        abstract:  This data set contains lidar point data (Geodetic Coordinates) from a strip of Southern California coastline (including water, beach, cliffs, and top of cliffs) from Long Beach to the US/Mexico border. The data set was created by combining data collected using an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 in combination with geodetic quality Global Positioning System (GPS) airborne and ground-based receivers. The Bureau of Economic Geology, the University of Texas at Austin owns and operates an ALTM 1225 system (serial number 99d118). The system was installed in a twin engine Partenavia P-68 (tail number N3832K) owned and operated by Aspen Helicopter, Inc. The lidar data set described by this document was collected on 24 and 25 March 2006; Julian Days 08306 and 08406 (see Lineage, Source_Information, Source_Contribution for pass information). 99d118 instrument settings for these flights were; laser pulse rate: 25kHz, scanner rate: 26Hz, scan angle: +/- 20deg, beam divergence: narrow, altitude: 300-600m AGL, and ground speed: 95-120kts. Two GPS base stations were operating during each day of the survey, Point Loma and San Onofre on 08306 and Seal Beach and San Onofre on 08406 (see Lineage, Source_Information, and Source Contribution for coordinates). Data represented is all points including terrain, vegetation, and structures. This data also contains returns from the water surface. No processing has been done to remove returns from terrain, vegetation, structures or water surfaces.

        supplementalInformation:  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 20deg scan angle; and beam divergence: narrow = 0.2 milliradian (half angle, 1/e). The ALTM 1225 does not digitize and record the waveform of the laser reflection, but records the range and backscatter intensity of the first and last laser reflection using a 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. Wehr, A. and U.

            evaluationMethodDescription:  The lidar data is estimated to have a horizontal error of less than or equal to 0.50 m from comparison between kinematic GPS road survey and a 1m resolution grey-scale image generated from the lidar backscatter intensity data. Kinematic GPS data were superimposed on the lidar backscatter image and examined for any mismatch between the horizontal position of the ground GPS and the corresponding features on the lidar image. Horizontal agreement between the ground kinematic GPS and the lidar was within the resolution of the 1m -resolution backscatter image.

            evaluationMethodDescription:  The March 2006 lidar data were compared to the 1998 ATM LIDAR data to determine offsets in the vertical position. The ATM survey points are estimated to have a vertical accuracy of +/- 15 cm. The March 2006 lidar data set was sorted to find data points that fell within 0.5 m of an ATM LIDAR survey point along piers in the survey area. The mean elevation difference between the The elevation differences between the March 2006 survey and the ATM survey were used to estimate and remove TIM1 and TIM2 elevation biases from each lidar flight. The standard deviation of these elevation differences provides estimates of the lidar precision. After bias adjustment the mean lidar elevations have a vertical accuracy of 0.10 m.

                description:  GPS and XYZ-Point Data Processing Transfer raw ALTM 1225 flight data (laser ranges with associated scan angle information and IMU data), airborne GPS data collected at 1 Hz using Ashtech receiver, and ground-based GPS data collected at 1 Hz using Ashtech Z-12 receivers to processing computer. Generate decimated lidar point file from above three data sets using Optech's Realm 2.27 software. This is a 9-column ASCII data set with the following format: time tag; first pulse Easting, Northing, HAE; last pulse Easting, Northing, HAE; first pulse intensity; and last pulse intensity. View decimated lidar point file to check data coverage (i.e. sufficient overlap of flight lines and point spacing). Compute base station coordinates using National Geodetic Survey's PAGES-NT software. Compute aircraft trajectories from each base station GPS dataset using National Geodetic Survey's KINPOS software. Solutions for base stations coordinates and aircraft trajectories are in the International Terrestrial Reference Frame of 2000 (ITRF2000). A final aircraft trajectory was computed from a weighted average of the trajectories from the two base stations. Epoch-by-epoch weighting for the individual trajectories was inversely proportional to the baseline length (distance from base station) and solution RMS. Transformed trajectory solution from ITRF2000 to North American Datum of 1983 (NAD83) using the National Geodetic Survey's Horizontal Time Dependent Positioning software (http://www.ngs.noaa.gov/TOOLS/Htdp/Htdp.html). Input NAD83 trajectories and aircraft inertial measurement unit data into Applanix's POSProc version 2.1.4 to compute an optimal 50Hz inertial navigation solution (INS) and smoothed best estimate of trajectory (SBET). Substitute the INS and SBET into Realm 2.27. Generate a set of initial lidar instrument calibration parameters (pitch, roll, scale, and elevation bias) for each lidar flight, then incrementally improve parameters by iteratively comparing a subset of the lidar output to the GPS kinematic ground control. Once the instrument calibration parameters are sufficiently accurate, create the complete lidar point file (9-column ASCII file) for the entire survey area in UTM Zone 11 with elevations being heights above the GRS-80 reference ellipsoid (HAE). The output format from REALM 2.27 was a 9-column ASCII file containing: the second in the GPS week, easting, northing and HAE of the first lidar return, the easting, northing and HAE of the last lidar return, and the laser backscatter intensity of the first and last returns. Using the GEOID99 geoid model, heights above the GRS80 ellipsoid were converted to orthometric heights with respect to the North American Vertical Datum of 1988 (NAVD88). Parse the 9-column lidar point file into 3.75-minute quarter-quadrangle components. Convert UTM Easting and Northing to geodetic latitude and longitude with respect to the GRS80 ellipsoid. The conversion was computed using the TMGEOD and TCONPC fortran subroutines written by T. Vincenty (NGS). Each record contains 9 columns of data: time tag (seconds in the GPS week), first return Latitude,first return Longitude, first return NAVD88, last return Latitude, last return Longitude, last return NAVD88, first return intensity, and last return intensity. In some cases either the first or last return values may be missing (5 columns). Latitude and longitude are in decimal degrees with nine significant digits to retain the 0.01m resolution of the UTM coordinates. West longitude is negative and north latitude is positive. The UTM quarter-quad files were re-organized into latitude delineated files. UTM quarter-quads files that were delineated by the same upper and lower latitude bounds were concatenated. The lat-long files were named by the month-year of the survey (e.g. mar06) and the lower latitude bounding the quarter-quad. Processing occurred 20060324-20060726.

                description:   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) Processing notes:
