Description:
Abstract:
Low-altitude (30-120 meters above ground level) digital images of Town Neck Beach in Sandwich, Massachusetts, were obtained with a series of cameras mounted on small unmanned aerial systems (UAS, also known as a drone). 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 overlapping aerial images obtained on March 30, 2016 that can be used with photogrammetric processing software to create point clouds, digital elevation models, and orthophoto mosaics.
Supplemental_Information:
For more information about this field activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-013-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.

Attribute_Accuracy_Report:
Two different UAS were used. One system was a DJI Phantom 3 quadcopter operated by P. Traykovski with a DJI FC300X camera that acquired photos 4000 x 3000 pixels (12 megapixels), with file sizes generally between 4.5 and 6.5 MB on disc, depending on image complexity. The other system was a custom hexacopter with a Sony NEX-5R camera that acquired photos 4912 x 3264 pixels (16 megapixels), with file sizes between 6 and 13 MB, depending on image complexity. Time stamps were recorded in the EXIF portion of the images taken with both systems and, in addition, the GPS coordinates were written to the EXIF portion of images taken with the DJI system. GPS locations were added to the EXIF portion of the Airshark images as a post-processing step. The GPS used on both of the UAS has practical accuracies of 3 meters horizontally and 10 m vertically, and the time stamps are accurate to better than 1 millisecond. However, for the DJI system, the altitudes recorded in the EXIF portion of the image metadata include uncorrected offsets and may be biased by as much as 250 m. The relative altitudes stored in the XMP portion of the image metadata are accurate to +/- 10 m.
Logical_Consistency_Report:
All images were acquired by either the DJI FC300x camera on the DJI Phantom3 quadcopter, or by the Sony NEX-5R camera on the Airshark hexacopter. Images were collected along pre-planned lines with 50 to 60% cross-track overlap. The camera was set to record images with 65 to 70% along-track overlap. Flight lines were oriented approximately northwest/southeast, roughly parallel to the shoreline. Flights lasted the duration of the UAS battery life (maximum about 22 minutes) or until the flight was completed or aborted. Photographs were renamed to include survey ID, Camera ID, flight ID, date and time, and original filename to ensure no duplicated filenames.
Completeness_Report:
UAS flights were conducted to map Town Neck Beach in Sandwich, MA on March 30, 2016. Gaps in sequential photos exist because some photos were deleted because, for example, of overexposure, or to avoid multiple photos of the landing pad as the UAS was taking off and landing. GPS times were not recorded by the DJI firmware or in the post-processing geotagging performed for the Airshark images, but the local times in the EXIF tag "DateTime" are accurate.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal positions recorded by the UAS GPS were written directly into the EXIF portion of the images during the flights. The GPS on the UAS provided horizontal locations are considered accurate to approximately 3 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical positions recorded by the UAS GPS were written directly into the EXIF portion of the images during the flights. The GPS on the UAS provided vertical locations are considered accurate to approximately 10 meters.

These JPEG images were collected by one of two unmanned aerial system (UAS). One was a DJI Phantom 3 quadcopter with an integrated DJI FC300X camera. this camera acquired photos 4000 x 3000 pixels (12 Megapixels). The camera orientation for most of these flights was near nadir, aimed directly below the UAS. The last 29 images were oblique, taken with the camera oriented 30 degrees from vertical. The second UAS was a custom design with six-rotors operated by Airshark LLC (https://are-corp.com/about-us/) with a Sony Nex-5R camera. The images collected by Airshark are 4912 x 3264 Pixels (16 Mpixels), with file sizes generally between 6 and 13 MB on disc, depending on image complexity. The camera orientation for all Airshark flights was nadir, aimed directly below the UAS. The images from each UAS are distributed in separate .zip files. For the DJI images, horizontal positions and elevations were recorded in the UAS onboard navigation and applied to the images during the flight. For the Airshark images, the record of horizontal and vertical positions was downloaded from the GPS and timing was used to infer the location of each image. This location was written to the EXIF portion of the images by the vendor (Airshark LLC) before the images were provided to the USGS. These JPEG images may be used with photogrammetric software to produce geolocated point clouds, digital elevation models, orthophoto mosaics, and other products.
Process_Step:
Process_Description:
Two UAS were flown to acquire these images; one owned and flown by Peter Traykovski, the other owned and operated by Airshark LLC. The DJI images were geotagged in flight by the UAS. The Airshark images were geotagged by Ian Ray of Airshark immediately after the flights and provided to the USGS as geotagged images. Both used local time, so an adjustment to GMT was made (see first parameter of step 1 below). They were also processed to add USGS required information to the EXIF headers and renamed to unique file names. These steps are described here:
1. ExifTool (https://www.sno.phy.queensu.ca/~phil/exiftool/, version 10.75) was used to add required attribution tags to all the photos. The command used to update the tags was: exiftool -AllDates+=4 -CopyrightNotice="Public Domain - please credit U.S. Geological Survey " -ImageDescription="Photographs of Town Neck Beach, Sandwich, Massachusetts, USA from survey 2016-013-FA " -Caption-Abstract="Town Neck Beach, Sandwich, Massachusetts, USA from survey 2016-013-FA " -Caption="Town Neck Beach, Sandwich, Massachusetts, USA from survey 2016-013-FA " -sep ", " -keywords="Town Neck Beach, Sandwich, Massachusetts, 2016-013-FA, UAS, aerial imagery, USGS " -comment="Photo from down-looking UAS camera during survey 2016-013-FA." -Credit="U.S. Geological Survey" -Contact="WHSC_data_contact@usgs.gov " -Artist="Peter Traykovski" (or "Airshark") *.JPG
2) All the JPEG images were renamed with Namexif (version 1.7, http://www.digicamsoft.com/softnamexif.html) to ensure unique filenames and compliance with USGS Coastal/Marine Hazards and Resources Program's best practices for image naming convention. Images were renamed with a survey ID prefix followed by a local USGS UID, which corresponds to a distinct UAS project; a camera ID that distinguishes among the cameras by make, model, and camera number; the image acquisition date and coordinated universal time (UTC) in ISO8601 format; and a suffix with the original image name. For example, in this image name '2016013FA_U018AS5R_20160330T145026Z_DSC05859.JPG', 2016043FA is the survey ID, U019 is the internal identifier code, AS5R is the internal camera ID for the Airshark UAS camera, 20160330 is the UTC date in format YYYYMMDD. A 'T' is used to separate date from UTC time in format HHMMSS followed by a Z (for Zulu), and 'DSC05859.JPG' is the original raw photo name appended to the end of the new filename. For images taken by the DJI Phantom 3, the camera ID is 'DJP3'.
