The U.S. Department of Agriculture, Forest Service, Forest Inventory
and Analysis (FIA) Program provides all sorts of estimates of forest
attributes for uses in research, legislation, and land management. The
FIA uses a set of criteria to classify a plot of land as “forested” or
“non-forested,” and that classification is a central data point in many
decision-making contexts. A small subset of plots in Washington State
are sampled and assessed “on-the-ground” as forested or non-forested,
but the FIA has access to remotely sensed data for all land in the
state. forested is an R data package containing a data
frame, forested, from which we can develop a model on the
more easily-accessible remotely sensed data to predict whether a plot is
forested or non-forested.
