Collection Overview: The U.S. Geological Survey (USGS) Geologic Hazards Science Center (Golden, CO) coordinated the acquisition of ~198 square kilometers of airborne Light Distance and Ranging (Lidar) data and derivative bare-earth ground models to support active fault studies in the Northern Walker Lane (California-Nevada border). Faults surveyed include from west to east the Mohawk Valley, Grizzly Valley, Honey Lake, and Warm Springs Valley fault systems. Specifications for the acquisition followed recommendations made by R. Haugerud et al. in a proposed specification for lidar surveys in the Pacific Northwest ( 2008). The data were acquired by Airborne Solutions Inc. The vendor reported an average shot density of 15-17 points/m2 and the vendor delivered bare-earth and first-return digital elevation models with a cell spacing of 0.25 m2.  Project PI: Ryan Gold.
