This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Madeira Beach, Florida. Data were collected on foot by a person equipped with a Global Positioning System (GPS) antenna affixed to a backpack outfitted for surveying location and elevation data (XYZ) along pre-determined transects. The horizontal position data are given in the Universal Transverse Mercator (UTM) projected coordinate system, Zone 17 North (17N), referenced to the North American Datum of 1983 (NAD 83); the elevation data are referenced to the North American Vertical Datum of 1988 (NAVD 88), GEOID12B.
The purpose of this dataset is to provide geospatial and topographic profile data, in support of a coastal video monitoring station at Madeira Beach, Florida. To ensure that SPCMSC data management protocols were followed, this survey was assigned a USGS field activity number (FAN), 2017-353-FA. Additional survey and data details are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-353-FA.

Cross-shore profiles were quality checked for accuracy by comparing elevations where cross-shore and alongshore transects overlapped.
Cross-shore profiles were quality checked for consistency by comparing elevations to previous or subsequent surveys of the same transects.
Initial survey planning included the acquisition of 30 transects (26 cross-shore, 4 alongshore). However, no alongshore transects were collected and only 25 cross-shore transects were collected during this survey; lines 1 to 4 and 60 were not collected during this survey due to time limitations. This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.
The horizontal accuracy of the post-processed kinematic GPS data is +/- 1 centimeters (cm), according to the manufacturer's specifications.
The vertical accuracy of the post-processed kinematic GPS data is +/- 2 centimeters (cm), according to the manufacturer's specifications.
PLANNING
Transects were created using the MathWorks MATLAB R2016a computing environment. Cross-shore transects were planned perpendicular to the beach by utilizing a measured 2010 lidar shoreline to find an average shoreline angle, and were cast at locations of groins (cross-shore perpendicular structures that are connected to land and extend into the ocean) and at 3 equally spaced alongshore locations between groins in the area of interest by utilizing Google Earth to determine the location of the groins. This resulted in 25 transects spaced approximately 23 meters (m) apart and spanning approximately 555 m in the alongshore direction. An additional cross-shore transect was planned in the middle of the study area in support of the USGS National Assessment of Coastal Change Hazards project. Four alongshore transects, spanning the length of the study area, were cast approximately 10 m apart in the cross-shore, spanning from the dune toe to the shoreline.

AQUISITION
Transect lines were surveyed, on foot, by a person equipped with a Global Positioning System (GPS) receiver and a GPS antenna affixed to a SECO© surveying backpack, and connected to a Windows laptop PC running Hypack 2016 survey acquisition software. Kinematic GPS data were recorded at 5 Hz with an Ashtech ProFlex™ 500/800 Global Navigation Satellite System (GNSS) receiver and an Ashtech® GNSS geodetic survey antenna. The time associated with the beginning and end of surveying each transect line was recorded on the laptop in HYPACK by the surveyor.

GPS POST-PROCESSING
Raw GPS kinematic data recorded on the surveying receiver were post-processed using GNSS post-processing software GrafNav (Waypoint Product Group) version 8.7 in order to achieve higher horizontal position and elevation data accuracies. The kinematic GPS data recorded by the surveying receiver were processed in NAD 83 geographic coordinates to concurrent static GPS data recorded by a local base station of known position (NAD 83). The base station used was the Florida Permanent Reference Network (FPRN) site at Indian Shores (FLIS). The final, differentially-corrected, precise GPS positions were exported in American Standard Code for Information Interchange (ASCII) text format, with projected horizontal coordinates in NAD 83, UTM Zone 17N, and vertical coordinates in NAVD 88, GEOID12B.

DATA PROCESSING
Beach profile horizontal position and elevation data for each individual transect were extracted from the post-processed GPS data based on the surveying times recorded with HYPACK using the MathWorks MATLAB R2016a computing environment. The data were smoothed in the cross-shore direction to reduce the noisiness of the highly-sampled elevation data, using a moving 1-meter wide Hanning filter in MATLAB. The data were quality-controlled in MATLAB to remove invalid data points by: eliminating points with poor GPS data quality, visually inspecting plots of horizontal positions and discarding points not on the cross-shore beach profile lines (e.g., points just prior to and just after a transect), and visually inspecting plots of elevation and discarding points with erroneous GPS data (e.g., spikes in the GPS data). Lastly, the elevation data were adjusted by subtracting the elevation of the GPS antenna above the ground, when attached to the surveying backpack, during the survey (1.98 m). The final beach profile data were written to individual text files (.xyz) in tabular format, with columns representing: 1) Easting (NAD83, UTM Zone 17N), 2) Northing (NAD83, UTM Zone 17N), and 3) Orthometric Elevation (NAVD 88, GEOID12B).
