Data Analysis Tools

Species observations for the United States and Territories.

The Test Site Catalog contains information about worldwide radiometric, geometric, and spatial calibration sites used for post launch characterization and calibration of Earth observation sensors.

This application provides a set of interactive data visualization tools to explore datasets generated by USGS researchers for the RESTORE project. The purpose of this tool is to help stakeholders, decision makers and other interested users access these datasets and develop a better understanding of spatial and temporal streamflow patterns in the Lower Mississippi-Gulf Region.

The USGS National Climate Change Viewer (NCCV) is a web application for visualizing climate change projections across the conterminous United States. Users can visualize projected changes in climate and water balance by state, county or USGS Hydrologic Units.

The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

WaterQualityWatch provides access to real-time water-quality data collected at more than 2,000 stream sites throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.

This mapper identifies USGS Federal Priority Streamgages (FPS). FPS are monitoring stations that track the amount of water in streams and rivers across the Nation to meet long-term federal information needs. They are strategically positioned to serve as a backbone for the larger National Streamflow Network that is operated in cooperation with over 1,200 federal, state, tribal, and local agencies.

A majority of the water in the western U.S. comes from snowmelt, but changes in the timing, magnitude, and duration of snowmelt can alter water availability downstream. This data visualization story explores what changing snowmelt means for water in the West, and how new USGS efforts can advance snow science by modeling snowpack and snowmelt dynamics and linking these results to streamflow.

Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin.

The Map and Data Products page offers bulk download of the Fire Danger Forecast data suite.

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.
