information
These files contain topographic and bathymetric lidar data collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast
of Wisconsin. 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 format of the files was LAS version 1.0.
The NOAA Office for Coastal Management received the data and converted the topo and hydro files from NAVD88 heights to ellipsoid heights using GEOID03.
These files were converted for data storage and Digital Coast provisioning purposes. The data are classified as:
1 - Unclassified
2 - Ground
11 - Bathymetry

These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above and below the water line in the Wisconsin
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.
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 topographic data as a series of LAS files with a single file per flightline per 5 km box and the bathymetric data
files contain all of the returns from the bathymetric sensor which includes returns both above and below the water.
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 classified as 0 (never classified) and received in geographic coordinates (NAD83) and
vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were meters. The hydro files were unclassified and received
in geographic coordinates (NAD83) and vertically referenced to NAVD88. 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 orthometric (NAVD88) heights to ellipsoidal heights using Geoid03.
4. The hydro ascii files were converted from ascii format to las format and the points were reclassified from 0 to 11 (Bathymetry).
