Abstract

Woolpert, Inc. was contracted to acquire and process high-resolution topo-bathy lidar to support mapping and modeling needs at the Sleeping Bear Dunes National Lakeshore (SLBE), which will be used for the creation of new benthic mapping products using the Coastal and Marine Ecological Classification Standard (CMECS). Woolpert sub-contracted NV5 to acquire the lidar data using their HawkEye 4X topo-bathy lidar sensor, to provide high density topo lidar with an ANPS of greater than or equal to 1 pulse per square meter with a vertical accuracy of less than or equal to a 15 cm RMSE for the bathymetric lidar.

Woolpert also collected topographic ground control and check points covering some extended survey lines.

This dataset is the classified lidar point cloud in LAS v. 1.4 format. collected on August 31 and September 3, 2021 using a Leica HawkEye4X sensor. Classifications are as follows: 1 - Unclassified, 2 - Ground, W7 - Low Point (Noise), 9 - Water Surface Topo, W18 - High Noise, 40 - Bathymetric Point, 41 - Water Surface Bathy, S42 - Derived Water Surface, 43 - Submerged Object, W45 - No Bottom Found At

In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

Purpose:

This project has two primary goals to fill critical gaps in our understanding of benthic habitat within Lake Michigan at Sleeping Bear Dunes National Lakeshore (SLBE). The first goal is the collection of new bathymetric lidar to support multiple agencies including the National Park Service, Michigan Department of Natural Resources, NOAA, and other region partners mapping and modeling needs by expanding existing high resolution bathymetry coverage around SLBE. The second goal is to use this bathymetry in the creation of new benthic mapping products using the Coastal and Marine Ecological Classification Standard (CMECS).

Data Quality

Vertical Positional Accuracy:

Absolute vertical accuracy for the lidar points was calculated using the check points. All check points were located on flat surfaces with no vegetation underneath the daily QC line. No check points were used to adjust the lidar data. This dataset was tested to meet 0.032 m RMSEz, equating to 0.063 meters at a 95% confidence interval.

Process Steps

Process Step 1

CC ID: 1146569
Description:

All lidar data were acquired using a Leica HawkEye4X topographic and bathymetric lidar system. The main sensor head, which contains the topographic laser, shallow bathymetric laser and RCD30 camera, was mounted in a Leica PAV100 gyro-stabilized mount integrated with a NovAtel SPAN GNSS and LCI-100C IMU. The deep channel bathymetric sensor head was installed using a separate fixed mount, with its own LCI-100C IMU. Real time navigation and GNSS/IMU data logging was provided by Leica FlightPro software. Lidar data were logged on the Airborne Hydrography, AB (AHAB) operator console. The HE4X provided 300 kHz topographic data, 140 kHz shallow bathymetric data and 40 kHz deep bathymetric data. 4-band 80 MP digital camera imagery was also collected simultaneously with the sensor's RCD-30 camera to assist with editing. Trajectory data were post-processed using NovAtel Inertial Explorer software to provide a tightly coupled precise point position (PPP) and orientation solution. Lidar data were processed in Leica's Lidar Survey Studio (LSS) using calibration data and final processed trajectory information to create an accurately georeferenced lidar point cloud for the entire survey in LAS v1.4 format. All points from the topographic and bathymetric laser include 16-bit intensity values. LAS files from LSS were imported to a Terrascan project where spatial algorithms were used to remove noise and classify bare earth/ground. Manual review was conducted in Terrascan prior to product creation. Woolpert used proprietary in-house scripts to compute project specific correction parameters and normalize the raw bathymetric intensity data for depth. This provides intensities that more closely represent the reflectance of the actual seabed. Corrected values are included in the provided LAS files. During lidar processing any line to line vertical mismatches are removed. Due to the lack of ground control in the survey area, a lidar QC flightline was acquired over the same area for every flight. This line covered ground control on land, out to full bathymetric depth. This line was used to test for accuracy. Interswath or overlap consistency for the topographic laser was assessed in all areas of overlap with slopes of less than 10 degrees. The topographic RMSDz for the project lines is 0.022 m. Interswath or overlap consistency for the bathymetric laser was assessed in all areas of overlap with slopes of less than 10 degrees. The bathymetric RMSDz for the project lines is 0.064 m. All data are provided in NAD83(2011) Epoch 2010.0. All units in meters. All lidar data was transformed to the NAVD88 vertical datum using GEOID18. Delivered LAS Classes include: 1-Unclassified, 2-Ground, W7-Low Point(Noise), 9-Water Surface Topo, W18-High Noise, 40-Bathymetric Point, 41-Water Surface Bathy, S42-Derived Water Surface, 43-Submerged Object, W45-No Bottom Found At. One charted wreck was found during data editing. The approximate location of this wreck is 45 degrees 02'21.6"N, 85 degrees 59'6.5"W and is captured in the anomalies shapefile included with the project deliverables.

Process Step 2

CC ID: 1146570
Description:

The NOAA Office for Coastal Management (OCM) received 631 LAS files from Woolpert. The files contained lidar elevation and intensity measurements. The data were in UTM Zone 16N NAD83(2011), meters coordinates and NAVD88 (Geoid18) elevations in meters. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Converted from UTM Zone 16N NAD83(2011), meters coordinates to geographic coordinates 2. Converted from NAVD88 elevations to ellipsoid elevations using the Geoid18 model 3. Sorted by gps time 4. Compressed the data using laszip
