Seeing the forest for the trees
High-Resolution Global Maps of 21st-Century Forest Cover Change. Hansen et al.
annotated by Hilary Barker
Our understanding of how forests change remains limited, due to our inability to observe them over time. In this study, Hansen et al. use satellite imagery (Landsat) to map global-scale forest cover changes...
