The objective of the fieldwork was to evaluate the quality and cost of mapping from UAS images. Low-altitude (approximately 120 meters above ground level) digital images were obtained from cameras in a fixed-wing unmanned aerial vehicle (UAV) flown from the lawn adjacent to the Coast Guard Beach parking lot on 1 March, 2016. The UAV was a Skywalker X8 flying wing operated by Raptor Maps, Inc., contractors to the U.S. Geological Survey. U.S. Geological Survey technicians deployed and mapped 28 targets that appear in some of the images for use as ground control points. All activities were conducted according to Federal Aviation Administration regulations and under a National Park Service Scientific Research and Collecting Permit, study number CACO-00285, permit number CACO-2016-SCI-003. Two consecutive UAS missions were flown, each with two cameras, autopilot computer, radios, and a global navigation satellite system (GNSS) positioning system as payload. The first flight (f1) was launched at approximately 1112 EST, and followed north-south flight lines, landing at about 1226 EST. Two Canon Powershot SX280 12-mexapixel digital cameras, designated rgb1 and rgb2 made images during this flight. The second flight (f2) was launched at 1320 EST and followed east-west flight lines, landing at 1450 Eastern Standard Time (EST). Prior to f2, rgb2 was replaced with a Canon SX280 modified with a Schott BG 3 filter to emphasize light at near-infrared wavelengths, designated nir1. Rgb1 and nir1 made images during this second flight. The four files are tables of images obtained from the two cameras during the two flights. These tables, which are text files of comma-separated values, contain the image file name, date and time (Universal Time; UT), longitude and latitude (WGS84 decimal degrees), easting and northing (NAD83(2011) UTM Zone 19 North meters, obtained by conversion of the latitude and longitude), and elevation (approximate meters above mean sea level) determined from the UAS GNSS system. Note that this location information was only used to determine proximity of images, and was replaced with calculated camera locations in photogrammetric processing. Purpose: The objective of these tables are to catalog the file names, times, and locations of the images for convenience of users.

Browse_Graphic_File_Type: JPEG Data_Quality_Information: Logical_Consistency_Report: All aerial images were acquired with one of the two 12-megapixel digital cameras (Canon Power Shot SX280 HS) mounted in the UAS. Two consecutive UAS missions were flown. The first flight (f1) was launched at approximately 1112 Eastern Standard Time (EST), and followed north-south flight lines, landing at about 1226 EST. Two 12-megapixel digital cameras (Canon Power Shot SX280 HS), designated rgb1 and rgb2 recorded images during this flight. The second flight (f2) was launched at 1320 EST and followed east-west flight lines, landing at 1450 EST. Prior to f2, rgb2 was replaced with a Canon SX280 modified with a Schott BG 3 filter to emphasize light at near-infrared wavelengths. This camera was designated nir1. Rgb1 and nir1 recorded images during this second flight. All images had a resolution of 4000 x 3000 pixels x 24 bits and were saved in JPEG format with compression level 6. The images included date, time, GPS location, and camera exposure information in the EXIF portion of the files. The dates and times are in Universal Time (UT). Images were contained in four directories, designated f1_rgb1, f1_rgb2, f2_rgb1, and f2_nir1. The directory naming convention denotes the flight number (f1 or f2) and camera number (rgb 1 or 2, or nir 1, where rgb indicates red-green-blue, and nir indicates near-infrared). Image names take the form of IMG_nnnn.JPG, where nnnn is an image number assigned by the camera. The camera automatically created a new directory and started renumbering images when the image number limit of 9999 was reached so, for a given flight, image numbers do not always start at 0001 and may not be sequential. In addition, the same image number (and image name) may occur in more than one flight. Completeness_Report: All images obtained during flights are included. Several images did not include altitude data in the EXIF information. The images with missing altitude data are: f1_rgb1\IMG_9569.JPG; f2_rgb1\IMG_1090.JPG, IMG_1320.JPG, IMG_1393.JPG, IMG_1394.JPG, IMG_1472.JPG, IMG_2183.JPG; f2_nir1\IMG_0045.JPG, IMG_0119.JPG, IMG_0195.JPG, IMG_0311.JPG, IMG_0530.JPG, IMG_0754.JPG, IMG_8840.JPG, IMG_9783.JPG, IMG_9811.JPG, IMG_9813.JPG. These images are assigned an altitude of -99.9 in the .CSV files. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positions recorded in the EXIF portion of the images were derived from a u-blox 7 GNSS module, which receives signals from GPS and GLONASS satellites, but is otherwise uncorrected. Horizontal locations are nominally accurate to approximately 3 meters, but may be off by as much as 10 meters. Data were recorded in geographic coordinates in the GPS reference frame (WGS84) and subsequently converted to NAD83(2011) UTM Zone 19 North (meters). No quality assessment or quality control has been performed for these data. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positions recorded in the EXIF portion of the images were derived from a u-blox 7 GNSS module, which receives signals from GPS and GLONASS satellites, but is otherwise uncorrected. Vertical locations are less accurate than horizontal positions and may be off by 30 meters. Altitudes are in meters above sea level. No quality assessment or quality control has been performed for these data.

Process_Step: Process_Description: Lists of the images in each of the four directories were made using a Python script (exif2track.py) that extracted date, time, latitude, longitude, and altitude from the EXIF portion of the images and used a Python version of PROJ4 software to convert the geographic coordinates (in WGS84) to NAD83(2011) coordinates in UTM Zone 19 North meters. Altitude is relative to mean sea level. The CSV file name corresponds to the image directory.
