Description
This dataset provides supporting evidence for a method of generating geometrically accurate orthophoto mosaics of paleoseismic trenches using physical scale bars printed with coded targets. These data accompany a forthcoming study by Delano et al., 2021, "Quick and dirty (and accurate) 3-D paleoseismic trench models using coded scale bars." The data constrain three-dimensional models of a 46-m long, narrow trench excavation across the Teton fault (Wyoming, USA).
