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), and LCMAP CCDC Collection 2.x data sets will be tied to Landsat Collection 2 ARD.  

Minor dot releases (e.g., LCMAP CCDC 1.2) generally represent algorithm refinements or additional annual products years due to more recent base input data. For example, two additional years of Landsat Collection 1 ARD data were used in LCMAP Collection 1.1, shifting the provisional year from 2017 (in 1.0) to 2019 (in 1.1).
