GIS Data
USGS is a primary source of geographic information system (GIS) data. Our data and information is presented in spatial and geographic formats, including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more.
CoSMoS Implementation versions
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future SLR scenarios, as well as long-term shoreline change and cliff retreat. Several versions of CoSMoS have been implemented for areas of the California coast.

Anza Hydrologic Data
A portal for easy access to USGS data collected during hydrogeologic research projects in Anza Valley, CA
Anza Valley Land Use (1934 - 2005)
Compares Anza Valley, CA land use data within the USGS study boundaries for 5 time periods between 1934 and 2005.
Hydrologic Unit Maps
The U.S. is sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. Each unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on its classification. This site provides information and data for current and historical hydrologic units, names, and numbers.
U.S. Landslide Inventory
A web-based interactive map with a consistent set of landslide data. The searchable map includes contributions from many local, state, and federal agencies and provides links to the original digital inventory files for further information (wherever available).
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.
Western United States Geothermal Favorability
This map shows identified medium and high temperature geothermal systems and relative favorability for additional systems in the western United States.
Flood Inundation Mapper - Pennsylvania
USGS Flood Inundation Mapper Web Application
NY WSC Go2 Mapper
Interactive web mapping application used to display Go2 warning messages and field personnel locations. The Go2 system is used by USGS staff to monitor the maintenance of USGS gages.
Western Lake Erie Basin (WLEB)
Western Lake Erie Basin (WLEB) projects map depicts the sites and watersheds, as well as the data for each site through the interactive map.
USGS Streamflow and water-quality data including nutrient and sediment concentrations and daily, monthly, and annual loads are available on NWISWeb.
Principal Aquifers of the United States
A principal aquifer is defined as a regionally extensive aquifer or aquifer system that has the potential to be used as a source of potable water. This site provides downloadable maps (Ground Water Atlas of the United States, 2003) and spatial data (National Atlas, 2014) for the principal aquifers and aquifers of alluvial and glacial origin of the U.S.
