The data sets are generated using the OPTECH ALTM 70 kHz LIDAR system mounted onboard AeroMap's twin-engine
Cessna 320 aircraft. Classified data sets such as this one may have varying posting due to some LIDAR pulses not
reaching the ground caused by data anomalies. Accuracy statements are based on areas of moderate terrain. Diminished
accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected
to meet the vertical accuracy standard; however, derived products may be less accurate in extreme terrain and dense
vegetation due to a lesser number of points defining the bare-earth in these areas. The data were QA/QC'ed but some
data holidays still exist. This data represents the last return data only.

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
The purpose of this data set is to provide a source for current and accurate digital elevation models (DEM) with
vertical accuracy's of 30cm root mean square error (RMSE) or better. These data were acquired at flying heights of 1200
and 2000 meters Above Mean Terrain (AMT) with post spacing planned for 1 and 2 meters. This data is not recommended for
design mapping or engineering. A DEM is used as a fundamental layer of information in Geographic Information Systems (GIS).
A number of the priority layers of spatial information recognized by the National Spatial Data Infrastructure may be derived
from LIDAR DEMs, including elevation, hydrography, slope, aspect, and shoreline delineation.
This data set was developed for the NOAA OCM by AeroMap US.

The raw points for the point cloud data product were captured using AeroMap U.S.'s twin-engine Cessna equipped with our OPTECH ALTM 70 kHz LIDAR data acquisition system. The system includes differential GPS and inertial measurement systems to provide superior accuracy. The flying height is 1200 & 2000 meters Above Mean Terrain (AMT). These data were post-processed utilizing Optech's REALM (Version 3.5.4) software, which applies AeroMap U.S.'s Applanix Inertial Measurement Unit (IMU) values to the acquired Airborne Global Positioning Systems (ABGPS) data. These results are then applied to the acquired LIDAR data points and output to a LIDAR accuracy standard (LAS) format in a WGS 84, Universal Transverse Mercator (UTM), Zone 3, Meters coordinate system. Using Bentley's Microstation V8 LIDAR these data were imported in LAS format. Using TerraSolid's TerraScan (version 6.04) software, these data were imported into a TerraScan project files (PRJ) and converted (on import) to a binary files, no data were classified, all original "point cloud" data as output from REALM. These data were then output to the deliverable ASCII, space delimited, CTIXYZ format, (see attribute section for explanation of ASCII file syntax).

The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained lidar intensity and elevation measurements. OCM performed the following processing on the data to make it available within the Lidar Data Retrieval Tool (LDART):
1. All data points in the ASCII files were projected geographic decimals degrees using the USGS General Cartographic
Transformation Package (GCTP) software.
2. All ASCII files containing points collected on the same date were combined into a single file and sorted by latitude.
3. The sorted files were then converted to binary LAS files and the las header fields were updated.
4. Data was QA/QC'ed and many points removed - there still remains several 'data holidays' as unique outliers in otherwise
ordered areas. They can be manually edited by user if required. This data represents the last return data only.

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID12B) meters, using the GEOID12B 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)
