Description:
Abstract:
Imagery acquired with unmanned aerial systems (UAS) and coupled with structure from motion (SfM) photogrammetry can produce high-resolution topographic and visual reflectance datasets that rival or exceed lidar and orthoimagery. These new techniques are particularly useful for data collection of coastal systems, which requires high temporal and spatial resolution datasets. The U.S. Geological Survey worked in collaboration with members of the Marine Biological Laboratory and Woods Hole Analytics at Black Beach, in Falmouth, Massachusetts to explore scientific research demands on UAS technology for topographic and habitat mapping applications. This project explored the application of consumer-grade UAS platforms as a cost-effective alternative to lidar and aerial/satellite imagery to support coastal studies requiring high-resolution elevation or remote sensing data. A small UAS was used to capture low-altitude photographs and GPS devices were used to survey reference points. These data were processed in an SfM workflow to create an elevation point cloud, an orthomosaic image, and a digital elevation model.
Purpose:
These images were collected for use with photogrammetric techniques to derive topographic and visual reflectance products.

Data_Quality_Information:
Logical_Consistency_Report:
Consistency checks were performed by comparing the images with the information recorded in the EXIF header and by displaying camera positions over a map of the study area. The images and map aligned in a consistent manner. Geographic coordinates are referenced to WGS84 and altitudes are in feet above mean sea level. Image filenames take the form of nnnnnnnFA__fnncnn_yyyymmddThhmmssZ_DJI_nnnn.JPG, where nnnnnnnFA is the Woods Hole Coastal and Marine Science Center’s field activity number; fnncnn is the flight number and camera number specific to the survey; yyyymmddThhmmssZ is the date and time (UTC) in format year, month, day, T, hours, minutes, seconds; and DJI_nnnn is the original filename.
Completeness_Report:
The dataset contains 250 images collected by the DJI Phantom. The first four images were removed because they were taken before the DJI had arrived at the survey starting point. The ground area captured is approximately 17.5 hectares over the outlet of Great Sippewissett Marsh. The UAS flew 15 transects spaced 30 m apart across the width of the survey site (east-west oriented) at an altitude of 35 m with photos automatically taken every 20 meters (~17 photos per transect). This design ensured an overlap of 80 percent between photos and an image resolution of 2.5 cm.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Camera position at the time of image capture were acquired through GPS and GLONASS positioning. Horizontal locations are nominally accurate within approximately 3 meters. Navigation is stored in the EXIF header of the image in geographic coordinates in the GPS reference frame (WGS84).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Camera position at the time of image capture was acquired through GPS and GLONASS positioning. Vertical locations are stored in the EXIF header of the image. These values are less accurate than horizontal positions and are nominally accurate within approximately 10 feet.

Process_Description:
A DJI Phantom 3 Professional quadcopter with onboard camera, which uses a Sony EXMOR 1/2.3" sensor, was operated through a tablet computer for flight programming and control. The flight was conducted by Simon Miner of Woods Hole Analytics using Maps Made Easy (MME; https://www.mapsmadeeasy.com; Automotive Data Research) for route design and automated flight programming, including camera shutter control and vehicle return for battery replacement. Photographs were collected in JPEG format by the built-in camera on the DJI and capture information was stored in the accompanying Exchangeable Image File (EXIF). The camera model is FC300X with a lens F-number of f/2.8. All images had dimensions of 4000 x 3000 pixels x 24 bits and were saved in JPEG format. The approximate camera position at the time of each photograph was measured by a GPS receiver onboard the UAS and recorded in the image EXIF data. All activities were conducted according to Federal Aviation Administration regulations. Images were collected between approximately 1101 EDT at the most southwestern point and 1129 EDT at the most northeastern point. The survey was timed to correspond to the time of local low tide. Weather conditions included sunny skies, with winds of about 10.3 m/s. The DJI captured an image approximately every 20 meters in 15 east-west transects spaced 30 m apart at an altitude of 35 m (115 feet). This design ensured an image resolution of 2.5 cm and an overlap of 80 percent between photos. The images were downloaded from the camera on the day of flight.

Process_Description:
ExifTool (version 10.43) was run to write standard distribution information to the headers of each full-resolution JPEG image. The following tags were populated in the JPEG image headers. Information is duplicated in some tags. Multiple, overlapping tags are employed to make the images work in a variety of software packages. Every image in this collection was populated with the same content for the following tags. The tag name and content is listed with the tag type below:
JPEG tags:

Also using ExifTool, the original filename (e.g. DJI_0001.jpg) was written to the EXIF tag OriginalFileName. Once the original filename was saved, the image files were renamed to the format of nnnnnnnFA__fnncnn_yyyymmddThhmmssZ_DJI_nnnn.JPG, where nnnnnnnFA is the Woods Hole Coastal and Marine Science Center’s field activity number; fnncnn is the flight number and camera number specific to the survey; yyyymmddThhmmssZ is the date and time (UTC) in format year, month, day, T, hours, minutes, seconds; and DJI_nnnn is the original filename.
To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 9.4.6.0): exiftool.exe -csv -f -filename -DateTimeOriginal -GPSLongitude -GPSLatitude -n -Artist -Credit -comment –Contact -keywords -Caption -Copyright -CopyrightNotice -Caption-Abstract -ImageDescription *.jpg > out.csv The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees.

Entity_and_Attribute_Overview:
Photograph capture information is stored in Exchangeable Image File Format version 2.3 (EXIF). The EXIF data logged by the UAS camera record parameters specific to each photo, including date, time, camera exposure, latitude, longitude, altitude, and pitch, roll, and yaw values. The dates and times were recorded in the tags DateTime, DateTimeDigitized, and DateTimeOriginal in Eastern Daylight Time (EDT). GPS data were logged in WGS 1984 in the tags with the GPS prefix (e.g. GPSLatitude). UAS rotation was recorded in the XMP tags FlightPitchDegree, FlightRollDegree, and FlightYawDegree. All images had dimensions of 4000 x 3000 pixels x 24 bits and were saved as JPEG format.
To extract the information from the image headers using ExifTool, the following command can be used (tested with ExifTool version 9.4.6.0): exiftool.exe -csv -f -filename -DateTimeOriginal -GPSLatitude -GPSLongitude -n -GPSAltitude -FlightPitchDegree -FlightRollDegree -FlightYawDegree *.jpg > out.csv The -csv flag writes the information out in a comma-delimited format.
