September 1, 2017 – Countdown to Landsat Pre-Collection Datasets Removal

During the week of October 1, 2017, Landsat 4-5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Operational Land Imager (OLI)/ Thermal Infrared Sensor (TIRS) Pre-Collection datasets will be removed from EarthExplorer.

Users have been encouraged to proactively use only Landsat Collection 1 datasets in their applications in preparation for this.

All Landsat Collection 1 data for Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI/TIRS have completed processing and are available for download from EarthExplorer.

Landsat 1-5 Multispectral Scanner (MSS) data will be processed into the Collection 1 Level-1 inventory after data quality analysis and processing level investigations have been completed, which is anticipated to occur by December 2017. The Landsat 1-5 MSS “Pre-Collection” dataset will remain available on EarthExplorer until the dataset is processed into the Collection 1 archive structure.

Please visit the Landsat Collections webpage for information on the Landsat Collection 1 effort or contact User Services with questions.
