Lefsky based the map on data from more than 250 million laser pulses collected during a seven-year period. Because each pulse returns information about a tiny portion of the surface, lidar offered ...

The map depicts average height over 5 square kilometers (1.9 square miles) regions), not the maximum heights that any one tree or small patch of trees might attain.

By using a satellite that fires the Earth with laser pulses from space, a researcher in the US has created the first global map of forest height. It is hoped that the project can improve climate ...

Measuring Forest Height Using Satellite DataEvery now and then, a new map changes the way we view our planet. This is one of those maps. The map above shows the height of Earth’s forests, from ...
