These unoccupied aerial system (UAS, aka drone) data were collected to identify and monitor coastal change along the Lake Michigan shoreline. The orthomosaic, digital elevation model, and point cloud were derived from aerial images collected using a UAS flown at select Chicago Beaches managed by the Chicago Park District. The orthomosaic and digital elevation model are products of a bare earth classified point cloud. The data are georeferenced to NAD83(1986) UTM Zone 16 North meters and vertical coordinates in NAVD88 meters. The digital aerial images were acquired with a DJI Phantom 4 Pro 12-megapixel camera small unoccupied aerial system. Photogrammetry software with RTK-GPS acquired ground control and check points provided X, Y, and Z accuracy defined in the metadata documents and in the accompanying reports. All activities were conducted according to Federal Aviation Administration regulations and with the permission of the Chicago Park District.
