Interior West Forest Inventory & Analysis

Spatial representation of many forest attributes across the Interior West Region have been produced using a hierarchical modeling procedure. These forest attributes include: forest/nonforest mask, basal area, basal area by ponderosa pine species, biomass, crown cover, forest type/group, growth, quadratic mean diameter, stand age, stand density index, trees per acre, volume, and weighted stand height. The modeling procedure was based on a nonparametric approach that attempts to extract patterns between FIA plot data and several layers of geospatial predictor variables - principally from MODIS imagery.
