This is a crucial helper script, modified from a common GEE LandTrendr utility.
It is responsible for fetching, preprocessing, and harmonizing Landsat 4, 5, 7, 8, and 9 Surface Reflectance (SR) collections.
Functions include scaling SR values, renaming bands for consistency, and applying cloud, shadow, and snow masks.
The getCombinedSRcollection function is extensively used by the other applications to acquire analysis-ready SR data. |
