Abstract

These files contain rasterized bare earth topobathy lidar elevation data at a 1 meter grid spacing, along the coast of Oregon, 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. The 3-D position data are used to generate a series of gridded file products, which are tiled into quarter-quads or 5km boxes.

In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEMs 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.

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.

Process Steps

Process Step 1

CC ID: 1290670
Description:

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 CZMILs 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' GEOID12A model and exports valid lidar data as a series of unclassified LAS files.
Process Date/Time: 2014-10-02 00:00:00

Process Step 2

CC ID: 1290671
Description:

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), 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 algorithms 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).
Process Date/Time: 2015-07-02 00:00:00

Process Step 3

CC ID: 1290672
Description:

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 V10.2, 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 JALBTCXs 1m Grid, in ESRIs Raster Calculator to remove interpolated areas where data does not exist.
Process Date/Time: 2015-07-09 00:00:00

Process Step 4

CC ID: 1290673
Description:

The NOAA Office for Coastal Management (OCM) received the 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 orthometric (NAVD88) elevations in meters. OCM copied the raster files to https for Digital Coast storage and provisioning purposes.
