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). Purpose: 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.

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 Logical_Consistency_Report: 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. Completeness_Report: 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.

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.

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.
