Getting to Know the National Hydrography Dataset (Full-Day)
Sunday, February 9, 2020 - 8:30 AM - 5:00 PM

Jane SchaferKramer, Geographic Data Specialist, California Department of Water Resources, Davis, CA
Drew Decker, U.S. Geological Survey, National Map Liaison, San Diego, CA
Carol Ostergren, US Geological Survey, Geographer, Santa Cruz, CA

The National Hydrography Dataset (NHD) is the mapping of the surface waters of the U.S. and the Watershed Boundary Dataset (WBD) represents drainage areas delineated to nest in a multi-level, hierarchical drainage system. They are integral parts of USGS’ National Map and serve as an authoritative common framework for users and organizations to tie into their own data. This course provides an opportunity to discover the information in these datasets and to get comfortable using them for planning, analysis, and general mapmaking, and introduces the ways the user community can get involved with stewardship of the data.

  • Gain familiarity with the background, the information contained within, and the current state of the NHD, WBD, and NHDPlus
  • Be comfortable using it in a GIS for mapping and analysis
  • Understand how to contribute to the improvement of the data

  • The data model and definitions of the features and tables in the NHD geodatabase
  • Tips for mapping and cartography with the NHD
  • Tracing flow connectivity on the geometric network
  • Linear referencing along the flowlines
  • Applications of the NHD and WBD
  • An introduction to NHDPlus and its applications
  • Keeping NHD updated: California stewardship and community participation

HANDS-ON: For the best experience please bring a laptop with ArcMap (any version, any license level) software and license; QGIS may be used if ArcMap is not available.

AUDIENCE: GIS users (cartographers, scientists, planners, engineers, mapping app developers, students, data analysts, and others) who would like to discover the information contained in the NHD, WBD, and NHDPlus and how to use them in ArcGIS for mapping and analysis.

PREREQUISITES: Beginner-level working knowledge of ArcGIS or QGIS
