*data products*

## Specifications

- **spectral band count**: 13
- **gsd m**: {"native":30}
- **file format**: Cloud Optimized GeoTIFF
- **access endpoint**: https://doi.org/10.5067/HLS/HLSL30.002

- **licence**: NASA Earthdata Use Policy
- **primary data portal url**: https://search.earthdata.nasa.gov/search?q=HLS
- **use cases**: ["Input stack for vegetation disturbance detection (OPERA DIST-ALERT-HLS)","Multi-year NDVI and vegetation index time series at 30 m","Deforestation and forest degradation monitoring using Landsat plus Sentinel-2 fusion","EUDR supply-chain due diligence requiring high temporal-density optical coverage","Land cover change analysis across Landsat and Sentinel-2 archives","Agricultural monitoring and crop type mapping"]
- **practical limitations**: ["Two distinct sub-products (HLSL30 v2.0 from Landsat, HLSS30 v2.0 from Sentinel-2) share the same processing chain but have different band sets; spectral_band_count above (13) reflects S30; L30 has 11 bands including two TIRS thermal channels","L30 thermal bands (TIRS B10/B11) are resampled from native 100 m to 30 m and are brightness temperature, not surface reflectance","S30 Red-Edge bands (B05/B06/B07) retain original MSI spectral response and are not adjusted to OLI; cross-sensor red-edge time series require caution","BRDF correction accuracy primarily enhanced in areas below 65 degrees north latitude","2 to 3 day data latency from acquisition to product availability (not near-real-time)","Optical only; cloud cover reduces effective temporal density in humid tropics"]
- **known artefacts**: ["Aerosol QA bits added in V2.0; V1.x archives lack these aerosol quality flags","Fmask cloud masking inherited from source products; known commission and omission errors in complex scenes"]
- **last verified date**: "2026-05-18T00:00:00.000Z"
- **verified by**: agency-doc
- **claim status**: agency-verified
- **deployment context**: orbital
