Quaternary surface ruptures surveyed with SfM, Panamint Valley, CA

To identify and map regions of distributed faulting in late Holocene alluvium, we generated 20 high-resolution (0.5 cm), 0.16 km2 structure-from-motion digital surface models using drone-based imagery. These data were collected, as part of a Master’s thesis, to resolve regions that lacked existing lidar coverage, and regions where small (0.5 - 1 m) offsets in young alluvium are poorly resolved by existing 0.5 m NCALM lidar DEMs (Figures 1-2). Data were collected at eight locations, over the course of three field seasons between March – November 2021. Each survey location (Figure 2) was given a unique name identifier based on the region and the survey takeoff/return point: 1) Mama Scarp Wash (MSW), 2) Central Alluvial Fan Wasteland (CAFW), 3) Carbonate Hill (CH), 4) Radio Tower Southeast (RTSE), 5) Radar Tower East (RTE), 6) Radar Tower North (RTN), 7) Radar Tower Southwest (RTSW), and 8) Radar Tower West (RTW). Each survey was collected using a DJI Phantom IV drone, including 6 - 8 targets of known dimensions and locations within the surveyed region, located using an EMLID Reach differential GPS. All surveys were collected using predetermined flight plans and parameters, programmed with DroneDeploy. For DroneDeploy specifications, see “Survey Methods” section within the metadata document.
