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 February 11, 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=2016-055-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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The camera used on the UAS 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. Time stamps and GPS locations were recorded in the EXIF portion of the images. The GPS used on 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, 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 aerial photographs were acquired by with the integrated DJI FC300X camera mounted on a DJI Phantom 3 quadcopter unmanned aerial system (UAS). 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. The flight lines and camera shutter timing were planned to record images with 65 to 70% along-track overlap.
Completeness_Report:
UAS flights were conducted to map Town Neck Beach in Sandwich, MA on February 11, 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.
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. 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.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical positions recorded by the UAS GPS were written directly into the metadata (EXIF and XMP) portions of the images during the flights. The altitude measurements are accurate to approximately +/- 10 m, but uncorrected offsets in the take-off altitude introduced biases of as much as 250 meters in the EXIF tag "Absolute Altitude". The most accurate altitude information can be read from the "Relative Altitude", which is stored in the XMP portion of the image. These altitudes are accurate to approximately +/- 10 m.

These JPEG images were collected with an integrated DJI FC300X camera mounted on a DJI Phantom 3 quadcopter unmanned aerial system (UAS). The camera used on the UAS acquired photos 4000 x 3000 pixels (12 megapixels). The camera orientation for most of flights was near nadir, aimed directly below the UAS. THe last 20 images were taken with the camera mounted obliquely, approximately 30 degrees forward from vertical. Horizontal positions and elevations were recorded in the UAS onboard navigation and applied to the images during the flight. 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:
A DJI Phantom 3 quadcopter UAS flown by Peter Traykovski was used to acquire these images. They were geotagged in flight by the UAS. It 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 10.64) 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 2016-055-FA " -Caption-Abstract="Town Neck Beach, Sandwich, Massachusetts, USA from survey 2016-055-FA " -Caption="Town Neck Beach, Sandwich, Massachusetts, USA from survey 2016-055-FA " -sep ", " -keywords="Town Neck Beach, Sandwich, Massachusetts, 2016-055-FA, UAS, aerial imagery, USGS " -comment="Photo from down-looking UAS camera during survey 2016-055-FA." -Credit="U.S. Geological Survey" -Contact= "WHSC_data_contact@usgs.gov" -Artist="Peter Traykovski" *.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, image name '2016054FA_U016DJP3_20160125T201139Z_DJI_0099.JPG', 2016054FA is the survey ID, U029 is the internal identifier code, DJP3 is the internal camera ID, 20160125 is the UTC date in format YYYYMMDD. A 'T' is used to separate UTC date from UTC time in format HHMMSS followed by a Z (for Zulu), and 'DJI_0099.JPG' is the original raw photo name appended to the end of the new filename.
