Imagery was collected at close to low tide on five 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 be 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 U.S. Geological Survey Coastal/Marine Hazards and Resources Program and conducted under U.S. Geological Survey field activity numbers 2016-013-FA, 2016-043-FA, 2016-053-FA, 2016-054-FA and 2016-055-FA. Purpose: This dataset consists of lists of image filenames with their corresponding locations. Each .zip file of images has a listing of the positions at which the photographs were taken. Supplemental_Information: For more information about the field activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-053-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-0054-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-055-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-013-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-043-FA. Drone mapping was conducted at Town Neck Beach in Sandwich, Massachusetts between 2015 and October 2017. The digital images, Ground Control Points and transect data from a calendar year are released together. This product contains the data collected in 2016.

Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Christopher Sherwood Contact_Organization: U.S. Geological Survey Contact_Address: Address_Type: mailing and physical address Address: 384 Woods Hole Road City: Woods Hole State_or_Province: MA Postal_Code: 02543-1598 Contact_Voice_Telephone: 508-548-8700 x2269 Contact_Electronic_Mail_Address: csherwood@usgs.gov Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The location information from the UAS navigation system was extracted from the EXIF headers in the geotagged images using a custom python progrm and saved in a plain-text comma-separated-value (.csv) file for easier reference. Logical_Consistency_Report: There is one list of file names, locations, and altitudes per zipped file of images. Images in each zip file represent all or a fight segment from a one day survey. 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: The data is complete for each field activity. 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 were written to the EXIF header portions of the images during flight. Horizontal coordinates for the Airshark hexacopter were derived from the GPS on the UAS, but written to the EXIF headers in a post-processing step, and described in the metadata for the images. 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 UAS were written to the EXIF header portions of the images during flight. Horizontal coordinates for the Airshark hexacopter were derived from the GPS on the UAS, but written to the EXIF headers in a post-processing step, and described in the metadata for the images. 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. In the .csv file names, the pilot's initials follow this string. When there is more than one zip file of images on a day there may be 'nadir' or 'oblique' to specify the camera orientation or '_f1', '_f2', indicates flight number. Each file has a different number of data records corresponding to the number of images in each .zip file: 2016013FA_U018_AS_f1_image_locations.csv has 125 lines; 20166013FA_U018_AS_f2_image_locations.csv has 158 lines; 20166013FA_U018_AS_f3_image_locations.csv has 152 lines; 20166013FA_U018_AS_f4_image_locations.csv has 126 lines; 20166013FA_U018_PTnadir_image_locations.csv has 29 lines; 20166013FA_U018_PToblique_image_locations.csv has 460 lines; 20166043FA_U019_AS_f1_image_locations.csv has 134 lines; 20166043FA_U019_AS_f2_image_locations.csv has 160 lines; 20166043FA_U019_AS_f3_image_locations.csv has 154 lines; 20166043FA_U019_AS_f4_image_locations.csv has 110 lines; 2016053FA_U015_PT_image_locations.csv has 898 lines; 2016053FA_U015_SM_image_locations.csv has 392 lines; 2016054FA_U016_PT_image_locations.csv has 859 lines; 2016055FA_U017_PTnadir_image_locations.csv has 453 lines; 2016054FA_U017_PToblique_image_locations.csv has 21 lines Entity_and_Attribute_Detail_Citation: USGS Field Activities 2016-053-FA, 2016-054-FA, 2016-055-FA, 2016-013-FA, and 2016-043-FA Distribution_Information: Distributor: Contact_Information: Contact_Organization_Primary: Contact_Organization: U.S. Geological Survey - ScienceBase Contact_Address: Address_Type: mailing and physical address Address: Denver Federal Center, Building 810, Mail Stop 302 City: Denver State_or_Province: CO Postal_Code: 80225 Contact_Voice_Telephone: 1-888-275-8747 Contact_Electronic_Mail_Address: sciencebase@usgs.gov Resource_Description: This data release includes raw data in the form of image locations extracted from the images collected on each day of operations.
