Description:
Abstract:
Low-altitude (80 and 100 meters above ground level) digital images were collected by the USGS Woods Hole Coastal and Marine Science Center (WHCMSC) Aerial Imaging and Mapping Group (AIMG) over an area of the Plum Island Estuary and Parker River National Wildlife Refuge (NWR) in Massachusetts on November 14, 2017 and March 28, 2019 to document marsh stability over time and quantify sediment movement. A 3DR Solo uncrewed aircraft systems (UAS) was equipped with either a Ricoh GR II digital camera for true-color color photos, used to produce digital elevation models and ortho images, or a MicaSense RedEdge multispectral camera that captures five specific bands of the visible spectrum (blue, green, red, red edge, and near-infrared), used to classify vegetation. The MicaSense camera covered a smaller subsection of the same polygonal area of the marsh that the Ricoh imaged. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision Real-Time Kinematic Global Positioning System. This data release includes the original images from both cameras, as well as a CSV file containing the latitude and longitude coordinates, in Universal Transverse Mercator Zone 19N referenced to the North American Datum of 1983, of the ground control points needed to complete any photogrammetry projects using the original photographs, and GPS transect points used to evaluate the photogrammetry products created.
Purpose:
The objective of obtaining these ground control points was to constrain the photogrammetric products constructed from the aerial images taken, by providing survey-quality ground validation, which far exceeds the accuracy that can be provided from the photo geolocations alone. Ground control points are used to geolocate the products as accurately as possible.
Supplemental_Information:
These data were collected by the USGS Coastal and Marine Hazards and Resources Program under USGS field activity numbers 2017-057-FA and 2019-009-FA.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Spectra Precision SP80 GNSS receivers were used to collect the ground control points and transect coordinates.
Logical_Consistency_Report:
The CSV files list the locations for all ground control and transect points. The columns contain, in order, ORIGINAL_ID, Northing (UTM), Easting (UTM), Elevation (in meters), DATE_collected, and Description (whether the ground control is a target or a transect). The target names (ORIGINAL_ID) are uniquely named (e.g. P01, T20, T31); each transect (consisting of several GPS fixes along a survey line) has a unique location, however the points for that transect are all named similarly (e.g. Road). Targets included commercial targets (4 ft x 4 ft x 4 mm PVC plastic sheets with black and white checkered pattern at diagonals and grommets in corners; Berntsen International, Inc. product number AT48IC-STK), plywood targets (2 ft x 2 ft x 1/2-in plywood boards painted with black and white square checkered pattern), and black and white checkered AeroPoints (1.8 ft x 1.8 ft x 1 + 1/4-inch); manufactured by PropellerAero (only used in 2019 survey). The commercial targets were designated Tnn, the plywood targets were designated Pnn, and the AeroPoint targets were designated Ann, where nn is the one- or two- digit target number. GPS rover instruments were used by field crews to map targets for ground control points. AeroPoint targets A03, A04, and A05 were surveyed by the rover GPS due to unsuccessful upload of their internal survey measurements. Additionally, target A04 was mistakenly moved mid-survey sometime between 16:50:51 UTC and 17:01:26 UTC so only photos collected prior to it being moved were used to mark the target during photogrammetry processing. This target does not appear in the correct location in photos taken during flight 11 of field activity 2019-009-FA.

Locations for all ground control points and transect points collected are listed in the CSV text files.
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 temporary benchmark. The base station was a Spectra model SP80 GNSS receiver with UHF radio and external antenna mounted on a tripod. The antenna height was 2.25 m. The coordinates of the reference point were determined from an ultra-rapid precise orbit On-line Positioning User Service (OPUS) solution. Spectra Precision model SP80 GNSS receivers were also used as rovers, which linked via Bluetooth to a data collector (Carlson CHC LT30 Handheld Terminal running Carlson SurvCE v. 4.06 software under Windows Mobile v. 6.1 Professional operating system). Rover antennas were mounted on 2-m survey rods with bubble levels and 5-cm (2-inch) sand feet. Conversions from satellite coordinates to NAD83(2011) UTM zone 19N (EPSG::6348) and NAVD88 (Geoid 12b) were made by Carlson SurvCE software in the data collector. Horizontal accuracy based on the reoccupation of a stake locations was 1.5 cm. The uncertainty of OPUS fixes for the RTK-GPS base stations adds another 0.26 cm of uncertainty, therefore, the theoretical horizontal accuracy of the GCP and transect points is + or - 1.76 cm. Horizontal positions for the AeroPoint targets are determined from the embedded GPS. Conversions from satellite coordinates to NAD83(2011) UTM zone 19N (EPSG::6348) and NAVD88 were made using the Propeller Aero Network Correction. The theoretical horizontal accuracy is 3.00 cm.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical positions were determined with the GNSS rovers receiving real-time differential corrections from a GNSS base station established over a temporary benchmark. The theoretical vertical accuracy of the RTK GPS is 2.5 cm. For a similar survey in 2018 with the same survey equipment, an accuracy assessment determined an uncertainty of 0.54 cm. Vertical positions for the AeroPoint targets are determined from the embedded GPS. The theoretical vertical accuracy is 3.00 cm.

Process_Step:
Process_Description:
Ground control points and transect points, are listed in the CSV files 2017057FA_PlumIsland_GCP.csv and 2019009FA_PlumIsland_GCP.csv Finalized versions were created 2/6/2019 and 5/4/2022, respectively. Targets and transect measurements collected with the rover GPS were exported from the data collectors as text file in the RW5 format and then processed (referenced to the base OPUS rapid static solution) and exported to comma-separated values (CSV) files using the Carlson Report Generator for a SurvCE RW5 Report (https://www.carlsonemea.com/cwa/report ), while measurements collected by the AeroPoints were exported to comma-separated values (CSV) files from the Propeller website (www.propelleraero.com). Rover and AeroPoint datasets were combined and manually edited to filter by transect point or ground control point and extraneous columns were removed. The target data are used as an input to the Agisoft Photoscan or Pix4D software to control the data horizontally and vertically. The transect points collected within the study area are used to ground truth data products (Point Cloud, DEM and Orthomosaic) created in Agisoft Photoscan, and Pix4D.
