Patch-Based Forest Change Detection from Landsat Time Series

Acceso

M. Joseph Hughes, S. Douglas Kaylor and Daniel J. Hayes

In the species-rich and structurally complex forests of the Eastern United States, disturbance events are often partial and therefore difficult to detect using remote sensing methods. Here we present a set of new algorithms, collectively called Vegetatio... ver más
