Continuous monitoring of forest change dynamics with satellite time series por Decuyper, M., Chávez, R.O., Lohbeck, M., Lastra, J.A., Tsendbazar, N.E., Hackländer, J., Herold, M., Vågen, Tor-Gunnar

“…We showed that the algorithm is capable of capturing small-scale (gradual) changes (e.g. selective logging, forest edge logging) and the multiple changes associated to shifting cultivation. The performance of the algorithm has been shown at regional scale, but if larger scale studies are required a representative selection of reference forest types need to be selected carefully. …”
