This is a set of 642 primarily near-nadir aerial photogrammetric images and their derivatives, collected from the Elwha River, WA, with an intervalometer-triggered digital camera from a crewed light aircraft, for processing using structure-from-motion photogrammetry and machine learning to study coastal geomorphic processes, primarily during and after dam removal on the Elwha River, at high temporal and spatial resolution. JPG files in each folder follow the following naming convention: {YYYYMMDDHHMMSS}_{SN###}_{PreservedFileName}.jpg, where {YYYYMMDDHHMMSS} is the image acquisition time in {YearMonthDayHourMinuteSecond} expressed in 24-hour time, as recorded by the camera’s internal clock or subsequently adjusted and written to the DateTimeOriginal field in the image EXIF data, {SN###} is the last 3 digits of the camera serial number OR 000 in the case the camera doesn't have a serial number, preceded by the letters “SN”, and {PreservedFileName} is the original filename recorded at the time the image was captured. For example, 20120319123426_SN000_IMG_1082.JPG would be the filename for an image with a DateTimeOriginal EXIF time/date stamp of March 19th, 2012, at 12:34:26 pm in Pacific Standard Time (PST) - See attribute accuracy report in platform metadata for details on time accuracy.
