The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey.
On July 23, 1972, in cooperation with NASA, the Earth Resources Technology Satellite (ERTS-1) was launched. It was later renamed Landsat 1. Additional Landsat satellites followed in the 1970s and 1980s. Landsat 7 was launched in 1999 followed by Landsat 8, launched on February 11, 2013.
Both Landsat 7 and Landsat 8 are currently in orbit and collecting data. Landsat 9 is in development, and has a launch readiness date of mid-2021.
Landsat satellites have the optimal ground resolution and spectral bands to efficiently track land use and to document land change due to climate change, urbanization, drought, wildfire, biomass changes (carbon assessments), and a host of other natural and human-caused changes.
The Landsat Program’s continuous archive (1972-present) provides essential land change data and trending information not otherwise available. Landsat represents the world's longest continuously-acquired collection of space-based moderate-resolution land remote sensing data. Landsat is an essential capability that enables the U.S. Department of the Interior to wisely manage Federal lands. People around the world are using Landsat data for research, business, education, and other activities.
Many image processing programs (ERDAS IMAGINE®, PCI Geomatica®, ENVI®, IDRISI®, etc.)* can import a variety of image formats, including the GeoTIFF files of Landsat data.Free Multispec software that is included with the USGS lesson plan Tracking Change Over Time can be used for limited spectral analysis.To view Landsat scenes without using specialized software, download the LandsatLook images (...
The Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands--or channels--of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), one can determine which bands of the selected sensor will...
Landsat scenes directly downlinked to the USGS EROS Landsat Ground Station become available through EarthExplorer within 6 hours after acquisition, and then become visible in GloVis and the LandsatLook Viewer within 24 hours.Scenes downlinked to other USGS Ground Stations can be available within 1 to 2 weeks. Scenes downlinked to International Ground Stations may become available in the USGS...
There are no restrictions on Landsat data downloaded from the USGS; it can be used or redistributed as desired. We do request that you include a statement of the data source when citing, copying, or reprinting USGS Landsat data or images.Details are on the EROS Data Citation page.Learn more: USGS Copyrights and Credits statement
Data acquisition requests are not available to the public. The Landsat 8 and Landsat 7 satellites each acquire data on a continual basis in accordance with their respective Long Term Acquisitions Plans.The Landsat Acquisitions page has calendars and information about daily schedules.Learn more:Landsat 8 Long Term Acquisitions PlanLandsat 7 Long Term Acquisitions Plan
Landsat data products held in the USGS archives can be searched and downloaded at no charge from a variety of sources. Visit the Landsat Data Access web page for information about how Landsat data products can be downloaded individually or in bulk.Landsat imagery not found in the USGS archive might have been collected by one of the USGS International Cooperator ground stations, each of which are...
There are several Landsat data products that are useful for science applications and land use/land change studies:Landsat Collections Level 1 - Ensures that the data in the Landsat Level-1 archive are consistent in processing and data quality to support time-series analyses and data stacking. Each Level-1 data product includes individual spectral band files, a metadata file, and additional...
When it comes to mining remotely sensed data, Landsat Level-3 science products offer what some might call land cover gold.
In the old days, before 2008, a view of planet Earth from space often came at a cost.
Access to consistent high-quality images to study changes on Earth’s surface is getting easier. The USGS Landsat standard (Level-1) product inventory...
