Description

Digital models of the surface (DSM) and terrain (DTM) derived from NEON LiDAR data. DSM: Surface features (topographic information with vegetation and man-made structures present). DTM: Bare earth elevation (topographic information with vegetation and man-made structures removed). Images are given in meters above mean sea level and mosaicked onto a spatially uniform grid at 1 m resolution.

See NEON Data Product DP3.30024.001 for more details.
