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. - Multimedia

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 lNational 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 - News
