Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in Ludington, MI, July 11, 2019, and July 14, 2021

Metadata Updated: July 6, 2024

Images were collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in Ludington rural area, Mason County, MI. Images were collected in two separate surveys conducted on July 11, 2019, and July 14, 2021, using a DJI Phantom 3 and 4 PRO commercial UAS respectively 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 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 default 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 classified in never classified (class 0), ground (class 2), medium vegetation (class4), an water (class 9).
