Harmonized Landsat Sentinel-2 (HLS)

Learn More About HLS

This 2024 Normalized Difference Vegetation Index (NDVI) image from the HLS project shows the degree of land use change in a region of Western Brazil. Green areas with high NDVI values indicate healthy vegetation while tan and brown areas with low NDVI values indicate soil or barren areas.

The Harmonized Landsat Sentinel-2 Project Releases Vegetation Indices

These new vegetation indices offer the same near-global coverage, and 30-meter spatial resolution as the initial HLS products.

Harmonized Landsat Sentinel-2 (HLS) Code Now Openly Available

The release of the HLS codebase gives product users greater visibility into the project’s image processing pipeline.

HLS: Two Together Better than Two Apart

The purpose of the Harmonized Landsat Sentinel-2 (HLS) project led by IMPACT, is to combine two or more data streams into a single data set and increase their value.

IBM Geospatial Foundation Model Trained with HLS Data

In partnership with IBM, NASA constructed the first geospatial foundation model specifically trained with Earth observation satellite imagery.
