Abstract
Bare earth data were derived from discrete return LiDAR data collected near the Toolik Field Station (AK) as part of the NASA funded Terrestrial Ecology Project NNX12AK83G, PIs: Lee A. Vierling (University of Idaho, Moscow, Idaho, USA), Jan U.H. Eitel (University of Idaho, Moscow, Idaho, USA), Natalie T. Boelman (Columbia University, New York City, New York, USA), and Kevin L. Griffin (Columbia University, New York City, New York, USA). The bare earth data were derived using the software package TerraScan. The spatial extend of the dataset is: -149.675381 (West bounding long); -148.853695 (East bounding long); 68.372569 (South bounding lat); and 68.756794 (North bounding lat). The dataset is discontinuous within this spatial extend covering the following five areas of Interest (AOIs)with approximate mile point locations on the Dalton Highway in parentheses: Roche Moutonnee Creek (263.9 miles), an unnamed site (288.8 miles), Toolik Field Station (284.3 miles), Imnavait (290.6 miles), and Sagavanirktok Department of Transportation (DOT) (305.6 miles). Data were collected August 1, 2013, with an approximate point density of 30 points/m2.
