1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:

2022 NOAA NGS Topobathy Lidar DEM of Ta'u, American Samoa

Taken From: Item Identification | Title

1.2. Summary description of the data:

This data was collected by Woolpert using a Leica HawkEye 4X sensor. The data was acquired from 20221021 - 20221202. The data includes topobathy data in LAS 1.4 format classified as unclassified (1), ground (2), low noise (7), topo water surface (9), high noise (18), bathymetric point (40), bathymetric water surface (41), synthetic derived water surface (42), submerged object (43), International Hydrographic Organization (IHO) S-57 object (44), submerged aquatic vegetation (64), and bathymetric bottom temporal changes (65) in accordance with the project specifications. The lidar data in ellipsoid heights was used to create the final topobathymetric DEMs in ellipsoid heights.

Lidar data classes 2, 40 and 43 were used to generate a raster in geotiff format, with 1 meter pixel resolution for the entire area. The raster was then clipped to the tile grid and named according to project specifications to result in tiled 5000m x 5000m topobathymetric DEMs.The project consists of approximately 74 square kilometers of data collected in Tau, American Samoa. This dataset contains 7 5000 m x 5000 m raster tiles.

5. Data Lineage and Quality

NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.

5.1. Processing workflow of the data from collection or acquisition to making it publicly accessible
(describe or provide URL of description):

Process Steps:

2023-07-31 00:00:00 - Woolpert acquired, calibrated, and performed the refraction correction of the lidar data. Light travels at different speeds in air versus water and its direction of travel or angle is changed or refracted when entering the water column. The refraction correction process corrects for this difference by adjusting the depth (distance traveled) and horizontal position (change of angle/direction) of the lidar data acquired within water. Relative accuracy of the swaths compared to overlapping and adjacent swaths was verified through the use of Delta-Z (DZ) orthos created in LASTools software. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths. The NovAtel software was utilized for GPS and inertial processing, Data were processed to an initial LAS format using the Leica Lidar Survey Studio software. Algorithms in TerraScan was used to create the initial ground surface. All lidar data was peer-reviewed. QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. LASTools was used to update LAS header information, including all projection and coordinate reference system information. The final lidar data is in LAS format 1.4 and point data record format 6.
2023-07-31 00:00:00 - The National Oceanic and Atmospheric Administration (NOAA) received files in laz format. The data is in UTM Zone 2S coordinates and ellipsoid elevations in meters. Horizontal Datum-NAD83 (PA11) epoch: 2010.0 Projection-UTM Zone 2 South Horizontal Units-meters Vertical Datum-NAD83 (PA11) Ellipsoid height Vertical Units-meters The final classification scheme is as follows: 1-Unclassified 2-Ground 7-Low Noise 9-Topo Water Surface 18-High Noise 40-Bathymetric Point 41-Bathymetric Water Surface 42-Synthetic Derived Water Surface 43-Submerged Object 44-International Hydrographic Organization (IHO) S-57 Object 64-Submerged Aquatic Vegetation 65-Bathymetric Bottom Temporal Changes The lidar data is referenced to the NAD83 (PA11) ellipsoid. The lidar data in ellipsoid heights was used to create the final topobathymetric DEMs in ellipsoid heights. Lidar data classes 2, 40 and 43 were used to generate a raster in geotiff format, with 1 meter pixel resolution for the entire area. The raster was then clipped to the tile grid and named according to project specifications to result in tiled 5000m x 5000m topobathymetric DEMs. Bathy void polygons represent bathymetric areas with no bathymetric bottom returns and accompany the DEMs. Void polygon creation is described in the final project report.
