Structure-from-Motion (SfM) point clouds were created from images collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in Ludington, MI, a rural natural area to assess land changes. The digital imagery was collected with the internal camera of a DJI Phantom 3 PRO for the July 11, 2019, data and DJI Phantom 4 PRO for the July 14, 2021, data that was operated by the University of Toledo. The images cover an extent between north of Chauvez Rd. to the south and north of W. Bradshaw Rd. to the north. The images were collected in .jpg format and include default Exif metadata with GPS date, time, latitude and longitude, and other fields. Point clouds were created from the collected images using Agisoft Metashape 1.7.6 SfM photogrammetry software and are provided in the open source compressed lidar data exchange LAZ format. The point clouds were classified into the following: never classified (class 0), ground (class 2), medium vegetation (class4), and water (class 9).
