        abstract:  This lidar point data set was collected during low tide conditions along an approximately 500-700 meter wide strip of the Southern California coastline within an area extending south from Long Beach to the US/Mexico border. Data were collected in Los Angeles, Orange and San Diego counties from south of the Downtown Long Beach Marina in Long Beach, California to north of Oceanside on March 28, 2007 between 18:54 and 22:01 UTC. Data were collected in Orange and San Diego counties from south of Dana Point to south of the United States-Mexico border near Playas de Tijuana, Baja California, Mexico on March 29, 2007 between 19:08 and 22:00 UTC. Data set features include water, beach, cliffs, and top of cliffs. The all points data set contains the complete point cloud of first and last return elevation and laser intensity measurements recorded during the spring 2007 airborne lidar survey conducted semi-annually by the University of Texas at Austin for the Southern California Beach Processes Study. The data set was generated by the processing of laser range, scan angle, and aircraft attitude data collected using an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 system and geodetic quality Global Positioning System (GPS) airborne and ground-based receivers. Instrument settings and parameters during survey were: Nominal on-ground beam diameter: 25 cm Pulse rate: 25 kHz Maximum number of returns recorded: 2 Minimum separation between detected returns from a single pulse: 4.3 m Laser wavelength: 1064 nm Frequency of GPS sampling: 1 Hz Frequency of IMU sampling: 50 Hz; Scan angle: +/- 20 degrees Nominal height of instrument above ground: 1100 m Nominal single-swath pulse density: 2 m Nominal aggregate pulse density: 0.75 Nature of vertical control: Kinematic and static GPS points
        purpose:  The data described in this document will be compared with previous and forthcoming data sets to determine rates of shoreline change along the Southern California coastline. The SCBPS program is designed to improve the understanding of beach sand transport by waves and currents, thus improving local and regional coastal management.

        supplementalInformation:  The University of Texas at Austin Center for Space Research operated an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 system installed in a single engine Cessna 206 to collect lidar data for the survey. Global Positioning System (GPS) data were collected simultaneously with three geodetic quality Ashtech Z-12 receivers installed in the aircraft and at two temporary base stations operated during the survey. An Inertial Measurement Unit (IMU) used three orthogonal accelerometers and gyroscopes to collect in-flight instrument orientation information. The Cessna 206 aircraft used in the survey is owned and operated by the Texas Department of Transportation. The ALTM 1225 (SN#99d118) lidar instrument has the following specifications: operating altitude = 410-2,000 m AGL; maximum laser pulse rate = 25 kHz; laser scan angle = variable from 0 to +/-20deg from nadir; scanning frequency = variable, 28 Hz at the 20 deg scan angle; and beam divergence: narrow = 0.2 milliradian (half angle, 1/e). The ALTM 1225 records the range and backscatter intensity of the first and last laser reflection using an Avalanche Photo diode constant-fraction discriminator and two Timing Interval Meters (TIM). ALTM elevation points are computed using three sets of data: laser ranges and their associated scan angles, platform position and orientation information, and calibration data and mounting parameters (Wehr and Lohr, 1999). Global Positioning System (GPS) receivers in the aircraft and on the ground provide platform positioning. The GPS receivers record pseudo-range and phase information for post-processing. Platform orientation information comes from an Inertial Measurement Unit (IMU) containing three orthogonal accelerometers and gyroscopes. An aided-Inertial Navigation System (INS) solution for the aircraft's attitude is estimated from the IMU output and the GPS information.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Horizontal Positional Accuracy Report
            evaluationMethodDescription:  Maximum allowable PDOP using a 15 degree elevation mask during data collection was 3.5. The lidar data is estimated to have a horizontal error of less than or equal to 1.0 m. To assess horizontal accuracy, selected portions from each lidar data set (last return only) were used to generate a 1m x 1m digital elevation model (DEM). Data from ground surveys conducted using kinematic GPS techniques and estimated to have a horizontal accuracy of 0.01-0.03 m were superimposed on the lidar DEM and examined for any mismatch between the horizontal position of the ground GPS and the corresponding feature on the lidar DEM. Horizontal agreement between the ground kinematic GPS and the lidar was within the resolution of the 1m x 1m DEM.

