Title: 2019 - 2020 NOAA NGS Topobathy Lidar DEM: Hurricane Michael (NW Florida)
Status: Completed
Publication Date: 2023-01
Abstract:

The 2019 - 2020 NOAA NGS Topobathy Lidar DEM: Hurricane Michael data were collected by multiple contractors including NV5 and Dewberry. The 100 meter buffered project area consists of approximately 2,120,060 acres encompassing the Florida Panhandle and extending south to New Port Richey, Florida, and was collected between November 2019 - July 2020 using a Leica Chiroptera 4X system. The dataset includes topobathymetric digital elevation model data in geoTIFF format at 1 meter horizontal resolution.

Purpose:

This lidar data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping (IOCM) initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar.

Supplemental Information:

An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all returns were correctly classified; therefore the user should examine for acceptability.

Data Quality

Horizontal Positional Accuracy:

Lidar horizontal accuracy is a function of Global Navigation Satellite System (GNSS) derived positional error, flying altitude, and INS derived attitude error. The obtained RMSEr value is multiplied by a conversion factor of 1.7308 to yield the horizontal component of the National Standards for Spatial Data Accuracy (NSSDA) reporting standard where a theoretical point will fall within the obtained radius 95 percent of the time (ACCr). Based on a flying altitude of 400 meters, an IMU error of 0.004 decimal degrees, and a GNSS positional error of 0.008 meters, the RMSEr value for the Delivery 1 area is 0.05 meters, with a ACCr of 0.09 meters at the 95% confidence level. The project specification requires horizontal positions to be accurate to 1.0m(RMSE).

Based on a flying altitude of 400 meters, an IMU error of 0.007 decimal degrees, and a GNSS positional error of 0.027 meters, the RMSEr value for the Delivery 2 area is 0.09 meters, with a ACCr of 0.16 meters at the 95% confidence level.

Process Steps

Process Step 1

CC ID: 1298953
Description:

Data for the NOAA Michael Topobathymetric Lidar project area was acquired by Quantum Spatial (QSI) using a Leica Chiroptera 4X Topobathy lidar system. All derived LAS data was referenced to:

Horizontal Datum-NAD83(2011) epoch: 2010.00

Projection-UTM Zone 16N and UTM17N

Horizontal Units-meters

Vertical Datum-GRS80 Ellipsoid

Vertical Units-meters

The collected Lidar data were immediately processed in the field by QSI to a level that will allow QA\QC measures to determine if the sensor is functioning properly and assess the coverage of submerged topography. An initial SBET was created in POSPAC MMS 8.3 SP3 and loaded into RiProcess which applies pre-calibrated angular misalignment corrections of scanner position to extract the raw point cloud into geo-referenced LAS files. These files were inspected for sensor malfunctions and then passed through automated raster generation using LAStools to develop an initial assessment of bathymetric coverage. QSI reviewed all acquired flight lines to ensure complete coverage and positional accuracy of the laser points. These rasters were also used to create an initial product in Quick Look Coverage Maps. These Quick Look files are not fully processed data or final products but provide rapid assessment of approximate coverage and depth penetration.

QSI resolved kinematic corrections for aircraft position data using aircraft GNSS and Applanix's proprietary PP-RTX solution. When PP-RTX was not used QSI conducted static Global Navigation Satellite System (GNSS) ground surveys (1 Hz recording frequency) using base stations over known monument locations during flights. After the airborne survey, static GPS data were triangulated with nearby Continuously Operating Reference Stations (CORS) using the Online Positioning User Service (OPUS) for precise positioning. Multiple independent sessions over the same base station were performed to confirm antenna height measurements and to refine position accuracy.

This data was used to correct the continuous on board measurements of the aircraft position recorded throughout the flight. A final smoothed best estimate trajectory (SBET) was developed that blends post-processed aircraft position with attitude data. Using the SBETs, sensor head position and attitude were then calculated throughout the survey. Trimble Business Center v.3.90, Blue Marble Geographic Calculator 2019, and PosPac MMS 8.3 SP3 were used for these processes.

Following final SBET creation, QSI used Leica Lidar Survey Studio (LSS) to calculate laser point positioning by associating SBET positions to each laser point return time, scan angle, and intensity. Leica LSS was used to derive a synthetic water surface to create a water surface model. All LiDAR data below water surface models were classified as water column to correct for refraction. 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 tool corrects for this difference by adjusting the depth (distance traveled) and horizontal positioning (change of angle/direction) of the LiDAR data. Using raster-based QC methods, the output data is verified to ensure the refraction tool functioned properly.

Dewberry performed the calibration of the NOAA Michael Delivery 1 Lidar dataset in addition to the point cloud classification in order to create the final topobathymetric lidar deliverables which were subsequently reviewed by QSI.

Process Step 2

CC ID: 1298954
Description:

Relative accuracy of the green swaths compared to overlapping and adjacent green swaths as well as the relative accuracy of green swaths compared to overlapping and adjacent NIR swaths was verified through the use of Delta-Z (DZ) orthos. Dewberry created DZ rasters using proprietary processing tools. The intraswath or within a swath accuracy were verified using GIS software. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths.

All lidar data was peer-reviewed. QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. NV5 Geospatial's proprietary software, LAS Monkey, 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.

The contractor delivered classification scheme is as follows:

1- Unclassified

2- Ground

7- Noise

40- Bathymetric bottom or submerged topography

41- Water surface

43- Submerged object

45- water column

46- overlap bathy bottom - temporally different from a separate lift

71- unclassified associated with areas of overlap bathy bottom/temporal bathymetric differences

72- ground associated with areas of overlap bathy bottom/temporal bathymetric differences

81- water surface associated with areas of overlap bathy bottom/temporal bathymetric differences

85- water column associated with areas of overlap bathy bottom/temporal bathymetric differences

1Overlap- Edge clip

1Withheld- Green laser returns in topo only areas

42Synthetic- derived water surface

All data was then verified by an Independent QC department. The independent QC was performed by separate analysts who did not perform manual classification or editing. The independent QC involved quantitative and qualitative reviews.

Process Step 3

CC ID: 1298955
Description:

Dewberry transformed the final LiDAR data from ellipsoid heights to orthometric heights referenced to NAVD88, Geoid12b to create the final topobathymetric void clipped DEMs. The topobathymetric bare earth DEMs were output at 1 meter resolution in GeoTIFF format into 5000 m x 5000 m tiles. The rasters are clipped to the extent of the project boundary and named according to project specifications.

A bathymetric void shapefile was created to indicate areas where there was a lack of bathymetric returns. This shape was created by triangulating bathymetric bottom points with an edge length maximum of 4.56m to identify all areas greater then 9 square meters without bathymetric returns. This shapefile was used to clip and exclude interpolated elevation data from these areas in the bathymetric void clipped topobathymetric bare earth model.
