Images were collected in four separate instances on July 9, August 10, September 1, and October 18, 2019 and cover similar extent. Images were collected to monitor active bluff erosion in the area. The images are presented here in zipped files grouped by month and collection. The images were collected in jpg format and include Exif metadata with GPS date, time, and latitude and longitude, copyright, keywords, and other fields. These files were used in structure-from-motion (SfM) processing to obtain georeferenced 3D data. The 3D derived data is in las format and were created from the collected images using SfM photogrammetric software. Images were collected to monitor active bluff erosion in the area. The 3D point clouds were produced to determine the accuracy, precision, and effectiveness of assessing bluff landslides.

For 3D derived files, Agisoft Metashape 1.5.5 was used, the files have the date of acquisition in their name and are in las format and are between 1 and 3.5 GB each. The horizontal and vertical accuracies of the surface models were compared against GPS survey data of known features covered by the survey. All data fall within expected ranges. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. SfM-based measurements of ground conditions were within 10 cm of the total uncertainty of the field-based GPS measurements. SfM-based root mean square error (RMSE) measurements vary by date of collection from 6 cm to 27 cm.
