Iriri_HD.las

Dense 3D point cloud stored in .las format of the Iriri rapids from the Xingu river basin in Brazil. The point cloud is generated at a ground sampling distance of 1.46 cm. A DJI Inspire 1 with an X3 camera were used to collect the photographs on August 6, 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. Freshwater Fish Habitat Complexity Mapping Using Above and Underwater Structure-From-Motion Photogrammetry. <em>Remote Sens.</em> 2018, <em>10</em>, 1912.https://www.mdpi.com/2072-4292/10/12/1912/htm<br><br>Interactive version of the point cloud can viewed online at: http://bit.ly/iriri3D<br><br>

巴西兴谷河流域伊利里急流的致密三维点云，存储格式为.las格式。该点云的地面采样距离为1.46厘米。数据采集采用搭载X3相机的大疆悟1（DJI Inspire 1）无人机，拍摄日期为2016年8月6日。

所获照片通过Pix4D Mapper Pro软件，按照运动恢复结构多视图立体（Structure from Motion Multiview Stereo）流程进行处理，相关文献描述如下：Kalacska, M.; Lucanus, O.; Sousa, L.; Vieira, T.; Arroyo-Mora, J.P. 《采用水上与水下运动恢复结构摄影测量法开展淡水鱼类栖息地复杂性制图》. *Remote Sens.* 2018, *10*, 1912. 原文链接：https://www.mdpi.com/2072-4292/10/12/1912/htm
