A LiDAR data set for Meteor Crater, Arizona is publicly available via the OpenTopography facility at the San Diego Supercomputer Center. The data were collected in March 2010 by the National Center for Airborne Laser Mapping (NCALM) with NSF funding.
The survey area is a rectangular polygon, roughly 5.44 km on a side, enclosing the Barringer Meteorite Crater and its ejecta blanket. The project area is located 60 km southeast of Flagstaff, AZ and 30 km west of Winslow, Az. The polygon has a surface area of 29.7 km2; the requirement indicates two point densities one for the crater walls and rim of 8 pts/ m2, and one for the surrounding area of 4 pts/m2.
