        abstract:  The South New Jersey County Lidar project is to provide LiDAR data for the New Jersey Department of Environmental Protection (NJ-DEP) for Cape May, Cumberland, and part of Salem Counties in New Jersey. These datasets will be the initial acquisition to support the United States Geological Survey (USGS) and the New Jersey Department of Environmental Protection (NJ-DEP). This LiDAR data set was collected in April 2008 for Cape May County and covers 285 square miles. The data are classified as follows: Class 1 - Unclassified/Extracted Features Class 2 - Bare Earth, Ground Class 9 - Water Class 12 - Overlap
        purpose:  The South New Jersey 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 2.0-meter Digital Elevation Models (DEMs) in ArcGrid format for approximately 874 square miles covering the 3 New Jersey counties of Cape May, Cumberland, and part of Salem that is south and west of the Coastal Area Facility Review Act (CAFRA) line.
        credit:  Acknowledgment of the U.S. Geological Survey would be appreciated for products derived from these data.

        supplementalInformation:  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. Data delivered from vendor as LiDAR point data in LAS 1.1; ASPRS classification scheme: Class 1 - Unclassified; Class 2 - Bare Earth Ground; Class 9 - Water; Class 12 - Overlap.

                description:  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.

                description:  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.

                description:  The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
