High accuracy LiDAR data covering Mercer County New Jersey (228 sq miles). These datasets will be the initial acquisition to support
general geospatial needs of the USGS and the New Jersey Department of Environmental Protection (NJ-DEP).
The purpose of the Mercer County Lidar project is to provide LiDAR data for New Jersey Department of Environmental Protection (NJ-DEP).
This project acquired and produced high accuracy bare-earth processed LiDAR data in LAS format and 1.0-meter Digital Elevation Models
(DEMs) in ArcGrid format for approximately 228 square miles of Mercer County.
Acknowledgment of the U.S. Geological Survey would be appreciated for products derived from these data.

- 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 7,000 feet AGL and utilized a 19 degree full-angle field of view. Flights were accomplished nominally at 98 knots
(ground speed) with a pulse rate of 113,600Hz, collecting four returns per pulse. The scan rate was be set at 50.4Hz. These
settings resulted in a swath of 2,343 feet with maximum along track and cross track spacing of 3.28 feet (1.0 meters).
- Environmental Acquisition Conditions: Leaf-Off, snow free, non-flood conditions.
- Nominal Pulse density:
Average point density is 3.15 points per sq. Meter
Average point spacing is 0.56 meters.
- 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 Robbinsville 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 completed using the base station from the NGS database selected near the center of the
acquisition area to serve as control for all lifts. A ground based GPS receiver was occupied at the station during all aerial
collection. The published NGS positions of the base station 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 was approximately 20 Miles
Mean base line distance was approximately 11 Miles
- Geoid Model Used:
Geoid 03 was used for all height conversion from ellipsoidal to orthometric heights.
- Reference System:
Horizontal: New Jersey State Plane Coordinate System, 1983 North American Datum, feet
Vertical: North American Vertical Datum of 1988 (NAVD88), feet

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 1m horizontal accuracy
Vertical Positional Accuracy
Using NSSDA standards, this LiDAR dataset will have a fundamental vertical accuracy of 35.32 cm at 95% confidence level, based on RMSE
of 18 cm in the open terrain land cover category.
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 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.

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.

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained Lidar elevation and intensity measurements.
The data were in projected in New Jersey State Plane (NAD83) coordinates, and referenced to the orthometric datum of NAVD88 utilizing
Geoid 03. OCM performed the following processing to the data to make it available within the Digital Coast:
1. The data were converted from New Jersey State Plane ned(NAD83) coordinates to geographic coordinates (NAD83).
2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03.
3. The LAS data were sorted by latitude and the headers were updated.