            nameOfMeasure:  Vertical Positional Accuracy Report
            evaluationMethodDescription:  (North) The March 28, 2007, lidar data were compared to kinematic GPS ground survey points collected along an approximately 2 kilometer long stretch of the East Pacific Coast Highway near Laguna Beach. The March 28, 2007, lidar data set was sorted to find data points that fell within 1 m of the GPS points. (South) The March 29, 2007, lidar data were compared to 17 GPS ground survey points collected throughout a parking lot adjacent to the North Torrey Pines Road. The March 29, 2007, lidar data set was sorted to find data points that fell within 2 m of the GPS points. For each survey area (north and south), the mean elevation difference between the selected lidar points and their respective GPS points was used to estimate and remove elevation bias from the lidar. The standard deviation of the elevation differences provided estimates of the lidar precision. The bias was removed so that mean lidar elevations have a vertical accuracy of 0.10 m RMSE.

                description:  Raw GPS data were downloaded from three Ashtech Z-12 GPS receivers. One receiver collected in-flight aircraft data; the other two collected data during flight time at separate base stations. The GPS data were converted into RINEX2 format with pseudorange smoothing applied. The National Geodetic Survey's PAGES-NT software was used to compute double differenced, ionospherically corrected, static GPS solutions for each GPS base station with precise ephemerides from the International GPS Service (IGS) with respect to selected CORS sites. As part of the solution tropospheric zenith delays were estimated and L1 and L2 phase biases were fixed as integers. Aircraft trajectories were estimated with respect to all base stations using National Geodetic Survey's Kinematic and Rapid-Static Software (KARS) software. Trajectories were double-differenced, ionospherically corrected, bias-fixed GPS solutions computed with precise IGS ephemerides. Coordinates for base stations and trajectories were in the International Terrestrial Reference Frame of 2000 (ITRF00). Aircraft trajectories were transformed from the ITRF00 to North American Datum of 1983 (NAD83) using the Horizontal Time Dependent Positioning (HDTP) software (Snay, 1999).

                description:  The SBET, laser range observations, scanner position information, and GPS/internal clock files were processed in the Realm 2.27 software suite to generate uncalibrated lidar data points in the Universal Transverse Mercator (UTM) projection. Lidar point data were compared to 1998 ATM LIDAR data over several cross-track piers and roads to estimate lidar instrument calibration parameters: roll and pitch biases, scanner scale factor, and first/last return elevation biases. An iterative, least-squares methodology was used to estimate calibration parameters so as to minimize differences between lidar and ground GPS data. Samples of lidar data were used to create high-resolution digital elevation models (DEM); these DEMs were inspected for horizontal or vertical anomalies. Data collected on March 28, 2007, were compared to kinematic GPS points collected along the E. Pacific Coast Hwy near Laguna Beach. Data collected on March 29, 2007, were compared to kinematic GPS points collected in a parking lot near North Torrey Pines Road. After system calibration and initial quality control step, the adjusted lidar x,y,z-point data were generated by REALM software and output using the UTM Zone 11 coordinate system with elevations being heights above the GRS-80 reference ellipsoid (HAE). The output format from REALM 2.27 is a headerless space-delimited 9-column ASCII file that contains: Column 1 = the point time tag in seconds in the GPS week; Columns 2-4 = the UTM Zone 11 North easting, UTM Zone 11 North northing and height above ellipsoid (HAE) of the first lidar return; Columns 5-7 = the UTM Zone 11 North easting, UTM Zone 11 North northing and HAE of the last lidar return; and Columns 8 & 9 = the laser backscatter intensity of the first and last returns.

                description:  Heights above the GRS80 ellipsoid (HAE) were converted to orthometric heights with respect to the North American Vertical Datum of 1988 (NAVD88), using the GEOID99 model. GPS time tags were used to separate the data collected on a single day into distinct passes. The resulting pass data sets were then parsed into 3.75-minute USGS quarter-quadrangle components containing the complete point cloud. Each output file includes data points found within a 20 meter buffer area surrounding each quarter quadrangle. Outlier data points that exceeded designated elevation thresholds (< -20 m or > 250 m) were eliminated during the parsing process.

                description:  The NOAA Coastal Services Center (CSC) received the lidar files in ASCII format. The files contained lidar intensity and elevation measurements. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. Data converted from UTM coordinates to geographic coordinates. 2. Data converted from NAVD88 heights to ellipsoid heights using GEOID99. 3. Data converted from dual return xyz format to xyz text format with return numbers to las format. 4. The LAS data were sorted by latitude and the headers were updated.

                description:  Source Contribution: GPS data. Two Ashtech Z-12 GPS receivers placed at precisely located base stations collected GPS data at 1 second intervals throughout the period of airborne lidar data collection. Data collection commenced prior to take off and ceased subsequent to touch down. A third Ashtech Z-12 GPS receiver collected in-flight GPS data at 1 second intervals. Data were downloaded and stored each day after flight completion. File names included standardized references to location and date. These data were used for ALTM range file processing.
