The data collection was funded by the National Science Foundation (NSF) and performed by the National Center for Airborne Laser Mapping (NCALM) during peak leaf-on and leaf-off conditions in 2010 (July 2010 and December 2010, respectively). The dataset contains point cloud tiles in LAS format, 1 m Digital Surface Model (DSM) derived using first-stop points, 1 m Digital Elevation Model (DEM) derived using ground-class points and 1 m hill shade dataset derived from DEM. These datasets were used to estimate vegetation biomass and distributions, provide bare earth elevations, and to assist with prediction of Critical Zone creation and structure.<p><br>Publications associated with this dataset can be found at <a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM's Data Tracking Center</a></p> National Center for Airborne Laser Mapping https://ncalm.cive.uh.edu/ originator National Science Foundation https://nsf.gov/ resourceProvider Susquehanna Shale Hills Critical Zone Obervatory http://criticalzone.org/shale-hills/about/ custodian University of California, Merced https://www.ucmerced.edu/ custodian null info@opentopography.org https://opentopography.org distributor en geoscientificInformation -78.0911390395946 -77.8413148545572 40.5607831627591 40.735997581475 https://doi.org/10.5069/G9VM496T HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
