G-LiHT Hyperspectral Vegetative Indices: 44 Science Layers at 1-Meter Resolution

The G-LiHT airborne imaging system maps terrestrial ecosystems across North America. This data product provides 44 science dataset layers of vegetative and stress indices, such as NDVI and Carter Stress, processed as GeoTIFF rasters at 1-meter spatial resolution. The data is produced by NASA's Goddard Space Flight Center and was last updated in March 2026.

Use Cases

• Assessing forest health and composition based on vegetative indices like NDVI, TVI, and RDVI.
• Monitoring plant stress and environmental impacts using stress indices such as Carter Stress and Vogelmann Stress.
• Conducting high-resolution spatial analysis of terrestrial ecosystems using 1-meter resolution raster data.

Strengths

• Provides 44 distinct science dataset layers for detailed analysis.
• Offers high spatial resolution at 1 meter for precise mapping.
• Covers a broad diversity of forest communities and ecoregions in North America.

Limitations

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