The USGS Topo Large service from The National Map (TNM) is a dynamic topographic base map service that combines the best available data (Boundaries, Elevation, Geographic Names, Hydrography, Land Cover, Structures, Transportation, and other themes) that make up The National Map. Contours generated for the US Topo product are visible along with other data at scales of 1:13,500 and larger. This product is designed to provide a seamless view of the data in a geographic information system (GIS) accessible format, closely resembling The National Map US Topo GeoPDF product at large scales.
USGS Imagery Topo is a topographic tile cache base map with orthoimagery as a backdrop, and combines the most current data (Boundaries, Names, Transportation, Elevation, Hydrography, and other themes) that make up The National Map. Contours generated for the US Topo product are included and are visible along with other data to the 1:18,000 zoom scale. This product is designed to provide a seamless view of the data, closely resembling The National Map's US Topo (GeoPDF) product at large scales, in a GIS accessible format. Orthoimagery data are typically high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a map. Digital orthoimage resolution...
U.S. Geological Survey, Department of the Interior - The annual Geographic Names acquisition plan is to collect geographic name data over the United States and its territories through the Board on Geographic Names processes. The U.S. Board on Geographic Names is a Federal body created in 1890 and established in its present form by Public Law in 1947 to maintain uniform geographic name usage throughout the Federal Government. The Board comprises representatives of Federal agencies concerned with geographic information, population, ecology, and management of public lands. Sharing its responsibilities with the Secretary of the Interior, the Board promulgates official geographic feature names with locative attributes...
The USGS Governmental Unit Boundaries service from The National Map (TNM) represents major civil areas for the Nation, including States or Territories, counties (or equivalents), Federal and Native American areas, congressional districts, minor civil divisions, incorporated places (such as cities and towns), and unincorporated places. Boundaries data are useful for understanding the extent of jurisdictional or administrative areas for a wide range of applications, including mapping or managing resources, and responding to natural disasters. Boundaries data also include extents of forest, grassland, park, wilderness, wildlife, and other reserve areas useful for recreational activities, such as hiking and backpacking....

U.S. Geological Survey, Department of the Interior - The annual US Topo acquisition plan is to collect topographic map data in the form of US Topo GeoPDF maps over the United States and its territories on a 3-year revision cycle. The FY14 acquisition plan currently anticipates production of 18,500 (or more) US Topo maps this year. Interested parties who wish to become a data acquisition partner with the USGS in FY14 or in future years should contact a USGS Geospatial Liaison - http://liaisons.usgs.gov/geospatial/documents/TNM_Partnership_User_ContactList.pdf.

USGS Hydro-NHD is a tile cache base map that combines hydrography data in The National Map from the National Hydrography Dataset (NHD) along with the Watershed Boundary Dataset (WBD). The NHD is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information...
