    Images were collected using a remotely piloted unoccupied aerial system over the bluffs of the eastern shore of Lake Michigan in St. Joseph rural residential area, Allegan County, MI. The digital imagery was collected with the internal camera of a DJI Phantom 3 PRO for 2019 data and DJI Phantom 4 PRO for 2021 data that was operated by the University of Toledo. on July 13, 2021. They cover an extent between the intersection of Lakeshore Dr. with Lakeshore Road to the north, and South Lakeshore Dr. to the south. Images were collected to monitor active bluff erosion in the area. The images are presented here in zipped files grouped by type of collection, nadir and oblique. The images were collected in .jpg format with red, green, blue (RGB) information and include Exif metadata with GPS date, time, and latitude and longitude, and other fields. These files were used in structure-from-motion (SfM) processing to obtain georeferenced 3D data.
