This geospatial dataset represents the first attempt by the FIA Remote Sensing Band (RSB) to address the need for a geospatial data showing the extent and distribution of forest biomass in greater detail than is possible with the FIA plot data alone. This map was created by modeling forest biomass collected on FIA sample plots as functions of more than sixty geospatially continuous predictor layers. Nearly one-half million FIA sample plots nationwide were used to develop these models. RSB scientists from each FIA unit were responsible for the development of the FIA plot data for their unit. The geospatial predictors were produced at the USFS Remote Sensing Applications Center (RSAC) with a moderate resolution (250 meters) that is appropriate for the scales of analyses that FIA plot-based estimates support. Among the predictor layers used were digital elevation models (DEM) and DEM derivatives; Moderate Resolution Spectroradiometer (MODIS) multi-date composites, vegetation indices and vegetation continuous fields; class summaries from the 1992 National Land Cover Dataset (NLCD); various ecologic zones; and summarized PRISM climate data.
