(C) Aerial view of the drone flight. (D–I) Some relevant footprints from the outcrop. All scale bar: 5 cm. (D) M2020-02. (E) M2020-06. (F) M2020-05. (G) M2020-11. (H) M2020-74. (I) M2020-35. The map in (B) was created using Adobe Photoshop Versión: 9.0 (https://adobe-photoshop-9-cs2.en.lo4d.com/) based on the photogrammetric orthomosaic (C) produced using Pix4DMapper© (versión PIX 4D Cloud, https://www.pix4d.com/). (C) was obtained by a low-altitude programmed flight using an Unmanned Aerial Vehicle (UAV) on June the 6th, 2020, 12 AM UTC. A multirotor DJI Phantom 4 + with a 4 k 20 Mpix RGB CMOS camera was collected at an average height of 7 m above the ground photographs over the study area (564 m2).
