The United States Geological Survey (USGS) Land Cover Trends field photography collection is 33,000 ground-referenced photos at a national-scale. The photos initially served as a research tool to aid in Landsat-derived land-use/land-cover (LULC) change analyses and assessments between 1999 and 2009.

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

This web mapping application allows users to make comparisons between national scale environmental datasets and Bacillus species and Bacillus anthracis detection results. The datasets include soil physical, chemical, and mineralogical data, current and historical climate data, landcover, and biological surveys.

While some instrument teams provide science-ready versions of their data, many other archives must first be processed by the individual researcher. POW provides users with calibrated cartographic images that can be used for geologic mapping, analysis in a Geographic Image System (GIS), change detection, merging of dissimilar instrument images, and use in a host of other scientific applications.

The goals for this website are to catalog completed geologic maps and to help track the progress of currently funded maps. If you would like to propose for a mapping investigation, check the appropriate planetary body in the map index or refer to the various mapping pages (linked under Maps above) to see which geologic maps may have already been published or are currently in progress. 

Planetary nomenclature is used to uniquely identify a feature on the surface of a planet or satellite so that the feature can be easily located, described, and discussed.

See the FAQ for more information on common questions.

For general inquiries regarding planetary nomenclature or the Gazetteer website, please contact Tenielle Gaither by emailing tgaither@usgs.gov.

PILOT (Planetary Image Locator Tool) is an online data portal used by planetary scientists and cartographers to search through the raw archives of the PDS Cartography and Imaging Science Node. It searches through a large catalog of visual, infrared and spectrometer camera images taken of planetary bodies in our solar system. For information on specific missions, please visit the Data Portal. 

Interactively explore assessment summary information for continuous (unconventional) assessments conducted at the USGS from 2000-2018. The assessment results data used to generate this visualization can be downloaded here in Excel Format.  These data represent all assessment results for Continuous Assessments only from 2000-2018.

The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.

To better identify the significant processes affecting our coastlines and how those processes create coastal change we have developed a Coupled Ocean – Atmosphere – Wave – Sediment Transport (COAWST) Modeling System, which is integrated by the Model Coupling Toolkit to exchange data fields between the ocean model ROMS, the atmosphere model WRF, the wave model SWAN, and the sedime

In cooperation with the City of Houston, USGS collects, processes, and interprets water-quality, streamflow, and reservoir water elevation and capacity data. These data are collected to better understand the effects of urbanization in Lake Houston, a drinking water reservoir in Houston, Texas. 

GWWebFlow is a browser-based groundwater model viewer designed to allow users to easily explore model inputs and outputs for published and approved USGS models.
