The U.S. Army Corps of Engineers collects and maintains LiDAR data including orthophotos in coastal areas of the United States and its territories. The Corps acquires this data in the course of performing its mission of Flood Control, Navigation, Environmental Engineering, and support for the Army and others. These data were collected along the Indiana, Michigan, Ohio and Pennsylvania coasts of the Great Lakes using the CHARTS (Compact Hydrographic Airborne Rapid Total Survey) system and industry based coastal mapping and charting systems.

The purpose of this survey was to collect topographic and hydrographic elevations to obtain the existing conditions
of the beach and near shore in support of the Joint Airborne LiDAR Bathymetric Technical Center of Expertise National
Coastal Mapping Program. However, depths were not attained in many areas due to water clarity.

Acquisition - Data were acquired using a SHOALS-1000T. Sensor orientation was measured using a POS AV 410, while
images were acquired at 1Hz using a Duncantech DT4000 digital camera. Prior to survey PDOP was checked and missions
planned to avoid PDOP greater than 3.5. During survey the plane was always within 30km of a GPS ground control point,
to provide a good quality position solution. Final positions were determined using a post-processed inertially aided
Kinematic GPS (KGPS) solution. GPS ground control data were acquired at 1Hz.
Data received by the airborne system were continually monitored for data quality during acquisition operations. Display
windows showed coverage and information about the system status. In addition, center waveforms at 5Hz were shown. All
of this information allowed the airborne operator to assess the quality of data being collected.
The data were collected and processed in geographic coordinates and ellipsoid heights. The positions are
relative to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid
to geoid heights (NAVD88) using the Geoid03 model with the results in meters.
Data were processed in the field to verify coverage and data quality.
2
Processing - Data were processed using the SHOALS Ground Control System (GCS). The GCS includes links to Applanix POSPac
software for GPS and inertial processing, and IVS Fledermaus software for data visualization, 3D editing and tie-line
analysis. Data were processed in NAD83 horizontal and vertical datum. Data were later converted to the NAVD88 vertical
datum using the GEOID03 model. The date and time of each point are also MM:SS.SSSSSS.
Fugro in-house utilities were used to extract XYZ data from the native LiDAR files and split the data in to pre-defined
boxes, each covering approximately 5km of shoreline. ASCII files include: Longitude, Latitude, Elevation, Date, Time,
and Intensity.

Files converted to LDART LAS format (geographic coords, ellipsoid heights,using GEOID03),
sorted by latitude and filtered to eliminate outliers.

Times had originally been stored as POSIX seconds when converted to LAS. This was switched to adjusted GPS time (GPS seconds - 1e9) to conform to the LAS 1.2 standard.

NOAA OCM received the data in LAS v1.2 format. For data storage and Digital Coast provisioning purposes, the data were processed as follows:
1. Heights were converted Ellipsoid heights, horizontal coordinates were converted to geographic coordinates.
2. lastools's Lasground processed the all unclassifed points to have ground classified points as well.
3. LAS files were converted to LAZ and sorted.
