Landsat Collections: Providing a Stable Environmental Record for Time Series Analysis
Why are the fill values and scaling factors of Landsat Collection 2 Level-2 products different from those products in Collection 1?
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 | |
Fill Value | -9999 | 0 | -9999 | 0 |
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 |
