A map of all the trees in the U.S.

by Laura Domela

This map is the result of years of research by NASA, the National Geological Survey, and the U.S. Forest Service. It shows, in staggering detail, the total of woody biomass (read trees) across these United States. Presenting the entire nation at a 30 meter resolution, with 4 pixels representing an acre land, it’s one amazing map. While impressive in its own right, this tree map aims to help keep a record of the amount of carbon being held in Earth’s plant matter. With concerns over carbon’s role in climate change, surveys like this are invaluable tools.
