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 locations of transect points surveyed on January 22, February 11, March 30 and September 21, 2016 that can be used to evaluate photogrammetric products from imagery collected on the same days. No transect data was collected on January 25.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Spectra Precision SP80 global navigation satellite system (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 known location that served as a benchmark, called BMOPUS, for subsequent field efforts. On return trips the base location was determined via localization with a rover positioned on BMOPUS. 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 overall accuracy of the transect point locations, based on the accuracy of the reference point and repeat measurements of targets and other known locations was 3.5 cm (horizontal) and 4.3 cm (vertical).
Logical_Consistency_Report:
There is one text file for each of the four days that transect points were collected; each lists the positions of transect points with horizontal coordinates in NAD83(2011) UTM Zone 19 North (meters), and vertical coordinates in NAVD88 GEOID 12b (meters).
Completeness_Report:
The data is complete for each field activity. Positions of the transect points collected are listed in the text files. No transect data was collected on January 25.
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 among the five measurements and the range (minimum to maximum values) 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), Easting (m) 376707.744 (0.0175), Orthometric elevation (m) 2.692(0.0398). Transect points 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 transect points locations is +/- 3.5 cm (horizontal) and +/-4.3 cm (vertical). Conversions from satellite coordinates to NAD83(2011) UTM zone 19N (EPSG::6348) and NAVD88 were made by Carlson SurvCE software in the data collector.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical positions were determined with GNSS rovers receiving real-time differential corrections from a GNSS base station localized to a temporary benchmark on a concrete pad under the trash bins at the east end of the Town Neck beach parking lot, Sandwich MA (BMOPUS). (see Horizontal_Positional_Accuracy_Report for a complete description of the survey methods).

The transect points may be used to evaluate the photogrametric products produced from aerial images taken on the same day at Town Neck Beach, Sandwich, MA.
Process_Step:
Process_Description:
All transect point 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. See Horizontal_and vertical Positional_Accuracy_Report for a complete description of the survey methods. Transect point locations were recorded as targets were deployed or retrieved, or during flight operations. Transect points were simply measurements of bare ground elevation, usually on sand, with associated horizontal coordinates. The transect locations were collected at the same time and with the same equipment as the targets. Process date is the same as collection date, which for the four events is January 22, February 11, March 30 and September 21, 2016. The process date indicated is the last of those events.
