These files contain classified topo/bathy lidar data. 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. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 Pacific Adjustment of 2011 (NAD83 PA11). Vertical positions were referenced to the (NAD83 PA11) ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID12A model was used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). Once converted to orthometric heights, the data are then adjusted to the Local Mean Sea Level (LMSL). The 3-D position data are sub-divided into a series of LAS files, which are tiled into quarter-quads or 5 km boxes. In addition to the lidar point data, topo/bathy Digital Elevation Models (DEMs), created from the lidar point data are also available. DEMs were created from all classes of points (1, 2, 29) at a 1 meter grid size and bare earth DEMs were created from the ground and bathymetric data classes (2, 29) at a 1 meter grid size. 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. The data are available upon request via email at: coastal.info@noaa.gov.

AS 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 V13 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 1km boxes, one Classified LAS file per box and converted to NAD83 2011 Geoid 12A.. 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). Then the LAS files are adjusted to Local Mean Sea Level (LMSL). The Geoid12A to HI LMSL vertical adjustment value derived from published NGS control point datasheets for HI, The Oahu, was 0.633m.

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 converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID12A model and exports valid lidar data as a series of unclassified LAS files.

The NOAA Office for Coastal Management (OCM) received 886 files in las format from JALBTCX. The files contained LiDAR intensity and elevation measurements for the island of Oahu. The data were in geographic coordinates and Local Mean Sea Level (LMSL) elevations in meters. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes:
1. The LAS files were compressed to laz format using laszip. 2. Data filenames were standardized to OCM file naming convention (retaining USACE names). 3. The LAStools software scripts lasinfo,lasvalidate, and lasduplicate were run on the laz files to check for errors. 4. Internal OCM scripts were run on the laz files to check for elevation outliers, to assign the correct geokeys, to sort the data by gps time and zip the data to database and to http.
