Fundamental Science Practices

USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.

Learn More

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.

Gravity map of the Nabesna Quadrangle, Alaska

The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of the gravity map are not easily explained by the map geology,

Index of Mariner 9 Albedo mapping pictures of Mars

This photoindex shows locations of the Mariner 9 pictures that are the primary source materials for the albedo marking, overlays in the U.S. Geological Survey's "Atlas of Mars." All pictures were taken by the "A" camera. The individual pictures were selected to provide complete coverage of the planet at the smallest scales possible with a minimum of overlap. They thus provide the most compact data

Index of Mariner 9 mapping pictures of Mars

This photoindex shows nominal locations of the set of Mariner 9 pictures taken by the "A" camera that are the primary source materials for the 1:5,000,000 Mars maps. These pictures were selected because they have the highest resolution of any set with contiguous coverage of the planet. Most or the pictures were token according to sequences designed for mapping by the Mariner 9 imaging team.The fra

Lakes in the greater Denver area, Front Range urban corridor, Colorado

The many lakes in Colorado's semiarid Front Range Urban Corridor have an especially high value. In the past they were used primarily to store water for irrigation and domestic uses. Some were used for recreation. Today, rapid suburban development in the Front Range Urban Corridor is accompanied by a shift of the principal use of many lakes to recreation and to centers of real estate developments.

Land use and land cover, 1972, Kentucky River area development district (KRADD)

This map is a demonstration product of experiments in land use and land cover mapping using remote sensor data.  The map is a joint effort of the U.S. Geological Survey's Land Use Data and Analysis (LUDA) program and the Appalachian Regional Commission.  It is part of a continuing USGS Land Information and Analysis Office demonstration of multi-discipline earth science contributions to the further
