Topography of Normal Faults in the Volcanic Tablelands, CA 2019

Welcome Guest ( Sign In )

Overview

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.

Platform: Structure from Motion / Photogrammetry

Survey Area: 4 km²

Raster Resolution: 0.04 meter
Orthophoto Resolution: 0.02 meter

Survey Date: 04/11/2019 - 04/13/2019
