These maps show forest canopy heights throughout the Earth and the United States. The data was obtained from NASA’s ICESat, Terra, and Aqua satellites and processed by Michael Lefsky. The shades of green show the height of the forest canopy from 0 to 230 feet. For any patch of forest, the height shown means that 90 percent or more of the trees in the patch are that tall or taller.
More information about the maps and the data can be found at the websites below:
There are two maps available. The first shows the forest height over the entire globe. The second is a more detailed map of the forest height for the United States. There is also a Google Earth version of the global map that can be downloaded using the button below.
