USGS Trail Data Portal

Do we have your trails? The USGS Trail Data Portal allows land managers to submit their trail data for potential inclusion into the nationwide trails dataset. The dataset must have at least 50 miles of trails, be in the public domain, and pass a data review to be included. Email trails@usgs.gov for more information.

TRAILS – Trail Routing, Analysis, and Information Linkage System

TRAILS – Trail Routing, Analysis, and Information Linkage System is a trail planning and collaboration tool that utilizes geospatial analysis to determine potential routes for new trail connections or to reroute an existing trail.  

USGS Trails Explorer

The USGS Trails Explorer visualizes the current distribution of aggerated trails.  

Coastal Salinity Index

The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including sea level, tides, winds, precipitation, streamflow, and tropical storms.

Sparrow Modeling North Carolina Watersheds Mapper

The USGS developed the SPARROW (SPAtially Referenced Regressions On Watershed attributes) modeling framework to relate water-quality monitoring data to upstream nutrient and sediment sources and watershed characteristics. The mapper can be used to evaluate alternative hypotheses about the relative importance of various pollutant sources.

North Carolina Rainfall Map

Map of North Carolina rain gages with National Weather Service precipitation overlays.

Georgia Water Use

The U.S. Geological Survey (USGS) South Atlantic Water Science Center and the Environmental Protection Division of the Georgia Department of Natural Resources have been collecting and compiling water-use information in Georgia since 1980 as part of an ongoing cooperative agreement.

Groundwater Conditions of Georgia

The Groundwater Conditions of Georgia web tool has interactive maps and graphs, that calculate water level trends over time. The application is a continuation of a series of reports begun in 1978.  

U.S. Geological Survey National Produced Waters Geochemical Database (ver. 3.0, December 2023) Viewer

The U.S. Geological Survey National Produced Waters Geochemical Database Viewer (ver. 3.0) provides access to an updated compilation of geochemical and related information for water from oil and gas wells in the United States. The information includes identification and location information, well descriptions, dates, rock properties, physical properties of the water, organic chemistry and more.
