The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program.  The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.

The GAP Species Viewer provides nation-wide range maps and distribution models for amphibians, birds, mammals, and reptiles occurring in the continental U.S., Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. These kinds of maps and data are fundamental to assessing patterns of species richness and planning for the management of the nation's biological diversity.

Species of Greatest Conservation Need are lists of species designated in the 56 State Wildlife Action Plans which identify the species most in need of conservation action in that state or U.S. territory. USGS developed a process that allows these lists to be compiled into a national list, making their representation across taxa groups available via the Species Conservation Analysis Tool.

The Hazards Data Distribution System (HDDSExplorer) is an event-based interface that provides a single point-of-entry for access to remotely sensed imagery and other geospatial datasets as they become available during a response.

The GeoPlatform provides shared and trusted geospatial data, services, and applications for use by the public and by government agencies and partners to meet their mission needs.

Natural resources and environmental data, including orthoimagery, hydrologic, and cartographic data.

Find out how much rain has fallen—how many gallons have come down from the skies onto your roof, yard, block, or town.

The U.S. Geological Survey applied the SPARROW model to assess the loads delivered in 2002 for estuaries and coastal waters along the Atlantic Ocean and eastern Gulf of Mexico.

The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods. Alkalinity is for filtered samples, while ANC is for unfiltered samples. The results will be displayed in tabular and graphical form.

A map app to get recharge values from streamgage locations in Pennsylvania. Development of this app is described at the Related Science page.

An easy-to-use, Web-based geodatabase of historical flood and paleoflood information which includes links to sources of flood data.  The interface makes this collection of information useful to water-resource managers to better understand the historic events for improved flood-frequency estimates of the largest floods in Colorado. 

Web based application to compare, on a real-time basis, estimated dissolved-solids concentration and load as a surrogate for water-quality conditions in the Arkansas River and Fountain Creek in Colorado and determine whether future water-quality conditions are significantly different from background conditions.
