        abstract:  This metadata record describes the classified bare earth lidar data products derived from the Harford County, MD LiDAR project covering the defined project area of Harford County and immediate surroundings. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
        purpose:  To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and hydrologic modeling. LAS and bare earth DEM data products are suitable for 2 foot contour generation and orthorectification of aerial imagery collected in conjunction with the lidar data.

            evaluationMethodDescription:  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 meet or exceed the project specified 0.6 meter RMSE. Qualitative value: 0.6, Test that produced the valued: This value is computed by comparing ground control to an intensity based image derived from the classified LiDAR data and represents the RMSE of residuals on controls within the project area.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy
            evaluationMethodDescription:  Vertical accuracy requirements for the Harford County lidar project are defined as sufficient to support 2' contour or RMS = to 1/2 of the 2' contour interval (0.67') for well defined points. Vertical 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 lidar capture was composed of 3 separate flight missions on 2 separate dates . Lines 18-30 and lines 31-40 flown 20130309 and lines 1-17 flown 20130406. Each of the 3 flight missions was post processed and classified as separate blocks and then combined vertical accuracy statistics developed for the entire data set. The vertical accuracy of the bare earth lidar DEM, utilizing 22 well defined control points in the project area, was tested with a resultant RMSE of 0.223'.Qualitative value:0.223, Test that produced the value: Meeting the vertical accuracy requirement is ensured by comparing ground control elevation to the classified LiDAR ground surface. The project-wide RMSE is calculated from the vertical differences between surveyed ground control and the bare earth lidar surface and represents the RMSE on controls within the project area.
            result: (missing)
        report:  (DQ_CompletenessCommission)
            nameOfMeasure:  Completeness Report
            evaluationMethodDescription:  LiDAR data is collected for the project area. Post processing of the simultaneously acquired GPS/INS is performed and applied to the laser returns to output a point cloud in the specified project coordinate system and datums. The point cloud data is then subjected to automated classification routines to assign all points in the point cloud to ground, water, overlap and unclassified point classes. Anomalous laser returns that occur infrequently are removed entirely from the data set. The ground class points are then compared to surveyed ground control to develop an accuracy measure of the laser terrain data.

                description:  The georeferenced lidar data is then classified and edited in Terrasolid Terrascan software. Data is classified to produce: Class 1: unclassified points, Class 2: ground points, Class 7: low point, Class 17: overlap unclassified, Class 18: overlap bare-earth ground.

                description:  The ground class of the processed lidar data is then compared to the ground control and elevation differences between the lidar surface and surveyed elevation are recorded in tabular form. Vertical accuracy statistics are then developed to produce vertical RMSE and overall accuracy estimates and reports.

                description:  NOAA OCM downloaded the point cloud data from the Maryland iMAP (imap.maryland.gov). Data were in Maryland State Plane (1900) survey feet with vertical NAVD88 (Geoid03) survey feet. Data were reprojected to geographic coordinates and vertically transformed to ellipsoid heights in meters. It should be noted that Geoid03 is unusual for a data set collected in 2013. Since the metadata explicitly listed Geoid03, that model was used to transform the data. The LAZ files had no georeferencing headers and could not provide verification. Examination of the data showed only classes 1,2,7, and 12 were present in the data. This is contrary to the above processing step that does not mention class 12 and lists classes 17 and 18. Class 12 is believed to be overlap points that have not been otherwise classified. Data were ingested into the Digital Coast Data Access Viewer for custom download.

                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:
