Lidar point density varied from 2 to >10 returns per m² with an average of about 5 returns per m². Vertical and horizontal accuracies are estimated to be 0.07 m and 0.03 m, respectively. The lidar coverage comprises roughly 3600 km² with includes the bottoms and sides of Taylor, Pearse, Wright, Victoria, Mckelvey, Barwick, and Valham valleys, Bull Pass, in addition to other ad hoc regions nearby including the Pegasus flight facility and two regions on Ross Island, McMurdo Station/Scott Base (and surroundings), and the coastal margin between Cape Royds and Cape Evans.<br><br>A detailed description of the survey can be found in the Earth System Science Data publication <a href="https://doi.org/10.5194/essd-9-435-2017">High-resolution elevation mapping of the McMurdo Dry Valleys, Antarctica, and surrounding regions</a> (Fountain et al., 2017).<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 null info@opentopography.org https://opentopography.org distributor en geoscientificInformation 160.105465709427 166.95825154803 -78.282528025863 -77.2119047443454 https://doi.org/10.5069/G9D50JX3 HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
