Lidar Point Cloud Data of Nogahabara Sand Dunes, Alaska, September 2015
This dataset provides information needed to reproduce a digital model of the Nogahabara Dune Field located in interior Alaska. The Nogahabara Dunes represent one of three active inland dune fields found in Alaska today. In an effort to update geospatial coverage of the dunes lidar data was collected over Nogahabara Sand Dunes in September 2015 using a 1955 Cessna 180 aircraft equipped with a Riegl brand LMS-Q240i laser scanner. The scanner was set to 10,000 laser shots per second and a +/- 30 degree beam sweep and flown over the Koyukuk National Wildlife Refuge's Nogahabara sand dunes. The flight pattern was designed for 50 percent overlap between each adjacent swath to achieve 2 points per square meter over the entire coverage. The lidar scanner was rigidly attached to a OXTS brand Inertial+2 GPS/IMU unit, which was being fed by a Trimble R7 GPS receiver. The resultant survey achieved 1.4 points per square meter. Discrete-return point cloud data are available in the LAS format.
