The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) and the U.S. Army Corps of Engineers Field Research Facility (USACE-FRF) of Duck, NC collaborated to gather alongshore ground-based lidar beach topography at Fire Island, NY. This high-resolution elevation dataset was collected on April 1, 2014, and is part of the USGS's ongoing beach monitoring effort under Hurricane Sandy Supplemental Project GS2-2B. This USGS Data Release includes the resulting processed elevation point data (xyz) and an interpolated digital elevation model (DEM).
To collect, process, and disseminate beach topography along 30 kilometers (km) of Fire Island, NY beach, stretching from Robert Moses State Park to the Wilderness Breach. The USACE-FRF team acquired and performed initial processing of the high-resolution lidar data, which is only one component of a larger dataset collected using the CLARIS platform. To ensure that SPCMSC data management protocols were followed, this survey was retroactively assigned a USGS field activity number (FAN), 14CNT02. Additional survey and data details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=14CNT02.

Areas of data overlap were initially compared against each other to measure repeatability. Depending on distance from the base station (Ashtech Z-Xtreme GPS receiver at temporary benchmark at U.S. Coast Guard: Fire Island Inlet Station) the accuracy of the scans varied from 5 to 15 centimeters (cm). The fixed structures (i.e. houses, rooflines, decks) were used to measure repeatability and the base station benchmark was used to measure accuracy. Previous airborne lidar from a 2011-2012 National Ocean and Atmospheric Administration (NOAA)/New York State Department of Environmental Conservation (NYSDEC) survey was also used as an alternative fixed structure comparison.
Repeatability: 5-15 cm
Accuracy: 5-10 cm
Lidar beach morphology data were collected by the U.S. Army Corps of Engineers' (USACE) Coastal Lidar and Radar Imaging System (CLARIS) vehicle on April 1, 2014. This survey utilized the same equipment set up and follows the same procedure as an identical survey which occurred on April 10, 2013 (2015 USGS Data Series 921). The survey vehicle traveled approximately 5 kilometers per hour (km/h) along two 30 km shore parallel transits; the first transit surveyed the seaward side of the dune and upper beach while the second transit surveyed the area near the shoreline and lower beach. The survey was designed to provide a significant overlap area of data coverage, which is used to verify system accuracy and assess survey precision.
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.

USACE-FRF Processing - Data for the survey extents was collected along with a boresight to resolve subtle differences between the scanner and the Inertial Measurement Unit (IMU). After collection, the data was post-processed using multiple software packages to produce the final digital elevation model product.

Terrestrial GPS data was post-processed with National Geodetic Survey's Continuously Operating Reference Stations (CORS) and integrated with post-processed IMU data through Applanix's POSPac GNSS software to derive a smoothed, best estimate of trajectory (SBET). After processing, quantitative quality-metrics were analyzed to ensure the trajectory accuracy met the manufacturer's specified values.

The SBET is imported into Riegl's RiProcess lidar software project where the lidar point cloud is rectified and geo-registered to a particular coordinate system, projection, and geoid model as well as applying boresight values for roll, pitch and yaw. Control monuments and previously validated datasets were used for comparison to determine the accuracy of the survey. These were measured by cutting cross-sections of the current survey overlayed on previously validated data within the software through stable structures such as houses, monuments, and road centerlines.

The processed point cloud was manipulated within RiProcess to delineate the shoreline, filter structures and vegetation, and classify points as water, vegetation, structures, and ground. The classified point cloud was exported as a .las (1.1) file.

The .las file was imported into Applied Imagery's QTModeler software where a mean-z (elevation) algorithm was applied to the point cloud data to grid the data at 0.5-meter resolution. Anti-aliasing was also applied to increase the precision of the triangulation by subdividing each grid cell into 16 equal segments and recording which segment contained the point that was used to represent the elevation value of the grid cell. When triangulation occurs, this increased level of precision will enhance the accuracy of the triangles and the subsequent sampling that occurs. The sub-grid was not retained after the model was created. During the model triangulation, any grid cells with no data were assigned a value of "null" - i.e., no data exists.

After gridding was completed, the raster digital elevation model (surface) was inspected for any remaining noise such as spikes and wells and these were removed prior to final export as an ASCII .xyz file.

SPCMSC Processing - The ASCII xyz file was converted to an ArcGIS multipoint feature using the 'ASCII 3D To Feature Class' tool within ArcCatalog 10.1. The output feature class was reprojected from the State Plane Coordinate System (NY, Long Island Zone) to NAD83 UTM Zone 18N.
