LCMAP Collections ensure that all LCMAP science products are consistently processed and retain traceability of data quality provenance. Check out the links below to learn more about the differences between available LCMAP CONUS science product collections.

Visit the Collection 1.0 LCMAP Product Information Page to learn more about the initial LCMAP product release.

A new LCMAP Collection occurs when there are changes or refinements to the algorithms, or when the input data is updated.  

A major Collection release is generally tied to a fundamental change in the base input data for change detection. For example, LCMAP CCDC 1.x data sets are tied to Landsat Collection 1 Analysis Ready Data (ARD).  

Minor dot releases (e.g., LCMAP CCDC 1.3) generally represent algorithm refinements or additional annual products years due to more recent base input data. For example, one additional year of Landsat Collection 1 ARD data were used in LCMAP Collection 1.3, shifting the provisional year from 2020 (in 1.2) to 2021 (in 1.3).
