Airborne LiDAR of Meteor Crater and the Surrounding Landscape
In March 2010, prompted by a proposal by Marisa Palucis of the University of California Berkeley, the National Center for Airborne Laser Mapping (NCALM) obtained aerial LiDAR data of Meteor Crater. The survey was conducted with an Optech GEMINI Airborne Laser Terrain Mapper mounted on a twin-engine Piper PA-31. The crater rim, walls, and interior were surveyed with a point density of 5 pts/m2, while the surrounding terrain was surveyed with a point density of 8 pts/m2, at a flight altitude of 600 m. The total area surveyed is 34.4 km2 and the total mapping time was 4.16 hours. Additional details are available in the NCALM Mapping Project Report.
These data were collected by Marisa Palucis through the NSF-sponsored National Center for Airborne Laser Mapping (NCALM).

The datasets below were collected from the NSF Open Topography Facility website (http://www.opentopography.org/).
Point Cloud DataThe Point Cloud dataset contains X,Y, Z data values for each of the 148,006,004 LiDAR data points acquired within a 5 km x 5 km region centered in Barringer Meteorite Crater. The data points were collected at a density of 8 pts/m2 for the crater rim and walls and at 4 pts/m2 for the surrounding area. The Point Cloud dataset was saved in LAS and LAZ formats.
The Gridded datasets contain values from the Point Cloud data that have been gridded for a 5 km x 5 km collection area centered on Barringer Meterorite Crater. The gridded datasets were sampled at 1 meter resolution and saved in GeoTiff format.
