Tools and Data


Examples of Requests


FIA data can be used as a source of ‘ground truth’ to investigate the accuracy of a land classification map by intersecting plot locations with the map. An error matrix or ‘confusion matrix’ can be created which summarizes how frequently the classification agrees with the observed plot data.

 

FIA data can be used to identify areas of good or poor wildlife habitat. This is usually done by summarizing FIA tree data by size class and species to see if the structure required by a certain wildlife species exists in a given region.

 

Observations of standing dead trees and downed woody debris can be used as inputs to a model of forest fire fuels.


Intersection of plots with a soils polygon layer to provide summaries by a soils attribute.
