Landsat Missions

USGS Landsat Global Archive

You are here

Landsat satellites have acquired data from across the globe for more than four decades. The National Satellite Land Remote Sensing Data Archive (NSLRSDA) at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center holds the single most geographically and temporally rich collection of Landsat data in the world, currently holding more than three million Landsat scenes.

A file (in bold below) has been created to geographically show the number of scenes that are archived at the EROS Center, by acquisition year. Each page shows the year of acquisition, and from which satellite and sensor the data were acquired. Because most years have multiple maps associated with several satellites and sensors, the slides have been sorted by date, then satellite, then sensor.

These maps show only what is held at the USGS EROS Center at time of file creation. There may be data that are not yet archived, as some data were downlinked to International Ground Stations over the years. (The Landsat Global Archive Consolidation (LGAC) effort started in 2010, with a goal to consolidate the Landsat archives of all stations worldwide into the USGS EROS Archives.) As scenes are received in support of LGAC, the maps will be updated appropriately.

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.

Landsat Updates

The Landsat Update is an informal communication tool, prepared periodically and distributed electronically to USGS Landsat partners, to provide information about Landsat activities and related topics of interest.
