Test of HLS algorithm
!!! It is not official version of HLS !!!
Algorithm is in two parts. In first, atmospheric correction have to be processed (folder Atmospheric_correction). Then, the other parts (coregistration, resampling, BRDF-normalization, bandpass adjustment) are in scripts in folder HLS.
Input images are :
- Sentinel-2 : L1C
- Landsat 8 : Collection 1 Level 1
- Landsat 7 : Collection 1 Level 1
- Landsat 5 : Collection 1 Level 1
Input images for Landsat should be collection 2 but LaSRC for collection 2 is not available. It is the main problem of this algorithm. For Landsat 7 and Landsat 5, it is only an attempt. Values for bandpass adjustment come from : D.P.Royet al. “Characterization of Landsat-7 to Landsat-8 reflective wavelength and norma-lized difference vegetation index continuity”
Results are in EPSG:32633.
In Test folder, there are scripts which enable to calculate differences between results.
