Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in St. Joseph, MI, July 8, 2019 and July 13, 2021

Images were collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in St. Joseph rural residential area, Berrien County, MI. Images were collected in two separate surveys conducted on July 8, 2019, and July 13, 2021, using a DJI Phantom 3 and 4 PRO commercial UAS respectively operated by the University of Toledo. The images cover an extent between the intersection of Lakeshore Dr. with Lakeshore Road to the north, and South Lakeshore Dr. to the south. The purpose of the survey was 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, 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 compressed lidar data exchange laz format and were created from the collected images using SfM photogrammetry software. A description of the laz format and links to software tools for using laz files are provided at the USGS website: https://www.usgs.gov/news/3d-elevation-program-distributing-lidar-data-laz-format.The point cloud was not classified.
