Overview

ASU logo

This dataset contains high resolution topography and orthomosaic imagery along three normal fault scarps in the Volcanic Tablelands near Bishop in Eastern California. In the Volcanic Tablelands, normal faults create prominent scarps that offset the Bishop Tuff. This area has been the focus of a number of studies on fault zone structural geology and geomorphology.

Data was collected via uncrewed aerial vehicle (UAV) imagery over three fault scarps each with length of 2-4 km. Data products include: point clouds, digital surface models (DSMs), and orthomosaics using structure-from-motion (SfM) techniques.
