Data Analysis Tools

How does your state use Landsat satellite data? Find out here! For each state, you can download a satellite image, put together an online puzzle, or read a USGS Fact Sheet that contains information about the benefits of Landsat.

The Invasive Carp Open Data Hub is a platform for exploring and accessing USGS data, tools, applications, and publications related to invasive carp research and management.

Streams, rivers, lakes and reservoirs are important natural resources for irrigation, public supply, wetlands and wildlife. Excess precipitation that flows into these sources is called runoff, and it's an important drought indicator. The California Water Science Center tracks both monthly and annual runoff.

The PeakFQ application performs peak-flow frequency analysis to evaluate flood frequency on rivers and streams.

This data visualization displays the results of distribution models for 130 snake and lizard species in western North America under six time-by-climate scenarios.

The USGS EROS Cal/Val Center of Excellence (ECCOE) Landsat Cal/Val Team, along with their NASA counterparts, maintains primary responsibility for radiometric and geometric characterization and the calibration and validation of the Landsat instruments and spacecrafts. This work includes both the ongoing operations of active Landsat missions, as well as the retired Landsat missions.

The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in support of watershed restoration initiatives occurring in Philadelphia.

The USGS Groundwater Climate Response Network (CRN) is a system of wells and springs selected to monitor the effects of climate variability on groundwater systems nationwide.

The Earth Observing Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry. This information compiled by staff at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.

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.

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

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.
