NASA Earth Observatory\u2019s map of Earth\u2019s forest canopy height<\/a> is based on estimates from a deep-learning model applied to Sentinel-2 optical data.<\/p>\n

According to a research team<\/a> led by Nico Lang of the EcoVision Lab<\/a> at ETH Z\u00fcrich, only 5 percent of the Earth\u2019s land area in 2020 was covered with trees standing taller than 30 meters.<\/p>\n

Lang, together with colleagues Konrad Schindler and Jan Wegner, produced the map by merging lidar data from NASA\u2019s Global Ecosystem Dynamics Investigation<\/a> (GEDI) mission with optical imagery from the European Space Agency\u2019s Sentinel-2 satellites<\/a>. GEDI\u2019s lidar profiles give detailed canopy heights<\/a>, but the profiles cover limited areas; Sentinel-2 optical data has abundant coverage, but it is not designed to measure canopy height. The researchers used the GEDI data to train a deep-learning model<\/a> capable of estimating canopy heights from Sentinel-2 images anywhere on Earth.<\/p><\/blockquote>\n
