49738 gulf2016_usace_ncmp_gulf_m5186_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed 2017-09-13 These files contain classified topo/bathy lidar data along the coasts of Alabama, Florida, Mississippi, and Texas. In Florida, the data were collected on behalf of the National Park Service. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data). Classes 1 and 2 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. These data were 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. 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 process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. In addition to the lidar point data, topobathy bare earth Digital Elevation Models (DEMs), at a 1 meter grid spacing, created from the lidar point data are also available. A link to custom download this data is provided in the URL section of this metadata record. 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. These products have not been reviewed by the NOAA Office for Coastal Management (OCM) and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or OCM.

This data set covers the spatial extent of topographic lidar data obtained during this survey. During inspection and QC of the lidar point cloud, flightline to flightline elevation differences met the CZMIL sensor specifications. 1 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 topobathy 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 and have the withheld bit set. PFM_ABE software then exports valid lidar data as a series of unclassified LAS files. 2016-09-09T00:00:00 2 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 V16 module within MicroStation V8i, classifies valid topobathy data as ground points (2) and unclassified points (1), and valid 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). 2017-05-24T00:00:00 3 For the data in Texas, the NOAA Office for Coastal Management (OCM) received files in laz 1.2 format. The files contained lidar intensity and elevation measurements for the project area. Horizontal positions were provided in geographic coordinates, referenced to the North American Datum of 1983 National Adjustment of 2011 (NAD83 NA11). Vertical positions were provided in NAVD88 elevations (Geoid12b) and in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. Converted the laz files from NAVD88 elevations to ellipsoid elevations using Geoid12b. 2. Sorted by gpstime 3. Compressed the data using laszip 4. Copied the laz files to database and https 2017-12-04T00:00:00 4 For the data in Alabama, Florida, and Mississippi, the NOAA Office for Coastal Management (OCM) received files in laz 1.2 format.
