These data were collected by the SHOALS (Scanning Hydrographic Operational Airborne Lidar Survey) system which consists of an airborne laser transmitter/receiver
capable of measuring 400 soundings per second. The system operates from a deHavilland DHC-6 Twin Otter flying at altitudes between 200 and 400 meters with a
ground speed of about 100 knots. The SHOALS system also includes a ground-based data processing system for calculating acurate horizontal position and water depth.
Lidar is an acronym for LIght Detection And Ranging. The system operates by emitting a pulse of light that travels from an airborne platform to the water surface where a small
portion of the laser energy is backscattered to the airborne receiver. The remaining energy at the water's surface propogates through the water column and reflects off the
sea bottom and back to the airborne detector. The time difference between the surface return and the bottom return corresponds to water depth. The maximum depth
the system is able to sense is related to the complex interaction of radiance of bottom material, incident sun angle and intensity, and the type and quantity of organics
or sediments in the water column. As a rule-of-thumb, the SHOALS system should be capable of sensing bottom to depths equal to two or three times the Secchi depth.

Accuracy
SHOALS has demonstrated capabilities that meet US Army Corps of Engineers Hydrographic Survey accuracy requirements for Class 1 surveys and the International
Hydrographic Organization nautical charting standards for Order 1.
Horizontal Positional Accuracy
+/- 3 meters (1 sigma); Quantitative Value: 3.0 meters, Test that produced the value: Not tested, compiled to meet value (meters) at 1 sigma (1 standard deviation).
Vertical Positional Accuracy
+/- 15 cm (1 sigma); Quantitative Value: 0.15 meters, Test that produced the value: Collected to meet value (meters) at 1 sigma (1 standard deviation)

The SHOALS airborne system acquires a tremendous volume of raw data during a single mission. The lidar data are unique and require a specialized Data Processing
System (DPS) for post-processing. The DPS main funcions 1) import airborne data stored on high density data tape; 2) perform quality control checks on initial
depths and horizontal positions; 3) provide display and edit capabilities; 4) calculate depth and position (XYZ) values for each sounding; and 5) output final positions
and depths for each sounding.

The NOAA Office for Coastal Management (OCM) received topographic files in ASCII format. The files contained
bathymetric depth measurements. Some sections of the data were received in NAD27 Hawaii State Plane (various zones), other sections
were received in NAD27 UTM Zones 4 and 5. The data were vertically referenced to MLLW (feet or meters). OCM performed the following processing for
data storage and Digital Coast provisioning purposes:
1. The topographic las files were converted from Projected coordinates (State Plane or UTM) to Geographic coordinates.
2. If the vertical units were feet they were converted to meters.
3. The data were converted from ASCII to LAS V1.2
4. All points were classified to Class 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)
