Abstract:

This is a bare earth data set. The data contained in these files contain hydrographic and topographic data collected by the CHARTS

system along the Lake Huron coast of Michigan from August 25 - September 26, 2007. The data were collected and processed in geographic

coordinates and ellipsoid heights. The positions were 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. For data storage and

provisioning purposes, the NOAA Office for Coastal Management converted the data from NAVD88 heights to ellipsoid heights using GEOID03.

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.

Purpose:

These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above the water for the last

return in the Michigan coastal zone.

Notes:

Supplemental Information:

These data covered the required survey area with minimal gaps in data coverage except boxes 16-27. There is no topo data covering these

areas. A footprint of this data set may be viewed in Google Earth at:

Lineage

Process Steps

Process Step 1

CC ID: 1138891
Description:

These data were collected using the CHARTS surveys system. It is owned by the Naval Oceanographic Office and operated through contract.

The system collects topographic lidar data at 20 kHz and hydrographic data at 3 kHz. The system also collects 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 equipment. Raw data are collected and transferred to the office for downloading

and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to

produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the

dataset. The data are converted from ellipsoid to orthometric heights, based on the GEOID03 model, within the chartsLAS program.

Process Step 2

CC ID: 1138892
Description:

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.
