These files contain bare-earth classified topographic and bathymetric lidar data collected July 27, 2009 by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of Lake Superior near Duluth, Minnesota. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera, and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). The topographic lidar sensor has a pulse repetition rate of 9 kHz at 1064 nm (near-infrared wavelength). The bathymetric lidar sensor has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). 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, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). For data storage and provisioning purposes, the NOAA Office for Coastal Management converted the data from NAVD88 heights to ellipsoid heights using GEOID03.
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.

These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above the water in the Minnesota and Wisconsin coastal zone.

High water turbidity in the survey area hindered the acquisition of bathymetric data in box 01 and resulted in incomplete coverage.

These data were collected using the CHARTS system. It is owned by the Naval Oceanographic Office and operated through contract.
The system collects topographic lidar data at 9 kHz, bathymetric lidar data at 1 kHz and RGB imagery at 1 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 410 equipment. All raw data streams are transferred to the office
for downloading and processing in SHOALS GCS 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's chartsLAS module then converts all valid data
from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports topographic data as a series of LAS files with
a single file per flightline per 5 km box.

The NOAA Office for Coastal Management (OCM) received unclassified files in las format. The files contained LiDAR intensity and
elevation measurements. OCM performed the following processing on the data for data storage and Digital Coast provisioning:
1. The data were bare-earth classified using MARS Explorer 6.1 software.
2. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03.
3. The LAS header fields were sorted by latitude and updated.
