    dct:description """<b><font size='5'>Executive Statement </font></b><div>To support analysis of the Landsat long-term data record that began in 1972, the USGS
Landsat data archive was reorganized into a formal tiered data collection structure.
This structure ensures all Landsat Level 1 products provide a consistent archive of
known data quality to support time-series analysis and data “stacking”, while controlling
continuous improvement of the archive, and access to all data as they are acquired.
Collection 1 Level 1 processing began in August 2016 and continued until all archived
data was processed, completing May 2018. Newly-acquired Landsat 8 and Landsat 7
data continue to be processed into Collection 1 shortly after data is downlinked to
USGS EROS.</div><div>Learn more: </div><div>https://www.usgs.gov/media/files/landsat-collection-1-level-1-product-definition <b><br /></b></div>""" ;
