A global dataset of tree canopy height derived from remote sensing data, this raster dataset includes classes for canopy height (up to 30m), as well as classes for ice/snow and water. 

Note: Tree height over cities and suburbs may be confounded with building height, as this dataset does not discriminate between the height of vegetation and man-made objects.
