Taught by:
Claire DeVaughan
As one of the cornerstones of the U.S. Geological Survey's National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The geographic information available from The National Map includes elevation data, hydrography, land cover, geographic names, aerial photography, boundaries, transportation, and structures. This workshop will provide introductory information to The National Map and the variety of products and services it provides. Students will work with a variety of web-based applications to become familiar with the eight layers of The National Map, and learn about products, services, and data access. The latter part of the session will provide more specific information on features of the National Hydrography Dataset (NHD), the hydrography layer of The National Map, which serves as an authoritative geospatial dataset that maps and models the surface water of the United States.
