Map reveals height of the world's forests

Satellite maps can show everything from city blocks to inaccessible mountain peaks from the comfort of our living rooms. Now, they can show us yet another dimension of the natural world: the heights of the world’s forests.

Michael Lefsky, an expert in remote sensing from Colorado State University in Fort Collins, used NASA satellites to compile a map that displays the height of all the world’s forest canopies. “The goal [of the research] was two-fold: to create a map that would allow us to map above-ground biomass, and simply to show that it can be done,” Lefsky says.
