Description:

Abstract:

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center in Florida and the U.S. Army Corps of Engineers Field Research Facility in Duck, North Carolina, collaborated to gather alongshore ground-based lidar beach elevation data at Fire Island, New York. This high-resolution elevation dataset was collected on April 10, 2013, to characterize beach topography following substantial erosion that occurred during Hurricane Sandy, which made landfall on October 29, 2012, and multiple, strong winter storms. The ongoing beach monitoring is part of the Hurricane Sandy Supplemental Project GS2-2B. This USGS data series 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 km of Fire Island, NY beach, from the western boundary of Fire Island National Seashore to the Wilderness Breach.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Areas of data overlap were initially compared against each other to measure repeatability. Depending on GPS quality and distance from the base station, the accuracy of the scans varied from 5 to 15 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 Oceanic 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 10, 2013. The survey vehicle traveled approximately 5 kilometers per hour (km/h) along two 30 km shore parallel transits. The seaward side of the dune and the upper beach were surveyed during the first transit, and the area from near the shoreline and the lower beach were surveyed during the second transit. The survey was designed to provide an area of extensive overlap used to verify system accuracy and assess survey precision

Process_Description:

Data for the survey extents was collected along with a bore-sight to resolve subtle differences between the scanner and the inertial measurement unit (IMU). After collection, the data were post-processed with multiple software packages to produce the final digital elevation model product.

Process_Description:

Terrestrial GPS data are post-processed with National Geodetic Survey's (NGS) continuously operating reference stations (CORS) and integrated with post-processed IMU and DMI data within Applanix's PosPac software to derive a smoothed best estimate of vehicle trajectory (SBET). After processing, quantitative quality-metrics were analyzed to ensure the trajectory accuracy met the manufacturer's specified values.

Process_Step:

Process_Description:

The SBET and bore-sight measurements are imported into Riegl's RiProcess lidar software where the lidar point cloud is geo-rectified. Control monuments and previously validated data are used for comparison to determine the accuracy of the survey. The processed point cloud is manipulated within RiProcess to delineate the shoreline, filter structures and vegetation, and classify points as water, vegetation, structures, and ground. The classified point cloud is exported as a .las file.

Process_Description:

The .las file is imported into Applied Imagery's Quick Terrain Modeler software in which a mean-z (elevation) algorithm and an anti-aliasing filter are applied to the point-cloud data to grid the data at a 0.5 meter (m) resolution. After gridding is completed, the DEM (surface) is inspected for any remaining noise, such as spikes and wells, which are removed prior to final export as an American Standard Code for Information Interchange (ASCII) .xyz file. Any grid cells with no data were assigned a value of "null".

Within Esri’s ArcCatalog, the ASCII xyz file was converted to an ArcGIS multipoint feature using the ASCII 3D To Feature Class tool and was projected from North American Datum of 1983 (NAD 83) State Plane New York Long Island (meters) to NAD 83, Universal Transverse Mercator (UTM) Zone 18N (meters). The point data were converted back to ASCII xyz format for publication using the Feature Class Z to ASCII tool.

Process_Step:

Process_Description:

The uncertainty for the interpolated DEM was determined using a methodology established by Lentz and Hapke (2011) and Lentz and others (2013) by withholding a random distribution of 10 percent of the point data from the gridding process (Create Terrain and Build Terrain tools in ArcGIS), comparing the elevations of the withheld points to the gridded surface, and calculating a root mean square error (RMSE) on the basis of the elevation differences. The resulting RMSE uncertainty of the interpolated surface was determined to be ±0.026 m. The Terrain to Raster tool in ArcGIS was then used to export the surface raster with 1-m cell size for publication.
