HLS Vegetation Indices: Daily Global Landsat 8/9 Data at 30m Resolution

Daily global observations from 2013 onward, derived from Landsat 8 and Landsat 9 satellites. The dataset provides nine vegetation health indicators, including NDVI and EVI, at a 30-meter spatial resolution, gridded to the Military Grid Reference System for time-series analysis. It is produced by NASA and the USGS as part of the Harmonized Landsat and Sentinel-2 project.

Use Cases

• Tracking changes in vegetation over time based on the nine provided vegetation indices.
• Identifying areas of vegetation stress or deforestation based on index anomalies.
• Assessing crop health and agricultural productivity based on vegetation index values.
• Monitoring post-fire recovery and burn severity based on the Normalized Burn Ratio indices.

Strengths

• Provides nine specific vegetation indices, including NDVI, EVI, and NBR.
• Data is harmonized and 'stackable' with Sentinel-2 products for consistent time-series analysis.
• Offers a high spatial resolution of 30 meters and a high temporal cadence of 2–3 days globally.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and exact file sizes are unknown, which may limit suitability assessment.
