The University of Texas at Dallas has been involved in digital mapping of outcrops and creation of 3D photorealistic models in the area of the Arbuckle anticline. In a prior survey in 2014, we mapped an area of the Arbuckle anticline which subsequently collapsed in 2015. We remapped it in the years 2015 and 2016. The uniqueness of these data obtained before the event provides enhancement of a database. This survey incorporates the use of terrestrial LiDAR, photogrammetry and satellite positioning systems in the mapping and evaluation of the geomorphic changes observed in the 2-year period from 2014 to 2016. A major factor in the analyses and monitoring of geomorphological and geological changes is the availability of previous and current data to determine the cause, nature and extent of these changes that have occurred over time. Studies have shown that terrestrial laser scanners such as LiDAR, a remote sensing technique, can be applied effectively to detect geomorphic changes. The point cloud data acquired from the terrestrial laser scanner were integrated with photogrammetry to reconstruct a high resolution photorealistic model of the 2014 terrain.
