U.S. Forest Stand Density Rasters at 30m Resolution from TreeMap 2020

Three 30-meter resolution raster layers for the continental United States provide wall-to-wall metrics of forest size-density. The dataset includes Stand Density Index (SDI), Maximum Stand Density Index (SDImax), and Relative Density (RD), derived from the TreeMap 2020 dataset and Forest Inventory and Analysis (FIA) plot data. Author Emmerson Chivhenge published this dataset on figshare in April 2026.

Use Cases

• Modeling forest growth and mortality based on stand density metrics.
• Assessing forest health and resilience using the relative density ratio.
• Mapping potential wildfire risk across the continental U.S. based on tree density.
• Calibrating or validating other forest attribute models using the SDI and SDImax rasters.

Strengths

• Wall-to-wall coverage for the continental United States provides a complete spatial picture.
• 30-meter resolution offers detailed, landscape-scale analysis capabilities.
• Derived from established public data sources: TreeMap 2020 and FIA plot data.
• Includes three complementary metrics (SDI, SDImax, RD) for multifaceted analysis.

Limitations

• The dataset size is listed as 0.0 B, indicating the actual data files may not be present or the metadata is incomplete.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or methodological bias inherent to the source TreeMap 2020 model.
