Core Science Systems
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.
A web-based map viewer allowing users to search, view and download species occurrence data from BISON.
The Protected Areas Database of the United States (PAD-US) Viewer provides a spatially explicit inventory that lets any user – from the general public to professional land managers – explore the protected areas network anywhere in the United States and allows them to easily use this inventory in conservation, land management, planning, recreation and other uses.
The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program. The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.
The GAP Species Viewer provides nation-wide range maps and distribution models for amphibians, birds, mammals, and reptiles occurring in the continental U.S., Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. These kinds of maps and data are fundamental to assessing patterns of species richness and planning for the management of the nation's biological diversity.
The viewer allows exploring the condition of stream and coastal habitats across the country at various spatial scales, reported in Through a Fish's Eye: The Status of Fish Habitats in the United States 2010. It offers a variety of base maps and provides one-click access to more detailed information on landscape disturbances and habitat scores for individual stream catchments.
The 3DEP products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
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.
This is the primary search and download application for USGS topographic maps and base-layer GIS data. The same topographic maps are also downloadable through other interfaces.
USGS topographic maps originally published on paper in the period 1884-2006 have been scanned and published as PDF documents. This collection is of topographic quadrangle maps with scales between 1:10,000 and 1:250,000. These historic documents are downloadable free of charge through several interfaces.
The National Geospatial Program satisfies the needs of customers by providing geospatial products and services that customers incorporate into their decisionmaking and operational activities.
