Estimating Leaf Area Index From Satellite Imagery Using Bayesian Networks

Kalacska, Margaret; Sanchez-Azofeifa, G Arturo; Caelli, Terry; Rivard, Benoit; Boerlage, Brent


In this study, we investigated the use of Bayesian networks for inferring tropical dry forest leaf area index (LAI) from satellite imagery in dry and wet seasons. LAI was chosen as the variable of interest because leaf area is the exchange surface between the photosynthetically active component of the canopy and the atmosphere. Initial network estimates were obtained from ground truth plot data with known forest structure, LAI, and satellite reflectance in the red and near-infrared bands (as...[Show more]
