Using a combination of satellite imagery, forest inventories, and supercomputer technologies, the international team of researchers was able to map tree populations worldwide at the square-kilometer level.

The supercomputer technologies requires some human input. So I believe there may be 15X more trees in the world than originally thought. Did they count the 11 trees I have planted in the last 5 years? I doubt they would show up on satalite.
