Photo of A subset of the landscape in Montana’s Swan Valley (top panel). The lower panel shows the plot IDs for the best-matching plot for each pixel of the same landscape, with each color representing a unique plot. In the left half of the imagery, the landscape is dominated by a checkerboard pattern, the legacy of extensive timber harvest on private lands, and less extensive harvest on public lands. On the right side of the imagery, vegetation is dominated by topographic gradients in a mountainous landscape. The model was able to pick up these patterns, with the outline of the checkerboard visible in the left half of the lower panel, and the topographic gradients visible in the clustering of the plots on the right half of the panel.
