US: EarthDefine has created comprehensive tree datasets that consistently map the location of all trees and tree heights across Ohio and Pennsylvania in detail. The new 1m resolution datasets will enable multiple applications for land management and quantification of the ecosystem services provided by trees. The company used terabytes of color infrared imagery obtained in the summer of 2010 and 2013 along with 3D point cloud data from LiDAR flown between 2006 and 2014, to create the statewide tree cover datasets. One good thing about these new datasets is that they bridge the gaps between high resolution datasets that cover coarse-grained national tree canopy data sources like the National Land Cover Database.
