The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types.

This data represents the map extent for current and historical USGS topographic maps for the United States and Territories, including 1 X 2 Degree, 1 X 1 Degree, 30 X 60 Minute, 15 X 15 Minute, 7.5 X 7.5 Minute, and 3.75 X 3.75 Minute. The grid was generated using ESRI ArcInfo GIS software.

This is a 1-meter resolution digital surface model (DSM) derived from commercial electro-optical satellite imagery. Contributing imaging sensors include WorldView-1, WorldView-2, WorldView-3, and GeoEye-1. A digital surface model (DSM) is a 3D representation of the Earth’s surface height, including any natural or built features located on it, such as the tops of buildings, trees and vegetation. This “top of surface” elevation dataset was produced by the National Geospatial-Intelligence Agency (NGA) with the support of the GeoData Cooperative. The GeoData Cooperative is a Department of Defense mission-driven collaboration between industry, academia, and the U.S. Government to enable access to current, accurate, and...

This coverage includes arcs, polygons and polygon labels that describe U.S. Geological Survey defined geologic provinces of the Australia and New Zealand area (Australia, Fiji, New Zealand, Tonga and Vanuatu; and parts of Indonesia, Papua New Guinea and Solomon Islands). Each province has a set of geologic characteristics distinguishing it from surrounding provinces. These characteristics may include the dominant lithologies, the age of the strata, and the structural style. Some provinces include multiple genetically-related basins. Offshore province boundaries are defined by the 2000 meter bathymetric contour.
