When compared to GPS survey grade points in generally flat non-vegetated areas, at least 95% of the positions have an error less than or equal to 36.3 cm (equivalent to root mean square error of 18.5 cm if errors were normally distributed). result: report: (DQ_CompletenessCommission) evaluationMethodDescription: 1. EarthData's proprietary software, Checkedb, for verification against ground survey points. 2. Terrascan, for verification of automated and manual editing and final QC of products. result: report: (DQ_ConceptualConsistency) measureDescription: Compliance with the accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of lidar data. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical boresight adjustment. 2. The DTM (Digital Terrain Model) data were checked against the project control. 3. Lidar elevation data was validated through an inspection of edge matching and visual inspection for quality (artifact removal). result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: EarthData has developed a unique method for processing lidar data to identify and remove elevation points falling on vegetation, buildings, and other aboveground structures. The algorithms for filtering data were utilized within EarthData's proprietary software and commercial software written by TerraSolid. This software suite of tools provides efficient processing for small to large-scale, projects and has been incorporated into ISO 9001compliant production work flows. The following is a step-by-step breakdown of the process. 1. Using the lidar data set provided by EarthData, the technician performs calibrations on the data set. 2. Using the lidar data set provided by EarthData, the technician performed a visual inspection of the data to verify that the flight lines overlap correctly. The technician also verified that there were no voids, and that the data covered the project limits. The technician then selected a series of areas from the data set and inspected them where adjacent flight lines overlapped. These overlapping areas were merged and a process which utilizes 3-D Analyst and EarthData's proprietary software was run to detect and color code the differences in these plots and located the areas that contained systematic errors or distortions that were introduced by the lidar sensor. 3. Systematic distortions highlighted in step 2 were removed and the data was re-inspected. Corrections and adjustments can involve the application of angular deflection or compensation for curvature of the ground surface that can be introduced by crossing from one type of land cover to another. 4. The lidar data for each flight line was trimmed in batch for the removal of the overlap areas between flight lines. The data was checked against a control network to ensure that vertical requirements were maintained. Conversion to the client-specified datum and projections were then completed. The lidar flight line data sets were then segmented into adjoining tiles for batch processing and data management. 5. The initial batch-processing run removed 95% of points falling on vegetation. The algorithm also removed the points that fell on the edge of hard features such as structures, elevated roadways and bridges. 6. The operator interactively processed the data using lidar editing tools. During this final phase the operator generated a TIN based on a desired thematic layers to evaluate the automated classification performed in step 5. This allowed the operator to quickly re-classify points from one layer to another and recreate the TIN surface to see the effects of edits. Geo-referenced images were toggled on or off to aid the operator in identifying problem areas. The data was also examined with an automated profiling tool to aid the operator in the reclassification. 6. The final DEM was written to an ESRI grid format (.flt). 7. The point cloud data were also delivered in LAS format. 8. Project data was clipped to a 500-meter buffer outside of the official project boundary. dateTime: DateTime: 2005-07-28T00:00:00 processor: (CI_ResponsibleParty) individualName: Harold Rempel organisationName: EarthData International positionName: Senior Project Manager contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 301-948-8550 address: (CI_Address) deliveryPoint: 7320 Executive Way city: Frederick administrativeArea: Maryland postalCode: 21704 electronicMailAddress: metadata@earthdata.com role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The NOAA Coastal Services Center (CSC) received LAS files containing the bared-earth elevation and intensity data from URS.

The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights. dateTime: DateTime: 2006-01-03T00:00:00 processor: (CI_ResponsibleParty) individualName: Pamela Grothe organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) contactInstructions: Contact Data Center role: (CI_RoleCode) processor source: (LI_Source) description: Source Contribution: Ground Control.

EarthData Aviation., was contracted by EarthData International to collect ALS-40 Lidar data over Harrison County, Mississippi. The project site was flown on March 8th and 9th 2004 using a Horizons, Inc. aircraft with tail number N97HC. Lidar data was captured using an ALS-40 Lidar system, including an inertial measuring unit (IMU) and a dual frequency GPS receiver. Lidar was obtained at an altitude of 11,100 feet above mean terrain, at an average airspeed of 120 knots. Sensor pulse rate was set at 20 kHz with a field of view of 45 degrees and a rate of 11.0 Hz. Average swath width of the collected raw lines is 9,112.7 feet. Point spacing was 5 meters. Lidar data was recorded in conjunction with airborne GPS and IMU; the stationary GPS receiver was positioned over a control point located at the Gulfport airport. Recorded digital data was shipped via external hard drive to the production facility for processing. During airborne data collection, an additional 46 GPS control points were established throughout the airport. During the data acquisition, the receivers collected phase data at an epoch rate of 1 Hz. All GPS phase data was post processed with continuous kinematic survey techniques using "On the Fly" (OTF) integer ambiguity resolution. The GPS data was processed with forward and reverse processing algorithms. The results from each process, using the data collected at the airport, were combined to yield a single fixed integer phase differential solution of the aircraft trajectory.
