The United States Geological Survey's (USGS) online interactive map tool provides access to a visual GIS database of geological data from Georgia, including access to publications and the ability to download GIS data.

The interactive map allows users to view surface geology and click anywhere on the map to access scientific data and source publications.

The Florida Geological Survey provides a huge amount of information on Florida's geology and natural resources in interactive map form, including:

The Connecticut Geological Survey's (CGS) map of surficial aquifer potential shows the areas with high potential for groundwater supply based on the thickness of coarse-grained deposits. Colors on the map indicate the thickness of coarse-grained deposits and the thickness of fine-grained deposits where they occur over coarse-grained sediments.

The U.S. Geological Survey's (USGS) Mineral Resources Program's interactive Geologic Map of U.S. States provides a large amount of information on geology, natural resources, and environmental data for every U.S. state, including:

• Surface and bedrock geology
• Mineral resources
• Geochemical and geophysical data
• Water monitoring sites
• Partial soil and land use data

All of the maps are also available as Google Earth files that can be downloaded and used on personal computers and mobile devices.

The Arizona Geological Survey's Geologic Map Database for Aggregate Resource Assessment in the Phoenix, Arizona Metropolitan Area and Surrounding Regions provides valuable information for resource development and land use planning. The database is an integrated product with shapefiles and other digital data. The primary purpose of this database is to depict geologic units that have been and are being exploited for aggregate resources in a uniform and fairly simple manner. 

The U.S. Department of Energy's interactive map of the energy sector's climatic vulnerabilities allows users to explore how climatic events have impacted the energy sector over recent years. You can view how impacts due to increasing temperatures, decreased water availability, and increasing storms, floods, and sea level rise have adversely affected energy resource development, distribution, production, and transmission.

The U.S. Geological Survey provides a website of visualizations that show how California's extreme drought in the early-mid 2010s progressed through the early-mid part of the decade and then was relieved with significant rain and snowfall in 2016-2017. Visualizations of the extent and severity of drought, change in reservoir volumes, and streamflow compared to historic rates are all available on the website, which you scroll through to see different features.

The U.S. Geological Survey (USGS) Volcano Hazards Program's visualization shows the projected ash cloud for three differently-sized, hypothetical eruptions of Mount St. Helens. The visualizations depict a simulation of the spread of volcanic ash, based on a combination of wind data from the National Oceanic and Atmospheric Administration (NOAA) and volcanologist-derived eruption size parameters.

The California Geological Survey's interactive map allows users to identify the location and classification of faults throughout California. Information available includes the age of the most recent activity on each fault segment, surface rupture areas, and whether or not the faults are visible at the surface.
