CMS: LiDAR-Derived Forest Biomass Maps at Four US Sites

High-resolution maps estimate aboveground biomass for four distinct US forest sites in 2011. The 11 GeoTIFF files provide carbon stock estimates at 20-50 meter resolution, generated by combining field inventory data with LiDAR remote sensing and modeling. Uncertainty estimates are included for the Maryland site using two different methodologies.

Use Cases

• Validating regional carbon stock models based on high-resolution, site-specific biomass maps.
• Assessing forest management impacts on carbon sequestration using data from four distinct biomes.
• Comparing biomass estimation uncertainty from different modeling methodologies provided for the Maryland site.
• Calibrating satellite-derived biomass products with ground-truthed LiDAR and field inventory data.

Strengths

• Provides uncertainty estimates for one site using two different modeling methodologies.
• Combines multiple data sources: field forest inventory and LiDAR remote sensing.
• Covers four distinct forested sites across the United States.

Limitations

• Metadata conflicts: last updated date differs significantly between sources (2011 vs. 2026).
• Limited spatial coverage to four specific sites, not a national or continuous map.
• Column names and detailed metadata for the GeoTIFF files are not provided.
