Description
This product is part of the TreeMap data suite. It provides detailed spatial information on forest characteristics including number of live and dead trees, biomass, and carbon across the entire forested extent of the continental United States in 2016.
TreeMap v2016 contains one image, a 22-band 30 x 30m resolution gridded map of the forests of the continental United States circa 2016, with each band representing an attribute derived from select FIA data (and one band representing the TreeMap ID). Examples of attributes include forest type, canopy cover percent, live tree stocking, live/dead tree biomass, and carbon in live/dead trees.
TreeMap products are the output of a random forest machine learning algorithm that assigns the most similar Forest Inventory Analysis (FIA) plot to each pixel of gridded LANDFIRE input data. The objective is to combine the complimentary strengths of detailed-but-spatially-sparse FIA data with less-detailed-but-spatially-comprehensive LANDFIRE data to produce better estimations of forest characteristics at a variety of scales. TreeMap is being used in both the private and public sectors for projects including fuel treatment planning, snag hazard mapping, and estimation of terrestrial carbon resources.
TreeMap is distinct from other imputed forest vegetation products in that it provides an FIA plot identifier to each pixel whereas other datasets provide forest characteristics such as live basal area (e.g., Ohmann and Gregory 2002; Pierce Jr et al. 2009; Wilson, Lister, and Riemann 2012). The FIA plot identifier can be linked to the hundreds of variables and attributes recorded for each tree and plot in the FIA DataMart, FIA's public repository of plot information (Forest Inventory Analysis 2022a).
The 2016 methodology includes disturbance as a response variable, resulting in increased accuracy in mapping disturbed areas. Within-class accuracy was over 90% for forest cover, height, vegetation group, and disturbance code when compared to LANDFIRE maps. At least one pixel within the radius of validation plots matched the class of predicted values in 57.5% of cases for forest cover, 80.0% for height, 80.0% for tree species with highest basal area, and 87.4% for disturbance.
