        abstract:  These files contain rasterized topographic lidar elevations generated from returns classified as ground (2). These data were collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of New York. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). Native lidar data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages are used to processes the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis.The 3-D position data are used to generate a series of gridded file products, with each covering approximately 5 kilometers of shoreline. The grid file index is provided by the shape file, "ny_boxes.shp", and the numbers used to identify files are in the "Box" field of the shape file. The data file naming convention is based on the year, project, area name, "Box" number and the product type. An example file name is "2010_NCMP_NY_01_BareEarth_1mGrid.tif", where 2010 is the year of data collection, NCMP is the project under which data were collected, NY is the area of data collection, 01 is the "Box" number and "BareEarth_1mGrid" is the product type. In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
        purpose:  These data were collected as a part of the NCMP to depict the elevations above water in the New York coastal zone.

        supplementalInformation:  There was significant coastal change in the survey area of project 2010_NCMP_NY. During data product production it was not possible to combine topographic (red laser) data coverage obtained August 13, 2010 in boxes 09 to 23 w/ the bulk data coverage collected before and after. It would have resulted in change-induced artifacts (e.g. double beach berms) in the data products. Where possible, bathymetric (green laser) data was used to fill gaps resulting from exclusion of the August 13, 2010 data. However, there still remains an approximately 2 km long data gap in 2010_NCMP_NY Box 11. Data obtained on the 13th is delivered as products in the project 2010_NCMP_NY_A.

            statement:  The USACE collected, processed, and provided the data to the NOAA Office for Coastal Management (OCM). OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https.
            processStep:  (LI_ProcessStep)
                description:  These data were collected using the CHARTS system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 9 kHz, bathymetric lidar data at 1 kHz and RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V 410 equipment. All raw data streams are transferred to the office for downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE's chartsLAS module then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports topographic data as a series of LAS files with a single file per flightline per 5km box.
            processStep:  (LI_ProcessStep)
                description:  The flightline LAS files are imported into the TerraScan V11 module within MicroStation V8.0. The resulting LAS files are thinned to eliminate duplicate points. A customized classification macro is used to distinguish ground points (2) and unclassified points (1). The classification results are QC'd and any misclassified points are manually edited. In areas of dense vegetation the bare ground points might be incorrectly classified due to the inability of the laser to penetrate the canopy and reach the bare ground. In these areas, JALBTCX defaults to the algorithm's "ground" surface instead of manually reclassifying those points. The points are exported to an ASCII file containing the following fields: longitude, latitude, elevation (orthometric), intensity, classification, mirror angle, time (GPS time), number of echos, and echo number. The ASCII file is converted to LAS using txt2las code from LAStools (http://www.cs.unc.edu/~isenburg/lastools/).
            processStep:  (LI_ProcessStep)
                description:  The points classified as ground in the Classified LAS files are exported from TerraScan V11 and converted to a grid by generating a Triangulated Irregular Network (TIN) and the extracting the grid node elevations from the TIN surface. The origin point of the grid is located at a horizontal position whose value is evenly divisible by the 1m grid resolution such that rasters from subsequent surveys have common cell boundaries. JALBTCX uses Quick Terrain Modeler V7.1.1 to perform this operation utilizing the following key parameters; “Max Sample Excursion 50,” “Max Triangle Side 100,” “Smoothing filter Level 4 with a Max Roughness 2, and "Tiling Settings Snap to Grid (Expand).” The grid is exported from Quick Terrain Modeler as an ESRI ASCII Z grid file. Utilizing an in-house python script within ESRI ArcMap V10, the ASCII Z grid file is converted to a tiff-format raster file whose projection is defined as “The North American Datum of 1983.” Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88).
            processStep:  (LI_ProcessStep)
                description:  The NOAA Office for Coastal Management (OCM) received GeoTiff format files from USACE JALBTCX for the New York coastline project area. The bare earth raster files were at a 1 m grid spacing. The data were in geographic NAD83 coordinates and NAVD88 (Geoid03) elevations in meters. OCM assigned the appropriate EPSG codes (Horiz - 4269, Vert - 5703) and copied the raster files to https for Digital Coast storage and provisioning purposes.
