        abstract:  The Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted for the Post Hurricane Gustav and Post Hurricane Ike Aerial Survey 2009 projects. Hurricane Gustav made US landfall at Cocodrie, LA on September 1, 2008. Hurricane Ike made US landfall near Galveston, TX on September 13, 2008. This data was produced for the US Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). The LiDAR point cloud was flown at a density sufficient to support a maximum final post spacing of 1.5 points per meter. The data are classified according to ASPRS LAS specifications as: 1 (Unclassified), 2 (Ground), 3 (Low Vegetation) 4 (Medium Vegetation), 5 (High Vegetation), 6 (Building), 7 (Low Point (Noise)), and 9 (Water). 3001 International Inc. acquired the 290 flightlines between February 3, 2009 and April 23, 2009. The Post Hurricane Gustav and Post Hurricane Ike Aerial Surveys 2009 were collected under the guidance of a Professional Mapper/Surveyor. Original contact information: Contact Org: 3001 International Inc. Title: LiDAR Department Phone: (985) 661 - 3001 Email: lidar@3001inc.com In addition to the lidar point data, topobathy bare earth Digital Elevation Models (DEMs) at a 1 meter grid spacing, created from the lidar point data are also available from the NOAA Digital Coast. The link to this data is provided in the URL section of this metadata record. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
        purpose:  The Post Hurricane Gustav and Post Hurricane Ike Aerial Survey 2009 projects will support the US Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) collection of data representing the post-hurricane condition of the beaches, barrier islands, and lakeshores along the coasts of Alabama, Louisiana, Mississippi, and Texas following Hurricanes Gustav and Ike.

            result: (missing)
        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy
            evaluationMethodDescription:  The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison of ground control points (GCP) and filtered LiDAR data points. Filtered LiDAR data has had vegetation and cultural features removed and by analysis represents bare-earth elevations. The RMSE figure was used to compute the vertical National Standard for Spatial Data Accuracy (NSSDA). Ground control was established by 3001, Inc. A spatial proximity analysis was used to select edited LiDAR data points contiguous to the relevant GCPs. A search radius decision rule is applied with consideration of terrain complexity, cumulative error and adequate sample size. Cumulative error results from the errors inherent in the various sources of horizontal measurement. These sources include the airborne GPS, GCPs and the uncertainty of the accuracy of the LiDAR data points. This accuracy is achieved prior to the sub-sampling that occurs through integration with the inertial measurement unit (IMU) positions that are recorded. It is unclear at this time whether the initial accuracy is maintained. The horizontal accuracy of the GCPs is estimated to be in the range of approximately 1 to 1.6 inches. Finally, sample size was considered. The specification for the National Standard for Spatial Data Accuracy is a minimum of 20 points to conduct a statistically significant accuracy evaluation (Minnesota Planning, 1999, Positional Accuracy Handbook, Minnesota Planning Land Management Information Center, St. Paul, Minnesota., p.3). Most statistical texts indicate that a minimum of 30 sample points provide a reasonable Approximation of a normal distribution. The intent of the NSSDA is to reflect the geographic area of interest and the distribution of error in the data set (Federal Geographic Data Committee, 1998, Geospatial National Standard for Spatial Data Accuracy, Federal Geographic Data Committee Secretariat, Reston, Virginia, p.3-4). Additional steps were taken to ensure the vertical accuracy of the LiDAR data including: Step 1: Precision Bore sighting (Check Edge-matching); Step 2: Compare the LiDAR data to the Field Survey (Field survey is to FEMA specifications and more stringent internal specifications); Step 3: Automated Filtering; Step 4: Manual Editing (Quality Control) Step ; Quantitative Value: 0.15 meters, Test that produced the value: See entity and attribute information

                description:  The Airborne Global Position System (ABGPS), inertial measurement unit (IMU), and raw scans are collected during the LiDAR aerial survey. The ABGPS monitors the xyz position of the sensor and the IMU monitors the orientation of the aircraft. During the aerial survey laser pulses reflected from features on the surface and are detected by the receiver optics and collected by the data logger. GPS locations are based on data collected by receivers on the aircraft and base stations on the ground. The ground base stations are placed no more than 20 km radius from the flight survey area. The instruments used to collect this data were the Optech ALTM Gemini and the Airborne Global Positioning System.

                description:  The ABGPS, IMU, and raw scans are integrated using proprietary software developed by Optech and delivered with the Optech ALTM Gemini System. The resultant file is in a LAS binary file format. The LAS file version 1.1 format can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are referenced to the Geographic NAD83 horizontal datum and NAVD88 vertical datum.

                description:  The data is subjected to rigorous QA/QC according to the 3001 Inc. Quality Control Plan and procedures. Very briefly, a series of quantitative and visual procedures are employed to validate the accuracy and consistency of the data. Ground control is established by 3001, Inc. and GPS-derived ground control points (GCPs) points in various areas of dominant and prescribed land cover. These points are coded according to landcover, surface material and ground control suitability. A suitable number of points are selected for calculation of a statistically significant accuracy assessment as per the requirements of the National Standard for Spatial Data Accuracy. A spatial proximity analysis is used to select edited LiDAR data points within a specified distance of the relevant GCPs. A search radius decision rule is applied with consideration of terrain complexity, cumulative error and adequate sample size. Accuracy validation and evaluation is accomplished using proprietary software to apply relevant statistical routines for calculation of Root Mean Square Error (RMSE) and the National Standard for Spatial Data Accuracy (NSSDA) according to Federal Geographic Data Committee (FGDC) specifications.

                description:  The NOAA Office for Coastal Management (OCM) received classified data (ASPRS LAS classifications include: 1 (unclassified), 2 (ground), 3 (Low Vegetation), 4 (Medium Vegetation), 5 (High Vegetation), 6 (Building), 7 (Low Point, (Noise)), and 9 (water)) in las format. The files contained LiDAR intensity and elevation measurements. OCM performed the following processing on the data for data storage and Digital Coast provisioning purposes: 1. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03. 2. The LAS header fields were sorted by latitude and updated.

                description:  Time stamps for each point in the files were converted from GPS seconds of the week to adjusted GPS seconds. The dates in the file names were used to determine the correct GPS week for the conversion and software program las2las was used to make the changes.

                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:
