May 28, 2015 - Landsat 8 Surface Reflectance Processing Resumes

Surface Reflectance processing has resumed for Landsat 8 scenes acquired after December 18, 2014. The higher level processing was suspended during the thermal sensor (TIRS) side-b electronics swap. See the Landsat Higher Level Science Data Products Web page for more details.

May 27, 2015 - Upcoming Changes to LandsatLook Geographic Bundle Product Format

On June 3, 2015, the format of the files contained in the LandsatLook Geographic Bundle product will be changing from the current .jpg images, to geoereferenced GeoTIFF files.

May 18, 2015 - Landsat 8 TIRS Reprocessing Complete

The reprocessing effort to provide valid thermal data for Landsat 8 scenes acquired December 19, 2014 to March 13, 2015 has been completed. The reprocessing was done in response to the TIRS side-b electronics swap that is documented on the May 8, 2015 Calibration Notice. 

May 7, 2015 - Upcoming Website Unavailability

On Thursday, May 21, 2015, this site will become unavailable at 6:00 pm CT, until 9:00 pm CT due to USGS EROS network upgrades. We apologize for any inconvenience this may cause.

May 1, 2015 - 2015 William T. Pecora Award Announcement

Nominations for the William T. Pecora Award, presented annually to individuals or groups that have made outstanding contributions toward understanding the Earth by means of remote sensing, must be received by June 15, 2015. See the latest Landsat Update for more details.

April 27, 2015 - Continuing the Land Imaging Mission; NASA, USGS Begin Work on Landsat 9

NASA and the U.S. Geological Survey (USGS) have started work on Landsat 9, planned to launch in 2023, which will provide mission-critical continuity in the Earth-observing program’s record of land images. (Read More)

April 23, 2015 - Landsat 8 Data Processing Changes

New production code was released today to enhance the usability of Landsat 8 products. Some of the planned changes were postponed in favor of coordinating new features in Landsat 8 with similar changes in Landsats 4-7 TM and ETM+ scheduled for the fall/winter of 2015. Other features expected to impact users have also been added since the last Landsat Update published February 27. Please see this month's Landsat Update for details.

April 16, 2015 - Landsat 8 Thermal Data Reprocessing Update

On March 6, 2015 we reported that the Landsat 8 Thermal Infrared Sensor (TIRS) resumed normal imaging operations, and outlined plans for reprocessing data acquired since December 19, 2014, when problems occurred in the A-side electronics of the sensor. Provisional TIRS data acquired since March 13, 2015 were expected to require reprocessing to refine the absolute calibration; however, based on a small number of vicarious measurements, it has been determined that these data will not need to be reprocessed for now since the radiometry appears to be consistent with the previous A-side data. The calibration will be monitored and updated in the future if needed. (Read More)

March 26, 2015 - Data Downloads Unavailable

All Landsat 1-8 data product downloads will be unavailable from 12:00 am to 8:00 am CT on Friday, March 27, 2015 due to archive maintenance. We apologize for any inconvenience this may cause.

March 20, 2015 - Attention Landsat Data Users

The Landsat 1-7 browse and full resolution browse products for MSS, TM and ETM+ data need to be reprocessed to correct a recent problem. The issue should be resolved by March 23, 2015. This Landsat browse problem does not affect the quality or usability of other Landsat data downloads.

Thank you for your patience in this matter.

March 16, 2015 - Landsat 8 Thermal Data Processing Resumed

On March 13, 2015 at 4:00 pm CT, processing of Landsat 8 Thermal Infrared Sensor (TIRS) data resumed. The newly processed data includes the revised Calibration Parameter Files established after the mechanism control electronics (MCE) swap on March 2, 2015. Investigations are continuing to improve the data product, and reprocessing of TIRS data acquired since December 19, 2014 is still planned according to the March 6, 2015 Headline.

March 13, 2015 - Landsat Data Processing Changes Scheduled

On Tuesday March 17, 2015, the changes described in the recent Landsat Update will be implemented, starting at 8 am CT and lasting for up to four hours. Newly acquired Landsat 7 data will be processed and made available when the systems resume nominal operations. We apologize for any inconvenience this may cause.

March 12, 2015 - Upcoming Landsat 8 Data Unavailability

​Landsat 8 data will become unavailable for download on Tuesday March 17, 2015, at 6:00 am CT for system upgrades. The upgrades are expected to take up to 6 hours. We apologize for any inconvenience this may cause.

March 6, 2015 - Landsat 8 TIRS Sensor Resumes Nominal Operations

The Landsat 8 Thermal Infrared Sensor (TIRS) resumed normal imaging operations on March 4, 2015, and nominal blackbody and deep space calibration data collection will resume on March 7, 2015. (Read More)

February 27, 2015 - Upcoming Landsat data changes

A number of changes affecting Landsat data are planned to take place during the Spring of 2015. The Landsat Update published today provides updated information about these planned changes.

February 26, 2015 - Landsat 8 Thermal Sensor Update

After extensive investigation and testing, the decision has been made to switch the TIRS Mechanism Control Electronics from the primary to redundant side on Monday, March 2, 2015. (Read More)

February 20, 2015 - Landsat 8 Thermal Sensor Update

The Landsat 8 satellite continues to acquire data from both onboard sensors, however Level-1 processing of Thermal Infrared Sensor (TIRS) data remains suspended – TIRS data bands currently consist of only zero-fill. (Read More)

February 19, 2015 - Landsat Goes Over the Top

On June 21, 2014, Landsat 8 acquired an unbroken swath of 52 individual scenes over the Arctic. The midnight sun of the summer solstice allowed scientists to see more of the color and diversity of snow, ice, and cloud formations. Starting in Scandinavia, Landsat 8 cut across the Arctic Circle, northern Greenland, and through Canada’s Nunavut and Northwest Territories. (Read More)

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.
