Figures
Fig. 1 Selected examples of Hansen et al.’s (1) failures in classifying of tree plantations (A to E) and herbal crops (F to H) as forest. All the maps are screenshots from Hansen et al.’s supplementary online map application (http://earthenginepartners.appspot.com/science-2013-global-forest) taken in November 2013 and modified to highlight details by adding the yellow squares. The colors in the right halves of each panel indicate stable forest (green), forest loss (red), forest gain (blue), and forest loss and gain (magenta). See Table 1 for more details, including coordinates, and for several additional examples.

Geographic coordinates allow easy checking of current vegetation in the supplementary online map application (http://earthenginepartners.appspot.com/science-2013-global-forest). Hundreds of additional examples of similar errors can easily be found in the application map by simply following plantation maintenance roads. Often, even details such as individual oil palms or soybean rows are clearly visible.
