Abstract

These data were collected on behalf of the USACE, Northwest Division, Portland District (NWP) in the area of Coos Bay, Oregon. 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 imagery 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, are in decimal degrees of latitude and longitude, referenced to the North American Datum of 1983 National Adjustment of 2011. Vertical positions were collected to the NAD83(2011) ellipsoid and 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). 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, 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 and 5 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. Please provide the name of the data set and "DEM Request" in the subject line.

Data Quality

Accuracy:

These data are not attributed. | Quantitative Value: None | Quantitative Test Explanation: These data are not attributed.

Horizontal Positional Accuracy:

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of CZMIL in the joint topo/bathy mode of operation is +/- 1 m, 2 sigma.; Quantitative Value: 1.0 meters, Test that produced the value: +/- 1 m, 2 sigma

Vertical Positional Accuracy:

Topo data - 19.6 cm @ 95% confidence level (10 cm RMSE). Bathy shallow FOV data - SQRT((0.25^2)+((0.0075d)^2)) meters at @ 95% confidence level. Bathy deep FOV data - SQRT((0.30^2)+((0.013d)^2)) meters @ 95% confidence level (d is depth).; Quantitative Value: 0.10 meters, Test that produced the value: +/- 10 cm RMSE

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.

Lineage

Process Steps

Process Step 1

CC ID: 1147057
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 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.

Process Date/Time: 2014-10-02 00:00:00

Process Step 2

CC ID: 1147058
Description:

LAS files are imported into GeoCue V2012.1.27.7, 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).

Process Date/Time: 2015-07-02 00:00:00

Process Step 3

CC ID: 1147059
Description:

The NOAA Office for Coastal Management (OCM) received the files in las format from JALBTCX. The files contained lidar elevation and intensity measurements. The data were in geographic coordinates and orthometric heights in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. LAS files were compressed to laz format using laszip. 2. Data were checked for elevation outliers. 3. Data were converted from orthometric heights to NAD83(2011) ellipsoid heights using GEOID12A.
