NASA - First-of-its-Kind Map Depicts Global Forest HeightsUsing NASA satellite data, scientists have produced a first-of-its kind map that details the height of the world’s forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method.
