Samples and 4-class predictions of agroforest-forest frontiers mapping in Peru

This is a database for the study of agroforest-forest frontiers mapping conducted by Wanting Yang, etc. The data contained in the repository includes two parts. 1. the training samples(polygons and rectagle_roi) annotated with Google Earth as reference. We used Google Earth Pro to make the date of Google Earth imagery match with PlanetScope imagery. 2. the prediction from the 4-class model. Users can visualize the data with QGIS or other GIS software.
