Description:

Abstract:

Low-altitude (80-100 meters above ground level) digital images of Town Neck Beach in Sandwich, Massachusetts were obtained from a camera mounted on a small unmanned aerial system (UAS; also known as a drone). Imagery was collected at close to low tide on seven 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 and Marine Geology Program and were conducted under USGS field activity numbers 2017-005-FA, 2017-008-FA, 2017-010-FA, 2017-014-FA, 2017-027-FA, 2017-029-FA, and 2017-050-FA.

Purpose:

This dataset consists of locations of targets deployed and surveyed on January 9, January 25, February 14, March 16, April 28, May 4, and September 18, 2017, and in-place features surveyed on January 25, February 24, and 16 March, 2017 that can be used as ground control points (GCPs) to constrain photogrammetric processing of imagery collected on the same days.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Spectra Precision SP80 GNSS receivers were used to locate the targets used as ground control points and transect coordinates. One was configured as a base station and established at a fixed, known location, and broadcast differential corrections to rovers in real time. On various days, one or two SP80 receivers and/or a Spectra Precision model ProMark 800 GNSS receiver functioned as rovers that received corrections from the base and were used to locate targets that served as ground control points and measure transect points. The base location was determined via localization with a rover positioned on a local reference point designated BMOPUS. The overall horizontal accuracy of the target locations, based on the accuracy of the reference point and repeat measurements of targets and other known locations was 1.5 cm and the vertical accuracy was 0.5 cm.

Logical_Consistency_Report:

There is one text file for targets per survey day and one additional file for in-place features. Each target file lists the positions of each temporary target with horizontal coordinates in NAD83(2011) UTM Zone 19 North (meters), and vertical coordinates in NAVD88 GEOID 12b (meters). Two types of targets were always used, and are distinguished by labels in the first column of the data file: Txx indicates the PVC targets and Pxx indicates the plywood targets (where xx is the target number). On two days (January 9 and January 25) round targets with binary codes readable by Agisoft Photoscan software were used; these are denoted as "target xx", where xx corresponds the encoded number. 'PM' may be appended to a label, if so it indicates a second occupation later in the afternoon. On one day (May 4) a circular orange target with a large H was used as a drone landing site and a ground control point, and is labeled as H in the file. The in-place features file lists the surveyed locations of pre-existing features visible from the air. In-place features were surveyed using the same equipment and methods and recorded in the same coordinate system. In-place features were surveyed on January 25, February 24, and March 16. One or more photos of each in-place feature were taken to allow users to match the features with their coordinates. The feature labels are descriptive: 65_FRMN_GRATE refers to a drainage grate near 65 Freeman Avenue (three photos); BBR1 (two photos), BBR5 (one photo), and BBR9 (one photo) refer to features on Bay Beach Road; E_BWALK_FAT (two photos) refers to a wide section in the marsh boarwalk; E_BWALK_T (one photo) refers to the junction in the marsh boardwalk; FMN_GRATE_N (three photos) refers to a drainage grate on the north side of the junction of Freeman Avenue and Wood Avenue; JR4 (six photos) refers to a rock on a beach groin surveyed by Jonathan Borden; and WHITECAP_PATH (three photos) refers to a feature on Whitecap Path. In two cases (BBR1 and E_BWALK_T) the feature was surveyed on two occasions; these labels include _1 and _2 to distinguish them. Photos of in-place features are named according to the feature labels and the date of the photograph. If multiple photos of the same feature are included, numbers are included. For example, E_BWALK_FAT_1_25Jan2017.jpg is one of two photos of E_BWALK_FAT taken on January 25, 2017.

Completeness_Report:

