USGS is a primary source of Geographic Information Systems (GIS) Data. Our data and information is presented both spatially and geographically including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more. Start exploring by topic below.
This mapper displays SPARROW nutrient load and yield data specifically for U.S. tributaries to the Great Lakes. The results are based on the SPARROW models developed for the Great Lakes, Ohio, Upper Mississippi, Red River Basins (MRB3). Modeling results can be exported as an Excel spreadsheet or a geospatial dataset.
The mapper displays SPARROW nutrient load and yield data and the importance of various nutrient sources for the MARB, given nutrient inputs similar to 2002. Rankings can be shown by major watershed, state, HUC8, tributary, and catchment. Nutrient data can be explored using maps and interactive graphs and tables. Modeling results can be exported as an Excel spreadsheet or a geospatial dataset...
This mapper displays SPARROW nutrient load and yield data specifically for the Yellowstone River. The results are based on the SPARROW models developed for the Mississippi/Atchafalaya River Basin (MARB). Modeling results can be exported as an Excel spreadsheet or a geospatial dataset.
The SPARROW Decision Support System displays model predictions of water-quality conditions and sources by stream reach and catchment, tracks the transport to downstream receiving waters, and can be used to evaluate management source-reduction scenarios. Models currently available include national nitrogen, phosphorus, and suspended sediment models...
The Bad River Groundwater Model Mapper accompanies the report "Groundwater-Surface Water Interactions in the Bad River Watershed, Wisconsin". The mapper displays model inputs such as aquifer recharge and hydraulic conductivity; outputs including water-table elevations, groundwater-flow directions, and stream baseflows; and the results of an analysis evaluating potential monitoring well...
This tool provides access to maps of watershed nutrient contributions to the Nation's Estuaries.
U.S. Geological Survey scientists developed a dataset of 2006 and 2011 land-use and land-cover (LULC) information for selected 100-km2sample blocks within 29 U.S. Environmental Protection Agency (EPA) Level III ecoregions across the conterminous United States.
The U.S. National Geologic Map Database (NGMDB) serves as the authoritative, comprehensive resource for information about paper and digital geoscience maps and reports on the Nation's geology and stratigraphy, by all publishers.
The interactive map with photo viewer application allows users to navigate to, select, and explore attributes, photos, and documents associated with Campsite and Sandbar features of the Colorado River channel between Glen Canyon Dam and Lake Mead.
Data on 6,767 flood events at 1,597 individual sites throughout Colorado were compiled to generate the flood database. The data sources of flood information are indirect discharge measurements that were stored in U.S. Geological Survey offices (water years 1867–2011), flood data from indirect discharge measurements referenced in U.S. Geological Survey reports.
This is a new tool for understanding and communicating risks. The activities include the development of risk models and approaches to improve the situational awareness of communities and industries to natural hazards and reduce the uncertainty of those risk assessments.
