The fill values and scale factors of Landsat Collection 2 Level-2 products were updated to be consistent with that of Landsat Collection 2 Level-1 data, while using the unsigned integer data type more efficiently.
As shown in the table below, the fill value of the Surface Reflectance and Surface Temperature bands were changed from “-9999” in Collection 1, to “0” in Collection 2 to be consistent with the Level-1 data (digital numbers).
The updated multiplicative scale factors, along with the additive scale factors, provide a full range of physical values based on the valid range allowed by data type.
|Surface Reflectance||Surface Reflectance||Surface Temperature||Surface Temperature|
|Collection 1||Collection 2||Collection 1||Collection 2|
|Scaling Factor||0.0001||0.0000275 + -0.2||0.1||0.00341802 +149.0|
|Data Type||Signed 16-bit integer||Unsigned 16-bit integer||Signed 16-bit integer||Unsigned 16-bit integer|
