These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl
Q680i-D system. The data includes topographic data in an LAS 1.2 format file classified as unclassified (1), ground (2), and water (9) in accordance
with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set also includes lidar intensity values
and encoded RGB image values.

This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's Coastal Mapping Program. It is not intended for mapping, charting, or
navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar.

Data include all lidar returns. "Outliers" or "false returns" (e.g., returns from birds, atmospheric particles, and/or system noise) may be present
in the data. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all
water returns were correctly classified; therefore the ground classification could proceed into water bodies, and should be removed by the user.

Data were processed to an initial LAS format using the Riegl RiProcess software. The Applanix POSPac software was utilized for GPS
and inertial processing, and Terrasolid software for data visualization, 3D editing, and export to final LAS file. Data were processed
in NAD83 horizontal and vertical datum.

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained LiDAR elevation as well as intensity
and encoded RGB image values. The data were in UTM, Zone 19 coordinates. OCM performed the following processing for data storage
and Digital Coast provisioning purposes:
1. The data were converted from UTM Zone 19 coordinates to geographic coordinates.
2. The data were filtered for outliers.
