: Calhoun Critical Zone Observatory 2016 Leaf Off LiDAR Survey
: Airborne Lidar
The National Center for Airborne Laser Mapping (NCALM) conducted a lidar survey of the Calhoun Critical Zone Observatory (CCZO) area on February 26, 2016. The survey was funded by NSF award EAR-1339015; the Calhoun CZO is funded by NSF award EAR-1331846 (P.I. Daniel deB. Richter).
Note: Lidar and DEM data have been adjusted by -0.098 meters to adjust for systematic vertical bias determined by analysis of 1251 ground check points collected at the Spartanburg airfield using a vehicle-mounted GPS antenna and receiver.
