Harvard Forest Symposium Abstract 2013
- Title: LiDAR Biomass

- Abstract:
Airborne and Terrestrial Scanning Light Detection and Ranging (LiDAR) data from several field campaigns over Harvard Forest is now available to allow comparison of canopy height models (CHM). In August 2012 the National Ecological Observatory Network (NEON) flew the Airborne Observation Platform (AOP) over Harvard Forest. Mounted on the AOP is both a hyperspectral imager, and a full waveform 1064nm Optech LiDAR. Discrete returns from this instrument have been used to develop both 1m and 0.5m resolution Canopy Height Models (CHM). In June 2012, the National Aeronautics and Space Administration (NASA) flew Goddard’s LiDAR, Hyperspectral, and Thermal (G-LiHT) instrument package over Harvard Forest. Using discrete 1550nm LiDAR, a 1m resolution CHM was derived for areas overlapping NEON’s. In July 2009, the terrestrial full waveform 1064nm Echidna Validation Instrument (EVI) was deployed at several hectare-sized locations in Harvard Forest. The point clouds were used to reconstruct 3D canopy simulations. During both the 2009 and 2012 field campaigns, extensive field forestry measures were also collected. Herein the NEON and G-LiHT 1m resolution CHM are compared. In addition, a CHM derived from the EVI scans are compared to the 0.5m resolution NEON CHM.
