Technical Acquisition Parameters:
Utilizing Leica ALS50 II laser systems which can collect data at laser pulse rates up to 150 KHz, Photo Science flew the project
area at 5,000 feet AGL and utilized a 29 degree full-angle field of view. Flights were accomplished nominally at 115 knots
(ground speed) with a pulse rate of 73,500Hz (73.5 KHz), collecting four returns per pulse. The scan rate was be set at 42Hz.
These settings resulted in a swath of 2,586 feet with maximum along track and cross track spacing of 4.62 feet (1.41 meters).
Environmental Acquisition Conditions:
Leaf-Off, snow free, non-flood conditions, low tide.
Low tide: Acquisition was performed within a window of +/- 3 hours from mean low tide for the project area (flight windows that
occur twice a day, that are approximately six hours in length but could be longer depending on the lunar cycle). Low tide is defined
as when the height of tide is different from Mean Lower Low water by fifty percent (50%) of the tide range or less as predicted by
the National Oceanic and Atmospheric Administration (NOAA), National Oceanic Service (NOS) Center for Operational Oceanographic Product
and Services (http://www.co-ops.nos.noaa.gov/). All flight lines affected by tide stage were coordinated with predicted tides at
existing gauges at Cape May, Ship John Shoal, and Reedy Point.
Nominal Pulse density:
Average point density is 1.58 points per square meter.
Average point spacing is 0.8 meters, or 8 decimeters.
Calibration procedures:
Photo Science has created a significant boresight facility at the Frankfort, KY airport where the Lidar platforms are stationed
when not in service. Boresighting at this facility takes place with our Lidar sensors at numerous times throughout the year.
Additionally, a mini-calibration site was established at the Millville Municipal Airport at the project site. Additional calibration
flights were conducted over this site to ensure accurate determination of the calibration parameters throughout the times of acquisition.
GPS:
Acquisition for this project was broken into three sub areas with base stations from the NGS database selected near the center of
each acquisition area to serve as control for all lifts. Ground based GPS receivers were occupied at these stations during all aerial
collection. The published NGS positions of these base stations and raw GPS observation data were used in the kinematic GPS
post-processing of all lifts to provide positioning for the point clouds produced for this project.
Maximum and mean differential baseline lengths:
Nominal Maximum base line distance = 20 Miles
Mean base line distance = 11 Miles
Geoid Model Used:
Geoid 03 was used for all elevation conversions to orthometric heights.
Data Collection Reference System:
Horizontal: New Jersey State Plane Coordinate System, 1983 North American Datum, feet
Elevation in North American Vertical Datum of 1988 (NAVD88), meters

Accuracy
The following aspects of the LiDAR data was verified during the course of the project processing:
-Data accuracy and errors
-Anomaly checks through full-feature hillshades and 3-D modeling
-Post automated classification Bare-earth verification
-Final quality control of deliverable products ensuring integrity, graphical quality
Horizontal Positional Accuracy
Compiled to meet 1 m horizontal accuracy
Vertical Positional Accuracy
Independent accuracy testing was performed by Dewberry using 60 high accuracy quality control checkpoints distributed
around Salem, Cumberland, and Cape May County on near level open bare terrain, urban terrain and near level vegetated terrain.
Dewberry uses testing procedures consistent with those specified in the National Standard for Spatial Data Accuracy (NSSDA).
Target equivalent to 2 ft contours: 0.363 m.
FVA - Fundamental Vertical Accuracy in open terrain (RMSEz x 1.9600): 0.13 m;
CVA - Consolidated Vertical Accuracy (95th Percentile) all categories: 0.16 m;
SVA - Supplemental Vertical Accuracy (95th Percentile) in mixed vegetation: 0.18 m;
SVA - Supplemental Vertical Accuracy (95th Percentile) in Urban: 0.12 m;
16 points were included inside the Cape May dataset, the consolidated accuracy (95th Percentile all categories) for these points
is 0.16 m.
; Quantitative Value: 0.13 meters, Test that produced the value:
Using NSSDA standards, this LiDAR dataset
was tested 0.13 m fundamental vertical accuracy at 95% confidence level in open terrain using RMSEz x 1.9600, compared to 0.363 m
for 2 ft equivalent contour.
Completeness Report
Data completeness and integrity was verified.
Conceptual Consistency
All LAS formatted LiDAR data are validated to ensure that data on delivery media is in correct physical format and is readable
and correctly georeferenced and projected. Note that LiDAR intensity is not calibrated or normalized.
Leica software was used in the post processing of the airborne GPS and inertial data that is critical to the positioning of the
sensor during all flights. This software suite includes Applanix's PosPac and Waypoint's GrafNav solutions. PosPac provides the
smoothed best estimate of trajectory (SBET) that is necessary for Leica'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 Leica 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 were removed using functionality provided by TerraScan and TerraModeler.
The project was tiled adhering to the State of New Jersey 5000'x5000' tile schema and each tile was saved in LAS format 1.1
including GPS time.
Note: The Julian date and year written in the LAS header is actually the file creation date and has no connection to the
acquisition date. However the GPS time (second of the week) is registered for each point in the LAS file and the week of
acquisition can be deduced from the file name which include the GPS week (1474 = week starting 04/06/2008; 1475 = week
starting 04/13/2008). When an area includes data from flightlines acquired over two different GPS weeks, separate files for the
data captured in each of the weeks are delivered. For example tile B18D14 has data from both weeks; therefore there are two
separate files: B18D14_1474.LAS & B18D14_1475.LAS.

A Terrascan macro was used to classify the Lidar points inside rivers and lakes from class 2 to class 9. This classification was
visually inspected by comparing the bare earth class against the hydro breaklines. Then the elevations were converted from feet
to meters to meet the final delivery specifications.
2008-07-01T00:00:00
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 Digital Coast:
1. The data were converted from New Jersey State Plane coordinates to geographic coordinates.
2. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03.
3. The LAS header fields were sorted by latitude and updated.
