Picture: 3D mapping of rainforests
In 2009, researchers with the Carnegie Institution, World Wildlife Fund, Amazon Conservation Association, and the Ministry of Environment, Peru used satellite images and airborne Light Detection and Ranging (LiDAR), together with field plots, to map aboveground carbon stocks and emissions at 0.1-ha resolution over 4.3 million ha of the Peruvian Amazon. To measure forest deforestation, degradation, and regrowth, the researchers collected 27 LiDAR survey areas covering a total of 514,317 ha were collected throughout the 4.3 million ha region, at a spatial resolution of less than one meter.
