August 22, 2018 - Landsat 9 Element Critical Design Reviews Successfully Completed

Landsat 9 Ground System Element Critical Design Reviews (CDR) were successfully completed in June, July and August for three elements of the ground system (read more).

December 23, 2014 - Provisional Landsat 8 Surface Reflectance Data Available

Provisional Landsat 8 Operational Land Imager (OLI) Surface Reflectance (SR) data products are now available through the Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On Demand Interface and EarthExplorer. (Read More)

December 3, 2014 - Landsat 8 Surface Reflectance Climate Data Record Development Nears Completion

By the end of 2014, Prototype Landsat 8 Operational Land Imager (OLI) Surface Reflectance (SR) Climate Data Records (CDRs) will be available through the Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On Demand Interface.  As currently produced for Landsat 4-5 and Landsat 7 scenes, product options such as top-of-atmosphere (TOA) reflectance, surface reflectance (SR), and SR-based spectral indices will be available for Landsat 8 scenes.

Details about Landsat 8 Surface Reflectance CDRs are now available.

April 21, 2014 - UPDATE on Landsat Surface Reflectance Climate Data Record Sample Data

Several changes will be implemented for Landsat Surface Reflectance CDRs on July 30, 2014. These include:

  • Output file format options in HDF, GeoTIFF, or Binary
  • Metadata delivery in XML
  • Band 6 Brightness Temperature in Kelvin

March 28, 2014 - Upcoming Changes to Landsat Surface Reflectance Climate Data Records, Sample Data Available

In the near future, several changes will be made to the processing and output options of SR CDR products. One change will allow users to select from three output formats: HDF, GeoTIFF, or Binary. (Surface Reflectance data products requested from EarthExplorer will be delivered in GeoTIFF format only.) The metadata will be delivered in an Extensible Markup Language (.XML) file. The brightness temperature delivered as Band 6 in the top of atmosphere (TOA) reflectance product will be labeled in Kelvin instead of currently-noted Celsius.

January 3, 2013 - Surface Reflectance Data Available

Landsat Surface Reflectance Climate Data Records (CDR) for Global Land Survey (GLS) collections 2000, 2005, and 2010 are now available from the Landsat CDR/ECV data set on EarthExplorer.

The Surface Reflectance CDR is one of a number of Higher-Level Landsat data products produced to support land surface change studies.

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.
