Product Content
The HLS 30m Landsat product consists of surface reflectance and brightness temperature derived from all Landsat L1TP input. The product is gridded with the Sentinel-2 tiling system and includes view angle normalization (nadir view) for the solar reflective bands.
Product specification
- Spatial: 30 m
- Spectral: As input
- Temporal: All Landsat-8/9 L1TP products in Collection-2
- Nadir view adjustment: Yes
Spatial resampling algorithm
Cubic convolution is used to resample Landsat OLI/TIRS 30m spectral data into MGRS, to account for the pixel positioning difference between Landsat and Sentinel-2 tiling (USGS places the UTM coordinate origin at a pixel center, while ESA places the origin at a pixel corner) and that Landsat and Sentinel-2 input can come from two different UTM zones.
File Naming
Each data layer is saved in a separate Cloud Optimized GeoTIFF (COG) file. File naming follows a format:
HLS.L30.T<Tile_ID>.<year><doy>T<HHMMSS>.v<version number>.<Band>.tif
