The EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat satellites orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from previous Landsat overpasses. When Landsat satellites are out of viewing range of a ground station, the most recent overpass is displayed.

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.

IntELiMon (Interagency Ecosystem LiDAR Monitoring) Interactive Viewer

Providing the longest continuous science record of the Earth’s surface from space.

The USGS Earth Resources Observation and Science (EROS) Registration System (ERS) consolidates user profile information and authentication for EROS based web services.

The Landsat Reprocessing Application allows you to discover scene and tile products that have been changed by reprocessing.

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 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.

For 50 years, the EROS Center has been archiving and distributing satellite, aerial, and mapping data amidst farmland north of Sioux Falls, South Dakota. We invite you to explore the surprising history and cutting-edge science and research performed at EROS every day.

The Spectral Characteristics Viewer allows users to determine which satellite bands are best suited for research applications.

We’ve created fun and engaging educational lessons that allow students to look at satellite imagery and perform the same analysis as our remote sensing scientists at EROS. Students of all ages can learn how remote sensing scientists use Landsat satellite data to track changes to the Earth’s surface over the years. We’ve also added a few games and puzzles so you can test your skills too.

At EROS we take pride in our images! Here you can find a vast collection of our favorites, whether you are looking for your home state, imagery for an event, or something purely artistic. Select a category to get started.
