Using FIESTA , an R-based tool for analysts, to look at temporal trends in forest estimates

Publications Posted on: February 01, 2013
FIESTA (Forest Inventory Estimation for Analysis) is a user-friendly R package that supports the production of estimates for forest resources based on procedures from Bechtold and Patterson (2005). The package produces output consistent with current tools available for the Forest Inventory and Analysis National Program, such as FIDO (Forest Inventory Data Online) and EVALIDator.

Attributing causal agents to nationwide maps of forest disturbance
