3D Point Cloud - Retroculus Island, Xingu River, Brazil

Dense 3D point cloud stored in .las format of Retroculus Island from the Xingu River in Brazil. The point cloud is generated at a ground sampling distance of 1.43 cm. A DJI Inspire 1 with an X3 camera were used to collect the photographs on August 8, 2016. The photographs were processed with Pix4D Mapper Pro through a Structure from Motion Multiview Stereo workflow as described in:<br>Kalacska, M.; Lucanus, O.; Sousa, L.; Vieira, T.; Arroyo-Mora, J.P.
