The lidar data was collected June 5-7, 2005. This data set seems to contain only model keypoints (points that are a thinned data set that is intended to remove extraneous data such as trees and points that are deemed redundant to the final bare earth product) that are classified as ground points. As a result, there are a lower number of points than in a full mass point lidar data set; and it is recommended that the data be downloaded as points and used with a TIN (Triangulated Irregular Network) or similar algorithm to produce a bare earth surface.

Due to the coarse nature of the LiDAR data no comparisons could be made between the intensity returns and the horizontal positions of field surveyed points. Project planning for high resolution LiDAR data and proven system performance were used to determine the expected horizontal accuracy. Final map data are referenced to the Florida High Accuracy Reference Network (HARN) adjustment for the North American Datum of 1983. Projection was Universal Transverse Mercator (UTM), Zone 17, units were meters. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: The LiDAR data was tested for a fundamental vertical accuracy and a supplemental vertical accuracy. The fundamental accuracy was tested for points that fall in open areas, not obscured by vegetation, having a normalized distribution. The supplemental accuracy was tested for points that fall in areas of vegetation, where data does not follow a normalized distribution. The fundamental vertical accuracy was tested 0.56-foot vertical accuracy at 95 percent confidence level using RMSE procedures with no outliers. The vertical root mean square error (RMSEz) was tested at 0.29-foot. The fundamental vertical accuracy meets the National Standards for Spatial Data Accuracy (NSSDA) for one-foot contours. These results were determined by comparing thirty-nine (39) field surveyed points obtained on hard surface and open areas with the Bald Earth Last Return LiDAR data. Refer to file 05680_fundamental_vert_acc.xls to view the results including summary statistics, normalized distribution, and a histogram. The supplemental vertical accuracy was tested 1.29-feet vertical accuracy at 95 percent confidence level, determined by the 95th percentile method. Point M3 having a -1.94 feet difference was determined to be an outlier. These results were determined by comparing forty (40) field-surveyed points obtained in brush and forested areas with the Bald Earth Last Return LiDAR data. Refer to file 05680_supplemental_vert_acc.xls to view the results including summary statistics, normalized distribution, and a histogram. Another analysis of the data will be made after the manual edit of the LiDAR data that may change these results. Ground control surveys were conducted under the supervision of a licensed Florida Surveyor and Mapper in accordance with Florida State Statutes. Horizontal values were referenced to the Florida High Accuracy Reference Network (HARN) adjustment for the North American Datum of 1983. Projection was Universal Transverse Mercator (UTM), Zone 17, units were meters. Vertical values were referenced to North American Vertical Datum of 1988 (NAVD88) units were feet. GPS and conventional survey methodology was used to generate the values of the surveyed points located throughout the project area. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: Not provided result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Not provided result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: LiDAR Data Acquisition -- The Lidar data was collected utilizing an Optech ALTM (Airborne Laser Terrain Mapper) 2025 in a Cessna 208 Grand Caravan aircraft on June 5, 2005 between 0930 and 1150 hours at an altitude of 3000' AGL. Data was also collected starting June 6, 2005 at 1830 hours and ending on June 7 at 0900 hours. The configuration used a scan half-angle of +/-17 degrees, a laser pulse repetition frequency of 25 kilohertz, and a flying speed of approximately 80 knots. Airborne GPS using a Novatel dual frequency GPS receiver was accomplished during the flight session to provide positional information for the Lidar platform. Simultaneous acquisition of ground base station data was performed using a Novatel and Leica SR9500 dual frequency receivers for the June 5, 2005 session. Two Leica SR9500 dual frequency GPS receivers were used for the second session on June 6-7, 2005. Each station remained in operation for the duration of the project flight. The ground base stations were set up over National Geodetic Survey (NGS) monuments AK0205 (Designation Number I4 71 A14) and AK7045 (Designation Number GIS 0472 CAS 1). Positional information on these monuments was obtained from Data Sheets retrieved from the NGS website (http://www.ngs.noaa.gov). The GPS data from the ground base stations and the airborne platform were processed together using Applanix POSPac 4.2 software module POSGPS. All adjustments were referenced to WGS84. The Inertial Measurement Unit (IMU) solution was accomplished to provide information regarding the attitude of the Lidar platform using the Applanix POSPac 4.2 software module POSProc. This solution was integrated with the Airborne GPS and adjusted using a Kalman filter in a forward/reverse solution to provide a Smoothed Best Estimate of Trajectory (SBET). Laser ranging from the airborne platform was accomplished using Realm 3.2 processing software to provide XYZ ground positions for each point. The final horizontal values were output in Universal Transverse Mercator (UTM), Zone 17, units are meters. The horizontal datum conforms to the current Florida High Accuracy Reference Network (HARN) adjustment for the North American Datum of 1983. The Vertical Datum is the North American Vertical Datum of 1988 (NAVD88), units are feet. dateTime: DateTime: 2005-06-07T00:00:00 processStep: (LI_ProcessStep) description: Classification of the laser data to extract above ground features such as buildings and vegetation leaving only bare earth ground points was performed using Terrasolid Ltd. Terrascan software (Version 003.003). The data was separated into five (5) separate sets 502 files representing Bald Earth First Pulse, Bald Earth Last Pulse, Extracted Features First Pulse, Extracted Features Last Pulse, and LAS format. The Bald Earth Last Pulse best represents the natural ground and is the file upon which all accuracy statements are based. The Extracted Features First Pulse best represents the canopy data that includes all features determined to be above the natural ground. dateTime: DateTime: 2005-07-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received the bare earth files in ASCII format. The data were Universal Transverse Mercator (UTM), Zone 17, units in meters, NAVD88 vertical datum and the vertical units of measure were feet. OCM performed the following processing to the ASCII data to make it available within Digital Coast: 1. The data were converted from UTM coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated. dateTime: DateTime: 2008-11-14T00:00:00 processStep: (LI_ProcessStep) 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: dateTime: DateTime: 2023-07-01T05:33:26 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
