The UAV images were obtained in RAW format during the flight and converted to JPEG format in the Digital Photo Professional version 3.13.0.1 (Canon Inc.) software. The images were then processed into an orthophoto with a resolution of 0.04 m and a dense 3D point cloud in the original WGS84 coordinate system. The Agisoft Photoscan Professional software Version 1.3.2 build 4205, 64 bit (Agisoft LLC.) and the structure from motion (SfM) algorithm were used to create these data. Agisoft software estimates internal and external camera orientation parameters during photo alignment. This estimation is performed using only image data, and therefore, there may be some errors in the final estimates. The accuracy of the final estimates depends on many factors, such as overlap between the neighboring photos, as well as on the shape of the object surface. These errors can lead to nonlinear deformations of the final model.
