Aerial imagery and photogrammetric products from unmanned aerial systems (UAS) flights over the Lake Ontario shoreline at Chimney Bluffs, New York, July 14, 2017

Low-altitude (80-100 meters above ground level) digital images were obtained from a camera mounted on a 3DR Solo quadcopter, a small unmanned aerial system (UAS), in three locations along the Lake Ontario shoreline in New York during July 2017. These data were collected to document and monitor effects of high lake levels, including shoreline erosion, inundation, and property damage in the vicinity of Chimney Bluffs State Park, New York. This data release includes images tagged with locations determined from the UAS GPS; tables with updated estimates of camera positions and attitudes based on the photogrammetric reconstruction; tables listing locations of the base stations, ground control points, and transect points; geolocated, RGB-colored point clouds; orthomosaic images; and digital elevation models for each of the survey regions. Collection of these data was supported by the Federal Emergency Management Agency, the State of New York Departments of State and Environmental Conservation, and the USGS Coastal and Marine Geology Program and was conducted under USGS field activity number 2017-042-FA.

2017年7月，研究团队于美国纽约州安大略湖沿岸三处点位，利用搭载于3DR Solo四旋翼无人机（小型无人机系统，Unmanned Aerial System, UAS）的相机，采集了地面海拔80至100米区间的低空数码影像。本次数据采集旨在记录并监测高湖水位所引发的各类影响，涵盖纽约州奇姆尼布拉夫斯州立公园周边的岸线侵蚀、水域淹没及财产损失情况。本次公开的数据包含：基于无人机全球定位系统（Global Positioning System, GPS）标注位置的影像文件；通过摄影测量重建得到的相机位姿更新估算表；列明基站、地面控制点与断面点位置的统计表；带有地理坐标的RGB彩色点云数据；正射影像；以及各调查区域的数字高程模型。本项数据采集工作由联邦紧急事务管理局、纽约州州务部与环境保护部、美国地质调查局（USGS）海岸与海洋地质项目资助，并依据美国地质调查局野外活动编号2017-042-FA实施。
