Description:

Abstract:

This dataset contains the locations of independent survey points acquired on the same day that images were obtained from unmanned aerial systems (UAS) flown in the Cape Cod National Seashore. The overall objective of the field work 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. 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. This dataset contains locations of both in place and placed targets that may be used as ground control to constrain photogrammetric reconstructions. One hundred and forty-four (144) points were measured along several cross-shore transects on the beach. These points were measured with real-time differential global positioning system (GPS) and have horizontal and vertical uncertainties of approximately +/ 0.03 m. These points were not used in photogrammetric processing, so they can be used for independent evaluation of photogrammetric products. The independent survey points are listed in file CACO_transect_Points_20160301.csv.

Purpose:

The objective of obtaining these transect survey points was to provide independent topographic measurements for evaluation of photogrammetric products.

Data_Quality_Information:

Logical_Consistency_Report:

The text file CACO_transect_points_20160301.csv contains the locations (coordinates in UTM Zone 19 meters and latitude and longitude) of transect points. All points were mapped using a differential GPS rover instrument operated by Barry Irwin. Points are labelled TSn, where n refers to cross-shore transect number, ranging from 1 to 9. Point numbers begin at 108 and ascend to 252, but gaps in the numbers occur when other features such as ground control points were mapped.

Completeness_Report:

Locations of all of the transect points are listed in the .csv file. No ground photos of these points are available.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal positions were determined with a GNSS rover receiving real-time differential corrections from a GNSS base station established over a temporary benchmark on the lawn of the NEED building at Coast Guard Beach. 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 (named CGB_OPUS) were determined from an ultra-rapid precise orbit On-line Positioning User Service (OPUS) solution based on GPS data from a five-hour occupation on January 11, 2016. Coordinates in NAD83 2010(2011) UTM Zone 19, elevation NAVD88 (geoid 12a) for the reference point are: Northing (m) 4632792.698 (+/-0.002), Easting (m) 421296.521 (+/-0.003), Orthometric elevation (m) 12.880 (+/-0.012). The uncertainties in parentheses represent peak-to-peak values. The rover was a Spectra Precision model ProMark 800 GNSS receiver 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). This instrument was operated by Barry Irwin. The rover antenna was mounted on 2-m survey rods with bubble level and 5-cm (2-inch) sand foot. The instruments were used to stake three reference points established near the base station at the beginning and end of the day. The average absolute deviation largest horizontal or vertical difference measured was +0.03 m. Conversions from satellite coordinates to NAD83(2011) UTM Zone 19 and NAVD88 were made by Carlson SurvCE software in the data collector.

Vertical positions were determined with one of two GNSS rovers receiving real-time differential corrections from a GNSS base station established over a temporary benchmark on the lawn of the NEED building at Coast Guard Beach (see Horizontal_Positional_Accuracy_Report for a complete description of the survey methods). The instruments were used to stake three reference points established near the base station at the beginning and end of the day. The average absolute deviation largest horizontal or vertical difference measured was +0.03 m.

Lineage:

Process_Step:

Process_Description:

One hundred and forty-four (144) transect point locations were measured along nine cross-beach transects by a technician on foot. The transects were determined by eye, and the spacing of the points by pace, and the precisely measured points provide roughly east-west trending profiles of cross-shore topography from the waters edge (near low tide) to the dune crest. Horizontal and vertical positions were determined with a GNSS rover receiving real-time differential corrections from a base station. For details, see Horizontal and Vertical Positional Accuracy sections. Transect point measurements were converted to NAD83 2010(2011) and NAVD88 (Geoid 12a) as the data were collected. The measurements were exported from the data collector as UTM Zone 19 (meters), NAVD88 (meters), and latitude and longitude (decimal degrees), along with date and time, in a text file (CACO_transect_points_20160301.csv).
