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 image locations are provided for use with the referenced images in creating an elevation model for Black Beach, Falmouth, Massachusetts.

Data_Quality_Information:
Logical_Consistency_Report:
Camera position at the time of image capture were acquired through GPS and GLONASS positioning. Geographic coordinates are referenced to WGS 84 and altitudes are in feet above mean sea level. Consistency checks were performed by comparing the images with the camera positions projected over a map of the study area. All information was found to agree. 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.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal camera position at the time of image capture was acquired through GPS and GLONASS positioning. Horizontal locations are nominally accurate to approximately 3 feet, but may be off by as much as 10 feet.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical camera position at the time of image capture was acquired through GPS and GLONASS positioning. Vertical locations are less accurate than horizontal positions, nominally accurate to about 5 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 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:
A Python version 2.7 script was run to extract GPS data from the image headers and format the output CSV table. The script used ExifTool (version 10.43) with the following command was used to create the CSV: exiftool -csv -filename -DateTimeOriginal -GPSLongitude -GPSLatitude -GPSAltitude -n imagedirectory > bb20160318_UAS_imagelocations.csv The path to the image directory was substituted for 'imagedirectory' in the command. The -csv flag writes the information out in a comma-delimited format. The -n option formats the latitude and longitude as signed decimal degrees. The DateTimeOriginal tag was used because the GPS time was not recorded in the EXIF data by the UAS.
The table output by ExifTool was reformatted and the fields Easting and Northing were added. This involved converting the datetime from Eastern Daylight time to UTC (added 4 hours) and then splitting the values into dates and times. Then, fields SourceFile and DateTimeOriginal were removed. Fields GPSLongitude, GPSLatitude, and GPSAltitude were stripped of the 'GPS' prefix and ‘_ft’ was added to the Altitude column label. The longitude and latitude coordinate pairs referenced to WGS84 were converted to easting and northing in UTM Zone 19 North with a datum transformation to NAD83 using the function 'transform' in the Python module 'pyproj' and the values were stored in new columns 'Easting' and 'Northing'. The transformation was performed in Python with the following call, in which lon and lat stand in for the value of longitude and latitude in one row and east and north are the resulting easting and northing in NAD83 UTM Zone 19N:
import pyproj east, north = pyproj.transform(p1=pyproj.Proj(init='epsg:4326'), p2=pyproj.Proj(init='epsg:26919'), x=lon, y=lat)
