The data contains topographic survey data collected during the installation of the camera. Data were collected on foot by a person equipped with a GNSS antenna affixed to a backpack outfitted for surveying location and elevation data (XYZ). The GNSS measurements were made using Post-Processed Kinematic (PPK) corrections from a GNSS base station occupying a temporary benchmark (MK02) located approximately 1 kilometer (km) from the study area. Purpose: The purpose of this dataset is to provide geospatial and topographic data, in support of a coastal video monitoring station at Waiakāne, Moloka'i, Hawai'i. Following U.S. Geological Survey (USGS) data management protocols, this survey was assigned a USGS field activity number (FAN), 2018-617-FA. Additional information about the field activity from which these data were derived is available on the Coastal and Marine Geoscience Data System (CMGDS): https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-617-FA.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These survey data were measured using survey-grade dual-frequency GNSS receivers operating in Post-Processed Kinematic (PPK) mode using corrections referenced to a GNSS base station occupying a temporary benchmark (MK02) located approximately 1 kilometer (km) from the study area. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). The standard deviation of the four OPUS-derived horizontal positions was 0.004 meters. The mean reported horizontal precision of the PPK measurements was 0.015 meters (standard deviation of 0.002). The magnitude of additional errors resulting from uncertainty in the base station reference position, antenna height measurement errors, and errors resulting from varying posture and sinking in sand during backpack surveying are unknown. Horizontal coordinates are referenced to the North American Datum of 1983 (National Spatial Reference System PA11) Universal Transverse Mercator Zone 4 North (NAD83(PA11)/UTM Zone 4N) coordinate system, with a resolution of 0.001 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: These survey data were measured using survey-grade dual-frequency GNSS receivers operating in Post-Processed Kinematic (PPK) mode using corrections referenced to a GNSS base station occupying a temporary benchmark (MK02) located approximately 1 kilometer (km) from the study area. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). The standard deviation of the four OPUS-derived vertical positions was 0.008 meters. The mean reported vertical precision of the PPK measurements was 0.022 meters (standard deviation of 0.002). The magnitude of additional errors resulting from uncertainty in the base station reference position, antenna height measurement errors, and errors resulting from varying posture and sinking in sand during backpack surveying are unknown. Vertical positions are orthometric heights relative to local mean sea level, derived using GEOID12B, coordinate system, with a resolution of 0.001 meters. Lineage: Process_Step: Process_Description: ACQUISITION The GNSS ground survey was conducted using a Trimble R7 survey-grade dual-frequency GNSS receiver set to record raw GNSS observables in Post-Processed Kinematic (PPK) mode. Topographic measurements of the ground surface were made using the GNSS receiver mounted on a GNSS-survey backpack and set to collect continuous observations at a rate of 1 hertz (Hz) while the surveyor walked on the ground surface. These data acquisition steps are similar to those reported in Brown and others (2018), the difference being the GNSS recording interval and the GNSS survey equipment model.

The base receiver was programmed to record raw GNSS observations during survey operations. Reference coordinates for MK02 were established using the mean position derived from four static GNSS occupations with durations greater than 4 hours each submitted to the National Geodetic Survey Online Positioning User Service (NGS OPUS). These data were then used to post-process the GNSS measurements using the Trimble Business Center ver. 4.30 software package. The differentially-corrected, precise GNSS antenna positions were exported in American Standard Code for Information Interchange (ASCII) text format, with projected horizontal coordinates in NAD 83, UTM Zone 4N, and orthometric elevation in GEOID12B. These post-processing steps are similar to those reported in Brown and others (2018). Ground elevations were determined by subtracting the GNSS antenna height above the ground. Following OCM Partners (2024), the orthometric elevation was converted from GEOID12B to a local mean sea level by subtracting 0.601 meters. The GEOID12B to local mean sea level vertical adjustment for Moloka'i was derived by OCM Partners (2024) from published National Geodetic Survey control point datasheets. The final beach profile data were written to a text file (.xyz) in tabular format, with columns representing: 1) Easting (NAD83, UTM Zone 4N), 2) Northing (NAD83, UTM Zone 4N), and 3) Orthometric Elevation (local mean sea level, GEOID12B).
