This is an interactive version of the Alaska geologic map database which allows a user to view and access many features of the database and map through a standard web browser. In other words, there is no need for or knowledge of specialized GIS software.

The USGS Global Visualization Viewer (GloVis) is an online search and order tool for selected remote sensing data.

USGS online mapper for water-table altitude, and potentiometric surface of the Magothy, Jameco, Lloyd, and North Shore aquifers on Long Island, NY, in 2010.

The Hazard Exposure and Reporting Analytics (HERA) website helps communities understand how natural hazards could impact their land, people, infrastructure, and livelihoods. HERA provides tools and data to help communities as they plan and prepare for natural hazards.

Help scientists at the U.S. Geological Survey annotate aerial photographs with keyword tags to identify changes to the coast after extreme storms.

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.

The Virginia Water-Monitoring-Sites Mapper is an interactive map of Virginia water monitoring-site locations from the USGS Water Data for the Nation. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

The West Virginia Water-Monitoring-Sites Mapper is an interactive map of West Virginia water monitoring-site locations from the USGS Water Data for the Nation. It provides access to surface water, groundwater, and water quality monitoring data for active sites.

USGS collects groundwater data at varying measurement frequencies to monitor the hydrologic conditions on Long Island, New York. Each year during April and May, the USGS conducts a synoptic survey of water levels to define the spatial distribution of the water table and potentiometric surfaces within the three main water-bearing units underlying Long Island.

On July 11-12, 2016, severe thunderstorms hit northern Wisconsin, resulting in widespread flooding. Immediately following the flood, the USGS and the Bad River Band of the Lake Superior Tribe of Chippewa Indians began collecting evidence of peak flood levels. USGS scientists used these high-water marks, along with streamflow and lake level, to reconstruct the extent and depth of flood inundation.

MODFLOW is the USGS's three-dimensional (3D) finite-difference groundwater model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
