2006 Indiana GIS Conference March 8, 2006 - Indianapolis Charles Hickman USGS National Geospatial Program Office
Disciplines of the U.S. Geological Survey • Geology (GD) • Water Resources (WRD) • Biological Resources (BRD) • Geography and Mapping (National Geospatial Program Office)
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.
National Hydrography Dataset • Stream network – streams, canals, other paths: 80% • Water bodies – lakes, reservoirs, other areas: 14% • Landmarks – dams, bridges, geysers, other items: 6%
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
Seamless Data • Not quad based • Online access • GIS ready • Variable-resolution • Feature-level metadata • Update features as needed by transactions • Versions • Stable identifiers
Geometry Relationships Feature Features Feature Blacksmith Creek Attributes Main Components • Features • Reaches • Flow relationships • Geographic names • Level paths • Coordinates and measures • Metadata
NHD – Applications and Related Programs • How is NHD used? • Support inventory, analysis, visualization, mapping, modeling . . . • Water quality, flooding, fish . . .
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
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
