These files contain rasterized, bare earth topobathy lidar elevations at a 1 m grid size, generated from data collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system. CZMIL integrates a lidar sensor with simultaneous topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 National Adjustment of 2011 (NAD83 NA11). Vertical positions are referenced to NAVD88 and provided in meters. The data file naming convention is based on the year, effort, area name, "Box" number and product type. An example file name is "2016_NCMP_MI_Superior_16TDT0423_BareEarth_1mGrid", where 2016 is the year of data collection, NCMP is the project under which data were collected, Michigan_Superior is the area of data collection, 16DT0423 is the "Box" number , and BareEarth 1mGrid is the product type. In addition to the bare earth DEMs, the topobathy lidar point data are also available. These data are available for download here: https://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=5187 DEMs that were created from all classes of points (1, 2, 29) at a 1 meter grid size are available by request via email at: coastal.info@noaa.gov

Completeness Report
This data set covers the spatial extent of topographic lidar data obtained during this survey.
Conceptual Consistency
During inspection and QC of the lidar point cloud, flightline to flightline elevation differences met the CZMIL sensor specifications.
These data were collected using the CZMIL system. It is owned and operated by the U.S. Army Corps of Engineers (USACE). The system collects topo/bathy lidar data at 10 kHz and RGB imagery at 2 Hz. 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 510 equipment. All raw data streams are transferred to the office for downloading and processing in CZMIL's Hydro Fusion 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 software then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID12B model and exports valid lidar data as a series of unclassified LAS files.
2016-09-20T00:00:00
LAS files are imported into GeoCue V2014.1.21.1, which is a geospatial workflow production and management software tool employed by JALBTCX to perform and monitor production of data products. Upon import into GeoCue, A customized classification macro, built upon the TerraScan V15 module within MicroStation V8i, classifies valid topobathy data as ground points (2), unclassified points (1), and bathymetric points (29). Upon completion the macro, the classification results undergo quality control and any misclassified points are manually edited. In areas of dense vegetation the bare earth 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. They are partitioned into a series of 5km or quarter quad delivery boxes, one Classified LAS file per box. The format of the file is LAS version 1.2. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data).
2016-12-23T00:00:00
Data is then converted from NAVD88 vertical datum to the IGLD85 vertical datum using NOAA's Vdatum program.
2016-12-23T00:00:00
Data classified as ground points (2) and bathymetric points (29) in the las files are converted to a grid by generating a triangulated irregular network (TIN) and then 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 V8 to perform this operation utilizing the following parameters; "Legacy Triangulation", "Max Sample Excursion - 30000", "Max Triangle Side - 30000", "Radius - none", "Tolerance - 1", 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 V10.1, the ASCII Z grid file is converted to a tiff-format raster file whose projection is defined as "The North American Datum of 1983 (2011)." The raster is then multiplied against a corresponding 1m Grid mask raster, a mask image produced from JALBTCX's 1m Grid, in ESRI's Raster Calculator to remove interpolated areas where data does not exist.
2016-12-23T00:00:00
The NOAA Office for Coastal Management (OCM) received data in tif format from JALBTCX. The bare earth raster files were at a 1 m grid spacing. The data were in geographic coordinates and IGLD85 elevations in meters. OCM converted the raster files from IGLD85 elevations to NAVD88 elevations using NOAA NGS VDatum. The files were then ingested into the Digital Coast Data Access Viewer (DAV) system for data storage and provisioning purposes.
