Imagery was collected at close to low tide on seven days to observe changes in beach and dune morphology. The images were geolocated by using the single-frequency geographic positioning system aboard the UAS. Ground control points (GCPs) were established by using temporary targets on the ground, which were located by using a real-time kinematic global navigation satellite system (RTK-GNSS) base station and rovers. The GCPs can be used as constraints during photogrammetric processing. Transect points were collected by using the same RTK-GNSS system; these can used to evaluate photogrammetric products. This data release includes georeferenced images, image-location files, GCPs, and transect points. Collection of these data was supported by the USGS Coastal and Marine Geology Program and were conducted under USGS field activity numbers 2017-005-FA, 2017-008-FA, 2017-010-FA, 2017-014-FA, 2017-027-FA, 2017-029-FA, and 2017-050-FA. Purpose: This dataset consists of lists of image filenames with their corresponding locations. This enables users to plot image locations without having to extract the information from the image headers. Supplemental_Information: For more information about the field activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-005-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-008-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-010-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-014-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-027-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-029-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-050-FA. Drone mapping was conducted at Town Neck Beach in Sandwich, Massachusetts between 2015 and the present (November 2017). The digital images, Ground Control Points and transect data from a calendar year are released together. This product contains the data collected in 2017.

Logical_Consistency_Report: There is a file for each field activity of surveying. Positions in the file have horizontal coordinates in decimal latitude (WGS84, positive north), decimal longitude (WGS84, positive east), and altitude (meters above sea level). The altitude information is susceptible to uncorrected offsets in the take-off altitude and may be biased by as much as 50 meters. Completeness_Report: These files contain a record for every image distributed as part of the larger work citation. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal coordinates (decimal degrees WGS84) recorded by the single-frequency GPS on the DJI Phantom 3 and Phantom 4 UAS were written to the EXIF header portions of the images during flight. For the other UAS, horizontal positions determined by the GPS were recorded in flight logs and transcribed to the EXIF headers during post-flight processing (geotagging). Horizontal locations are considered accurate to approximately 3 meters, but may be off by as much as 10 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical coordinates (meters above sea level) recorded by the single-frequency GPS on the DJI Phantom 3 and Phantom 4 UAS (flghts before May 4) were written to the EXIF header portions of the images during flight. For the other UAS, vertical positions determined by the GPS were recorded in flight logs and transcribed to the EXIF headers during post-flight processing (geotagging). The altitude measurements are accurate to approximately +/- 10 m, but uncorrected offsets in the take-off altitude may introduce biases of as much as 50 meters.

Each file contains one header line, followed by lines with 4 columns of comma-separated values. The header line describes the column contents, as follows: file name, latitude (decimal degrees), longitude (decimal degrees), altitude (meters). Subsequent lines contain the file names and locations at which the image was taken based on the GPS position from the UAS. The listing file names match the first fourteen characters of the name of the zipped images. When there is more than one zip file of images on a day the additional '_f1', '_f2', is appended to the list file name. Each file has a different number of data records corresponding to the number of images in each .zip file; the number of lines (below) includes the header line: 2017005FA_U020_image_locations.csv has 1042 lines; 2017008FA_U021nadir_image_locations.csv has 910 lines; 2017008FA_U021oblique_image_locations.csv has 50 lines; 2017010FA_U022nadir_image_locations.csv has 1017 lines; 2017010FA_U022oblique_image_locations.csv has 49 lines; 2017014FA_U024_image_locations.csv has 476 lines; 2017027FA_U029_image_locations.csv has 895 lines; 2017029FA_U031_f1_image_locations.csv has 441 lines; 2017029FA_U031_f3_image_locations.csv has 358 lines; 2017029FA_U031_f4_image_locations.csv has 392 lines; 2017029FA_U031_f5_image_locations.csv has 279 lines; 2017029FA_U031_f6_image_locations.csv has 343 lines; 2017029FA_U031_f7_image_locations.csv has 464 lines; 2017029FA_U031_f8_image_locations.csv has 347 lines; 2017050FA_U039_f1_image_locations.csv has 366 lines; 2017050FA_U039_f2_image_locations.csv has 188 lines; 2017050FA_U039_f3_image_locations.csv has 357 lines; 2017050FA_U039_f4_image_locations.csv has 241 lines; 2017050FA_U039_f6_image_locations.csv has 275 lines; 2017050FA_U039_f7_image_locations.csv has 373 lines 2017050FA_U039_f8_image_locations.csv has 393 lines; 2017050FA_U039_f9_image_locations.csv has 262 lines; 2017050FA_U039_f10_image_locations.csv has 383 lines; 2017050FA_U039_f11_image_locations.csv has 257 lines.
