USGS Contract: G10PC00026
Task Order Number: G10PD00578
LiDAR was collected at a nominal pulse spacing of 2.0 meters for a 700 square mile area to
the east of Mobile Bay, either not previously surveyed using LiDAR sensors or where the collected
data was poor, while no snow was on the ground and rivers were at or below normal levels.
The goal of the NGOM LiDAR project in the post-Katrina environment is to provide scientific
knowledge and tools required to make optimal decisions about land resource use, management
practices, and future development in the northern Gulf of Mexico coastal zone. This regional
LiDAR elevation mapping data will be used for modeling, predicting landscape change, promoting
restoration of ecosystems, and mitigating risks associated with anthropomorphic and natural hazards.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
Classified LAS files are used to show the manually reviewed bare earth surface. Any additional
classification is provided via automated macro functionality from proprietary Photo Science TerraScan macros.
These additional classifications include Class 4 - Medium Vegetation and Class 5 - High Vegeation. This
allows the user to create Intensity Images, Break Lines, Raster DEM, and Triangular Irregular Networks.
Photo Science, Inc. flew the LiDAR and processed the data.

Accuracy
The project area requires LiDAR to be collected on average of 2.0 meter point spacing
or better and vertical accuracy of 15 centimeters RMSE or better to support 2' contour
generation when combined with breaklines.
Vertical Positional Accuracy
Classified LAS files were tested by Photo Science for both vertical and horizontal
accuracy. All data is seamless from one tile to the next, no gaps or no data areas.
The vertical unit of the data file is in decimal feet with 2-decimal point precision.
; Quantitative Value: 0.0013 meters, Test that produced the value: RMSE in meters
Completeness Report
Datasets contain complete coverage of tiles.
Conceptual Consistency
Classified LAS files were tested by Photo Science for both vertical and horizontal accuracy.
All data is seamless from one tile to the next, no gaps or no data areas.
Applanix software was used in the post processing of the
airborne GPS and inertial data that is critical to the positioning
and orientation of the sensor during all flights. POSPac MMS provides
the smoothed best estimate of trajectory (SBET) that is necessary
for Optech's post processor to develop the point cloud from the
LiDAR missions. The point cloud is the mathematical three dimensional
collection of all returns from all laser pulses as determined from
the aerial mission. At this point this data is ready for analysis,
classification, and filtering to generate a bare earth surface model
in which the above ground features are removed from the data set.
The point cloud was manipulated within the Optech software; GeoCue,
TerraScan, and TerraModeler software was used for the automated
data classification, manual cleanup, and bare earth generation from
this data. Project specific macros were used to classify the ground
and to remove the side overlap between parallel flight lines.
All data was manually reviewed and any remaining artifacts removed
using functionality provided by TerraScan and TerraModeler.
All Class 2 LiDAR data inside of the collected breaklines were then classified to Class 9
using TerraScan macro functionality. A buffer of 1 meter was also used around each hydro flattened
feature.
The breakline files were then translated to ESRI Shapefile format using ESRI conversion tools.
Data was then run through additional macros to ensure deliverable classification
levels matching LAS ASPRS Classification structure. GeoCue functionality was then
used to ensure correct LAS Version. In house software was used as a final
QA/QC check to provide LAS Analysis of the delivered tiles.

The NOAA Office for Coastal Management (OCM) received topographic files in LAS format. The files contained lidar
elevation and intensity measurements. The data were received in UTM Zone 16 (NAD83) coordinates
and were vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data were
meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid09.
2. The horizontal coordinate system was converted from UTM (meters) to Geographic (decimal degrees).

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)
