This image of forest in Traustein, Germany, shows how radar can accurately measure changes in forest height over time. Red corresponds to forest parcels where height has been reduced by 5–10 m between 2003 and 2009, possibly owing to logging or storm damage. By contrast, blue corresponds to forest that has grown by 5–10 m over the same time. Green depicts little change.
