A good review of remote tree sensing and not just lidar.

"Other remote sensing methods can fill out the picture. Lidar, which typically bounces pulses from an airborne laser off the terrain below, can determine topography and the height of vegetation. (Recently, a lidar sensor was added to the International Space Station.) Based on tree heights obtained through lidar and light reflected from the plants back to a plane or satellite, Schaepman’s team can calculate a forest’s biomass. The researchers have also developed computer models that predict forest productivity based on changes in biomass and in the biochemical composition of the plants. And they have confirmed that satellite-borne sensors measuring long IR wavelengths can track the effects of drought. Plants normally cool their leaves by transpiring water; when they run short, their leaf temperature rises."

I can see the benefits of such projects, but then again, I also see the negatives of what "forest productivity" can mean to one person than to another.
