            evaluationMethodDescription:  Expected accuracies are not tested accuracies. OPTECH ALTM 3100 LiDAR Sensor - Expected horizontal accuracy of elevation products as determined from system studies and other methods is 1/2,000th of the flight height, which, in the instance of this particular project, was 3,280 U.S. survey feet (1,000 meters) AGL, giving a horizontal tolerance of less than 1.640 U.S. survey feet (0.500 meters). OPTECH ALTM 3100EA LiDAR Sensor - Expected horizontal accuracy of elevation products as determined from system studies and other methods is 1/5,500th of the flight height which, in the instance of this particular project, was 3,280 U.S. survey feet (1,000 meters) AGL, giving a horizontal tolerance of less than 0.596 U.S. survey feet (0.182 meters). OPTECH ALTM Gemini LiDAR Sensor - Expected horizontal accuracy of elevation products as determined from system studies and other methods is 1/11,000th of the flight height, which, in the instance of this particular project, was 5,905 U.S. survey feet (1,800 meters) AGL, giving a horizontal tolerance of less than 0.537 U.S. survey feet (0.164 meters). Horizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The standard system results for horizontal accuracy are less than 1 meter. Not tested therefore horizontal accuracy is assumed as 1.0 m. ; Quantitative Value: 1.0 meters, Test that produced the value: See LiDAR data report.

Six-hundred and seventy-nine (679) test points were collected throughout the project area in several vegetation categories. The RMSE calculations were performed on the bare-earth, orthometric surface and determined for each of the four LiDAR acquisition areas separately. ; Quantitative Value: 0.11 meters, Test that produced the value: The following statements are derived in accordance with the ASPRS Guidelines for Vertical Accuracy Reporting for LiDAR Data (Flood, M., 2004). Tested 0.365 U.S. survey feet (0.111 meters) fundamental vertical accuracy at the ninety-five percent confidence level in open terrain using RMSEz x 1.9600.

                description:  During acquisition, two base stations were used to support the precise positioning and orientation of the LiDAR sensor head. At times an additional base station set at the Oxford Airport was used as a back-up. The base stations were positioned so that the aircraft would be no further than 20-miles from a single base station at any time during the flight and were placed on the control points established by Maptech during the ground control phase of the project. The LiDAR acquisition commenced on December 17, 2009 and was completed on March 5, 2010. Initial processing of the LiDAR data determined that reflights were necessary; in part because of sensor or base station malfunctions. The reflights occurred between June 27, 2010 and July 9, 2010. To achieve better penetration of the vegetation during the reflights, two passes were conducted over the reflight area; one in each direction. Detailed flight information and flight logs can be found in the separate Flight Report submitted with the project.

                description:  For redundancy and accuracy purposes, the airborne GPS data were processed from two base stations using POSGPS from Applanix, Inc. The agreement between a minimum of two solutions checked or combined between a minimum of two stations was better than 10 cm in each of X, Y, and Z. These trajectories were used in the processing of the inertial data. The inertial data were processed using POSProc from Applanix, Inc. This software produces an SBET ("smooth best estimate of trajectory") using the GPS trajectory from POSGPS and the roll, pitch and heading information recorded by the POS (Position Orientation System). DASHMap uses the SBET to generate a set of data points for each laser return in the LAS file format. Each data point is assigned an echo value so it can be segregated based on the first and last pulse information. This project's data were processed in strip form, meaning each flight line was processed independently. Processing the lines individually provides the data analyst with the ability to QC the overlap between lines. Each strip was then imported into a project using TerraScan (Terrasolid, Ltd.) and the project management tool GeoCue (GeoCue Corp.). By creating a project the various flightlines are combined while breaking the dataset as a whole into manageable pieces. This process also converts the dataset from the geographic coordinate system (NAD83) to the State Plane Coordinate System (NAD83), Mississippi West, Feet, and utilizing standard ESRI transformations. The ellipsoid height values were converted to NAVD88, Feet, orthometric values using Geoid03, provided by NGS. Individual lines were then checked against adjacent lines and intersecting control lines to ensure a cohesive dataset. The data from each line were then combined and LiDAR intensity images were produced to visually check the horizontal positioning of the LiDAR data. Stereo pairs were generated from the LiDAR intensity data using Geocue and LiDAR1CuePac (Geocue Corp.). LiDARgrammetry was then utilized to collect breaklines where necessary along hydro features to support the contour generation. These breaklines were collected as a 3D element in the MicroStation (Bentley Systems, Inc.) environment utilizing ISSD (Z/I Imaging). A Triangular Irregular Network (TIN) was generated using the final surface data. Contours were then created from the TIN utilizing TerraModeler (Terrasolid, Ltd.).

                description:  The NOAA Office for Coastal Management (OCM) received topographic files in text format from the Mississippi Department of Environmental Quality (MDEQ). The files contained lidar easting, northing and elevation. The data were received in Mississippi State Plane West 2302, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical and horizontal units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The ASCII files were converted from txt format to las format using LASTools' txt2las 2. The LAS tiles were retiled to remove the buffer, then duplicate points were removed 3. The LAS tiles were then run through LASGround in order to extract surface classifications. 4. The las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03. 5. The las files' vertical units were converted from feet to meters, removing bad elevations. 6. The las files were converted from a Projected Coordinate System (MS SP West) to a Geographic Coordinate system (NAD83) 7. The las files' horizontal units were converted from feet to decimal degrees and converted to laz format.

                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:
