydro spatial data programs of • USGS DLG • EPA RF3 • USFS CFF • other national, state, and regional partners • Coordinate update efforts

  6. Seamless Data • Not quad based • Online access • GIS ready • Variable-resolution • Feature-level metadata • Update features as needed by transactions • Versions • Stable identifiers

  7. 100K NHD and 24K NHD

  8. Geometry Relationships Feature Features Feature Blacksmith Creek Attributes Main Components • Features • Reaches • Flow relationships • Geographic names • Level paths • Coordinates and measures • Metadata

  9. NHD – Applications and Related Programs • How is NHD used? • Support inventory, analysis, visualization, mapping, modeling . . . • Water quality, flooding, fish . . .

  10. NHD – Applications, Related Programs, and Tools (1) • RIT - Reach Indexing Tool for NHD - georeferencing surface water databases to NHD • BASINS - Better Assessment Science Integrating Point and Nonpoint Sources - integrated watershed environmental modeling • CWAEM - Clean Water Act Effects Model - basic water quality modeling and economic analysis • NAWQA - National Water-Quality Assessment Program • NLFWA - National Listing of Fish and Wildlife Advisories

  11. NHD – Applications, Related Programs, and Tools (2) • WATERS - EPA Water Assessment, Tracking & Environmental Results • Section 303d, Clean Water Act • TMDL - Total Maximum Daily Load • Section 305b, water quality assessment • STORET - data STOrage and RETrieval system - water quality data repository

  12. Analysis of Isolated Lakes in Michigan 135 / 332 lakes are connected to the 1:24,000 NHD 197 / 332 lakes are considered seepage lakes

  13. Prototype of Aquatic Invasive Species Habitat

  14. High Resoluton (24K) Status on April 7, 2002

  17. Related National Datasets • NED – National Elevation Dataset • EDNA – Elevation Derivatives for National Applications • NWBD – National Watershed Boundary Dataset • NLCD – National Land Cover Dataset • USGS plans for National Map

  18. National Elevation Dataset (NED)

  19. Elevation Derivatives forNational Applications (EDNA)[ Formerly National Elevation Dataset – Hydrologic Derivatives (NED-H) ]

  20. National Watershed Boundary Dataset (NWBD) • Integrated with NED and NHD

  21. Hydrologic Units

  22. National Land Cover Dataset (NLCD) • Urban • Farmland • Pasture • Orchard • Row crops • Water • Barren • Forest • …

  23. Homeland Security

  24. Indiana • IDNR • IDEM • USGS WRD & NMD • US Forest Service

  25. NHD Stewards • The NHD is a living dataset • Revision updates needed • Quality updates needed • Organizations closest to the hydrography • are most aware of ground truth • Such organizations should have • the opportunity to serve as stewards • The USGS will assist

  26. NHD Partnerships Local State Federal

  27. National Hydrography Dataset • National Database • Meets NSDI and FGDC Objectives • Technology Available • Data Standard Meeting Multiple User Needs • Future Applications Support • Feature Based Model • Framework for Additional Data • Flexible • Maintenance Mechanism

  28. Almost Done • Monthly NHD Newsletter • USGS Geodata Liaison for Indiana • Indiana NHD Workshop with Jeff Simley