On January 9 (2017-005-FA), the survey was extended slightly east and south to encompass the adjacent Spring Hill Beach; the other days only cover Town Neck Beach. The data is complete for each field activity. Positions of all of the temporary targets that serve as ground control points deployed each day are listed in the text files. As suggested by the non-sequential numbering of some of the in-place feature labels, not all of the in-place features that were survyed are included. However, all of the in-place features that had identifying photos and were deemed useful for constraining the photogrammetric reconstruction are included.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal positions were determined with GNSS rovers receiving real-time differential corrections from a GNSS base station established over a benchmark on the corner of a concrete pad under the trash bins at the east end of the Town Neck Beach parking lot, Sandwich, MA. The base station was a Spectra model SP80 GNSS receiver with UHF radio and external antenna mounted on a separate tripod. The antenna height was 2.25 m. The coordinates of the reference point (designated BMOPUS) were determined from precise orbit On-line Positioning User Service (OPUS) solutions using GPS data collected during five 2- to 7-hour occupations between November 2015 and December 2016. The final values are the averages of the five positions, and the uncertainty is the quadrature sum of the range (minimum to maximum values) among the five measurements and the range for individual measurements, as reported by OPUS. The coordinates (uncertainty) in NAD83(2011) (Epoch:2010.0000) UTM Zone 19, elevation NAVD88 (geoid 12B) for the reference point BMOPUS are: Northing (m) 4624914.408 (0.0067) meters, Easting 376707.744 (0.0175) meters, Orthometric elevation 2.692(0.0398) meters. The coordinates of the targets and in-place features were measured with rovers with an estimated precision of +/- 3 cm (horizontal) and +/-1.6 cm (vertical). Combined with the uncertainty of the reference point, the overall estimated accuracy of target locations used for GCPs is +/- 3.5 cm (horizontal) and +/-4.3 cm (vertical).

Process_Step:

Process_Description:

All targets and transect locations were measured with an RTK-GNSS system by the USGS field crew at Town Neck Beach, Sandwich, MA during daylight around the time of low tide. Two kinds of targets were used: commercial targets (4 ft x 4 ft x 4-mil thick PVC plastic sheets with black and white diamond patterns and grommets in corners (Berntsen International, Inc. product number AT48IC-STK), and plywood targets (2 ft x 2 ft x 1/2-inch thick plywood boards painted with black and white squares). The commercial targets were designated "Txx" and the plywood targets were designated "Pxx", where xx is the target number. 'PM' may be appended to a label, if so it indicates a second occupation later in the afternoon. In-place features are associated with photos to help identify them in aerial imagery. See Data_Quality_Information for a complete description. See Horizontal and vertical Positional_Accuracy_Report for a complete description of the survey methods. Data from the survey instruments was produced in horizontal coordinate reference system (CRS) NAD83(2011) UTM Zone 19 N (meter), and the vertical CRS NAVD88. These were reformatted (e.g., column locations were changed) when were loaded into Photoscan during photogrammetry processing. They were subsequently exported from Photoscan as comma-separated text (.txt) files with a two-line header. We hand-edited those files to replace the two-line header supplied by Photoscan with the following header: "#Label,X/Easting (m NAD83(2011) Zone 19N),Y/Northing (m NAD83(2011) Zone 19N),Z/Elevation (m NAVD88)". Process date is the same as collection date, which for the 8 events is January 9, January 25, February 14, February 24, March 16, April 28, May 4 and September 18. The process date indicated is the last of those events.

Overview_Description:

Entity_and_Attribute_Overview:

Eight text files and 22 digital images (.jpg files) are in the .zip. Seven files contains the locations and elevations of the GCPs on a specific date. Each file contains one header line, followed by lines with 4 columns of comma-separated values. The header line describes the column contents as follows: #Label, X/Easting (m NAD83(2011) Zone 19N), Y/Northing (m NAD83(2011) Zone 19N), Z/Elevation (m NAVD88). Subsequent lines contain the labels and coordinates for each GCP deployed on that day. The labels identify which type of target was used, where Txx indicates the 4-ft square PVC plastic targets, and Pxx indicates the 2-ft square plywood targets (xx is the target number in both), and H indicates the orange disk used as the UAS landing spot. Each file has a different number of data records: 2017-01-09_SandwichTNB_GCPs.txt has 39, 2017-01-25_SandwichTNB_GCPs.txt has 41, 2017-02-14_SandwichTNB_GCPs.txt has 26, 2017-03-16_SandwichTNB_GCPs.txt has 26, 2017-04-28_SandwichTNB_GCPs.txt has 26, 2017-05-04_SandwichTNB_GCPs.txt has 27, 2017-09-18_SandwichTNB_GCPs.txt has 26. The eighth .txt file contains the same information for the in-place features surveyed on various dates. This file (2017_All_SandwichTNB_in_place_GCPs.txt) has the same format and contains 11 records after the header. The 22 digital image files are in JPEG format. The image file names of photos of in-place features are named according to the feature labels and the date of the photograph. If multiple photos of the same feature are included, numbers are included in the filenames. For example, E_BWALK_FAT_1_25Jan2017.jpg is one of two photos of E_BWALK_FAT taken on January 25, 2017.
