Data are collected and produced primarily for coastal monitoring using structure-from-motion photogrammetry. The intent is to develop and implement survey methods to study coastal geomorphic processes at high temporal and spatial resolution, and to make data available as rapidly as possibly while maintaining U.S. Geological Survey (USGS) Fundamental Science Practices (FSP) in the spirit of producing timely best science. Data products from the PCMSC PlaneCam data collection platform (DCP) are published in a directory structure with one folder per survey ("collect"), and within that folder, one folder per product. A process step or steps in metadata for each product describe naming conventions and methodology for each product. A detailed description of naming conventions can be found in the Entity and Attribute Overview and Process Steps of this metadata record. Purpose: These data are provided in an effort to record ground conditions at a high temporal and spatial resolution, and after high-magnitude disturbance events, to improve our understanding of earth surface processes (natural hazards) affecting coastal resources.

Camera EXIF position data are generally accurate to within at least a few hundred meters, and time data are accurate to within a few minutes. Camera clock was UTC through 7 March 2018, and switched to PST starting 29 March 2018 (to simplify processing across UTC date changes). Some images are over-exposed, some images are under-exposed, and no effort is made to optimize exposure through post-processing, nor to eliminate imagery with acquisition errors. These data represent raw imagery as-collected and subsequently used in Structure-from-Motion (SfM) photogrammetric processing workflows. GNSS position accuracy is limited by Precise Point Positioning (PPP) techniques and is assumed to be about 10cm horizontal and 15cm vertical based on post-processing reports, multiple comparisons with ground control points, and residual error after alignment for photogrammetry. Accuracy reports from each PPP post-processing report are included with GNSS data when published for a survey. Logical_Consistency_Report: RGB values are 8-bit, generally not saturated or underexposed. In a few cases of high or low light conditions, some imagery may be under- or over-exposed. GNSS values are checked for consistency and outliers. Bad data are discarded and missing data are interpolated or replaced with calculated positions from 4D SfM (see Over and others 2021 for methods). Completeness_Report: Data are considered complete for the information presented, as described in the abstract. Users are advised to read the metadata record carefully for additional details, and to examine EXIF data for individual flights and images if required to determine camera settings such as exposure mode and shutter speed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. Most images have EXIF stamps from a consumer-grade GPS, updated every few seconds. Position accuracy for these images is generally within about 200m. Some images may lack GPS position in EXIF data, but in most cases we apply interpolated positions or positions derived through onboard survey-grade GNSS or 4D structure-from-motion. High-precision positions are produced as a separate product for most flights during post-processing. Interpolated positions are a linear interpolation of XYZ coordinates between images with known coordinates. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A formal accuracy assessment of the vertical positional information in the dataset has not been conducted. Most images have EXIF stamps from a consumer-grade GPS, updated every few seconds. Vertical accuracy for these images is not assessed for accuracy. Some images may lack GPS position in EXIF data but in most cases we apply interpolated positions or positions derived through onboard survey-grade GNSS or 4D structure-from-motion. High-precision positions are produced as a separate product for most flights during post-processing. Interpolated positions are simply a linear interpolation of XYZ coordinates between images with known coordinates. Lineage: Process_Step: Process_Description: Acquisition -- Each image is acquired in camera raw format. Camera is triggered by an intervalometer, usually integrated with a survey-grade GNSS and triggered using a pulse-per-second (PPS) signal from the GNSS, routed through a microcontroller to the camera remote shutter, and recording an event mark to the GNSS when the shutter is actuated, through the flash-sync port on the camera. A consumer-grade GPS is typically attached to the camera keeping camera time synced with UTC time and providing approximate coordinates for EXIF data.
