49750 hi2013_usace_ncmp_maui_lmsl_m5032_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed 2016-04-13 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 National Adjustment of 2011 (NAD83 PA11). 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 5km boxes. In addition to the lidar point data, 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. These data were collected as a part of the NCMP to depict the elevations above and below the water in the Hawaii coastal zone. 10394 A footprint of this data set may be viewed in Google Earth at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/msl/5032/supplemental/hi2013_usace_ncmp_maui_lmsl_m5032.kmz Theme ISO 19115 Topic Category elevation Theme CoRIS Discovery Thesaurus lidar Theme CoRIS Theme Thesaurus EARTH SCIENCE > Land Surface > Topography> Terrain Elevation Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Bathymetry/Seafloor Topography > Bathymetry Theme NOAA NOS Harvest Catalog CoRIS Theme IWG-OCM Theme National Coastal Mapping Program (NCMP) Theme U.S. Army Corps of Engineers (USACE) Temporal 2013 Temporal December Temporal November Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Hawaii > Maui > Maui Island (20N156W0004) Spatial CoRIS Place Thesaurus OCEAN BASIN > Pacific Ocean > Central Pacific Ocean > Hawaiian Islands > Maui Island > Maui Island (20N156W0004) Office for Coastal Management Charleston SC Data Set As Needed LAS 1.2 format (classes 1,2,29) none Any conclusions drawn from the analysis of this information are not the responsibility of JALBTCX, the Office for Coastal Management or its partners.

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. 2013-10-16T00:00:00 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 V13 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). Then the LAS files are adjusted to Local Mean Sea Level (LMSL). The Geoid12B to HI LMSL vertical adjustment value derived from published NGS control point datasheets for HI, The Maui, was -0.601m. 2015-12-16T00:00:00 3 The NOAA Office for Coastal Management (OCM) received files in las format from JALBTCX. The files contained LiDAR intensity and elevation measurements and derived products for the island of Maui. OCM performed the following processing on the data for storage purposes and to make it available within Digital Coast: 1. The LAS files were processed to remove outlier points but maintained original projection information. Tiles were delivered horizontally referenced to geographic coordinate system (decimal degress) and vertical heights are referenced to the LMSL in meters. 2016-03-31T00:00:00 64845 Data Set Cross Reference gov.noaa.nmfs.inport:49750 Anne Ball 2017-11-15T15:22:03 SysAdmin InPortAdmin 2022-08-09T17:11:36 2022-03-16 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
