Science and Products
US Topo - the Current Generation of USGS Topographic Maps
US Topo maps are modeled on the familiar 7.5-minute, 1:24,000-scale quadrangle maps of the period 1947-1992, but are mass-produced from national GIS databases on a 3-year cycle.The maps are layered PDF documents with geospatial extensions. They are downloadable free of charge through several interfaces.
The National Hydrography Dataset (NHD)
The National Hydrography Dataset (NHD) represents surface waters of the United States including, rivers, streams, lakes, and coastal features. The Watershed Boundary Dataset (WBD) is comprised of hierarchical polygons called hydrologic units that represent surface area over which water drains to a point. Both datasets are updated by stewards and are available by subsets of the United States.
Hydrography Seminar Series - Session 9 (NHDPlus HR)
The USGS Hydrography Seminar Series shares success stories from users, provides information on the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), NHDPlus High Resolution (NHDPlus HR), and other related products, and provides a forum for users to learn more about hydrography-related topics. Seminar 9 is an overview of the NHDPlus HR.
