Structure-from-Motion photos and derived point clouds from bluffs in Miami Park, MI, July 19, 2021

Images were collected using a remotely piloted unoccupied aerial system over the bluffs of the eastern shore of Lake Michigan in Miami Park rural residential area, Allegan County, MI. Images were collected on July 19, 2021, by Richard Becker, University of Toledo, and cover an extent between south of Lakestone Dr. to the north, and south of A St. 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 and include Exif metadata with GPS date, time, longitude and latitude, copyright, keywords, and other fields. These files were used in structure-from-motion (SfM) processing to obtain georeferenced 3D point data. The 3D derived data are in open source lidar data exchange las format and were created from the collected images using SfM photogrammetry software.
