Drone derived orthomosaic and surface models of the Casey Station Biopiles and EPH Excavations Dec 2021 to March 2022

This data package includes orthomosaics, digital surface models, and some derived layers (e.g. elevation contours) produced using structure from motion (sfm) from drone (Uncrewed Aerial Vehicle, UAV; Remotely Piloted Aircraft System, RPAS) imagery.The time series consists of 11 discrete data packages, acquired on 10 different days between the 17th of December 2021 and the 10th of March 2022. RGB photos were acquired with a DJI Phantom 4 quadcopter and a DJI M300 quadcopter, to track on-ground remediation activities during this time period. MethodsThe time series consists of 11 discrete data packages, acquired on 10 different days between the 17th of December 2021 and the 10th of March 2022. RGB photos were acquired with a DJI Phantom 4 quadcopter and a DJI M300 quadcopter, to track on-ground remediation activities during this time period. Data was collected by remediation team members, primarily Dr Rebecca McWatters. Data was processed in ESRI SiteScan, using the Pix4D Engine, by Dr Dan Wilkins. All processing reports have been included in this data package

本数据包包含正射影像镶嵌图（orthomosaics）、数字表面模型（digital surface models），以及部分通过运动恢复结构（structure from motion, SfM）技术由无人机（Uncrewed Aerial Vehicle, UAV；遥控航空器系统Remotely Piloted Aircraft System, RPAS）影像生成的衍生图层（例如高程等值线）。
该时间序列包含11个独立数据包，采集于2021年12月17日至2022年3月10日期间的10个不同日期。所用RGB影像由DJI Phantom 4四旋翼无人机与DJI M300四旋翼无人机采集，用于追踪此时间段内的地面修复活动。
