The USFS FIA program
The U.S. Forest Service Forest Inventory and Analysis (FIA) program collects detailed forest measurements over a national network of field plots. Over 3500 plots are distributed throughout the state of Maine. New measurements are collected at each plot every 5 years. Each year 20% of plots are revisited. We use FIA data to train and validate machine learning models used to map forest conditions. The FIA program maintains the confidentiality of true plot locations to protect the privacy of landowners and to preserve plot integrity. True locations are made available for use through collaborative agreements with the USFS Northern Research Station FIA Program. Our use of true plot locations is subject to data security and nondisclosure agreements.
