Six bluffs were surveyed 2-3 times each between 2016 and 2018 using a Faro Focus 3D terrestrial laser scanner (TLS) and four bluffs were surveyed once via photogrammetry from a DJI Phantom 4 UAV (uncrewed aerial vehicle). The photogrammetry data were turned into high-resolution topographic data using Structure-from-Motion (SfM) processing. Included in this data file are SfM surveys as point cloud and DEM data; TLS surveys as point cloud and DEM data; and ArcGIS project files with geomorphic change detection data. These include volumetric change over time using TLS data from 2016-2018 and comparisons of DEMs generated from TLS and SfM data collected on the same date at each site.
