Auto-filtering uses algorithms to reclassify data in the point cloud. Hand-filtering involves the use of a technician working in a graphic environment to reclassify the erroneous points that may remain in the LIDAR point cloud after auto filter. Horizontal Positional Accuracy Horizontal accuracy is verified in three tests. During boresighting, adjoining flightlines are view in profile and hard edged features are observed and if necessary the flightlines are adjusted for good relative horizontal and vertical fit. The second test for horizontal accuracy is by comparing raw contours from each flightline against adjoining flightlines at specific points. The final test is the vertical LIDAR control report. Vertical Positional Accuracy Survey control points were used to validate the accuracy of the LIDAR surface model after automatic and hand filtering. This surface exceeds the NDEP vertical accuracy specifications of 18.5cm RMSEz. The vertical accuracy for this data set is 0.60 ft (0.18 m) RMSEz. Completeness Measure Cloud Cover: 0 Completeness Report This dataset contains classified returns of the LIDAR sensor. The sensor data was verified in MARS software to ensure complete coverage. Conceptual Consistency Calibrations of the LIDAR flightline data are performed; this process is known as boresighting. The flightlines are compared to evaluate both their relative and absolute accuracies. LIDAR data was collected using Merrick's ALS60 sensor. The raw data was verified in MARS software for complete coverage of the project area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: error points, ground points, and canopy/building points. The data was next taken into a graphic environment to reclassify the erroneous points that may remain in the LIDAR point cloud after auto filter. 2007-06-11T00:00:00 The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity and elevation measurements. OCM performed the following processing on the data for data storage purposes and Digital Coast provisioning: 1. The data were converted from UTM, Zone 16 coordinates to geographic (NAD83) coordinates; 2. The data were filtered to remove elevation outliers; 3. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03; 4. The LAS header fields were sorted by latitude and updated; 2011-05-10T00:00:00 Source Contribution: GPS control network for LIDAR acquisition and processing. | Source Geospatial Form: spreadsheet | Type of Source Media: spreadsheet Ground Control 2010-01-01 publication 2007-11-12 Source Contribution: LIDAR points form the basis of the DTM surface. | Source Geospatial Form: LAS data | Type of Source Media: digital data LIDAR 2010-01-01 publication 2010-03-30 2010-04-01
