These files contain topographic and bathymetric lidar data collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the
coastline of the island of Isle Royale, Michigan in Lake Superior. 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 Geographical 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 were referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID03 model was used to transform
the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The positions are relative
to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to orthometric heights (NAVD88) using the Geoid03 model
with the results in meters. Once converted to geoid heights, the data were then converted to IGLD85 using the VDatum program from NOAA (National Oceanic
and Atmospheric Administration). The NOAA Office for Coastal Management received the data and converted the hydro files from IGLD85 heights to NAVD88 heights using
VDatum. The heights were then converted to ellipsoid heights using Geoid03. The topo files were converted from NAVD88 heights to ellipsoid heights
using Geoid03. These files were converted for data storage and Digital Coast provisioning purposes.
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.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above and below the water
along the Michigan coastal zone.

Conceptual Consistency
The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters,
and different flight line data agreed within 0.20 meters.
The USACE collected, processed, and provided the data to the NOAA Office for Coastal Management (OCM). OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https.
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 1Hz. 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 data as a series of first return topography (TF), last return topography (TL) and bathymetry (H) ASCII files. The bathymetry files contain all of
the returns from the bathymetric sensor which include returns both above and below the water. The data are converted from ellipsoid to orthometric heights,
based on the GEOID03 model, within the chartsLAS program. The data were then shifted vertically from the orthometric heights to IGLD 85 using VDatum software
from NOAA.
The NOAA Office for Coastal Management (OCM) received the topo files in LAS v1.1 format and the hydro files in ascii format. The files contained lidar
elevation and intensity measurements. The topo data were received in geographic coordinates (NAD83) and vertically referenced to NAVD88 using
the Geoid03 model. The vertical units of data were meters. The data were classified according to ASPRS LAS classification scheme (1 = unclassified,
2 = ground). The hydro files were received in geographic coordinates (NAD83) and vertically reference to IGLD85. OCM performed the following
processing for data storage and Digital Coast provisioning purposes:
1. Both topo and hydro files were filtered for elevation outliers.
2. The topo las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03.
3. The hydro ascii files were converted from IGLD85 heights to orthometric (NAVD88) heights using VDatum.
4. The hydro las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03.
5. The hydro ascii files were converted to las format and points were classified as 11 (Bathymetry)

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
