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.

A rapid approach for automated comparison of independently derived stream networks

This paper presents an improved coefficient of line correspondence (CLC) metric for automatically assessing the similarity of two different sets of linear features. Elevation-derived channels at 1:24,000 scale (24K) are generated from a weighted flow-accumulation model and compared to 24K National Hydrography Dataset (NHD) flowlines. The CLC process conflates two vector datasets through a raster l

National hydrography dataset--linear referencing

Geospatial data normally have a certain set of standard attributes, such as an identification number, the type of feature, and name of the feature. These standard attributes are typically embedded into the default attribute table, which is directly linked to the geospatial features. However, it is impractical to embed too much information because it can create a complex, inflexible, and hard to ma
