Pickle Pond pre-restoration orthomosaic and elevation products, Superior, Wisconsin, September 2022

The orthomosaic, digital surface model and point cloud presented here document conditions at Pickle Pond in Superior, Wisconsin in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights were approximately 400 feet above the surface of the lake water. Data were processed using structure-from-motion techniques to generate a point cloud (.las), digital surface model (DSM; .tif) and an orthomosaic (.tif) for the site. Products provide baseline information about terrestrial and emergent wetland communities against which to compare changes following restoration. Ground control points used to georeference the imagery and elevation products are provided as a .csv file, along with a processing report generated by the structure-from-motion processing software.

本数据集收录的正射影像镶嵌图（orthomosaic）、数字表面模型（digital surface model, DSM）与点云（point cloud）数据，完整记录了2022年9月美国威斯康星州苏必利尔市皮克尔塘（Pickle Pond）在规划生态修复实施前的场地现状。
影像采集采用搭载GNSS GPS升级组件的3D Robotics Solo无人机、Mission Planner飞行规划软件，以及宾得理光GRII三波段数码相机传感器。
航拍作业的飞行高度约为湖面上方400英尺。
数据通过运动恢复结构（structure-from-motion）技术完成处理，生成了该场地的点云文件（.las格式）、数字表面模型（.tif格式）与正射影像镶嵌图（.tif格式）。
上述成果可为该场地的陆地与挺水湿地群落提供基准本底数据，用于后续对比生态修复后的场地变化。
用于对影像及高程产品进行地理配准的地面控制点以.csv格式文件提供，同时附带运动恢复结构处理软件生成的项目处理报告。
