National Forest Type Dataset

This geospatial dataset was created by the USFS Forest Inventory
and Analysis (FIA) program and the Remote Sensing Applications
Center (RSAC) to show the extent, distribution, and forest
type composition of the nation’s forests. The dataset was created
by modeling forest type from FIA plot data as a function
of more than one hundred geospatially continuous predictor
layers. This process results in a view of forest type distribution
in greater detail than is possible with the FIA plot data
alone. Nearly one-half million FIA sample plots nationwide
were used to develop these models. 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. Modeling was performed using
a data mining package, Cubist/See5TM, which was loosely coupled with
Leica Geosystems ImagineTM image processing software.
