The standard system results for horizontal accuracy meet or exceed the project specified 1.0 meter RMSE. This value is computed by comparing ground control to a DEM derived from the classified LiDAR data and represents the RMSE of residuals on controls within the project area. Vertical Positional Accuracy For the DEM data, the FVA, SVA, and CVA were computed. Vertical accuracy was tested with independent survey check points located in various terrain types within Berrien County. Check points were not used in the calibration or post processing of the point cloud data. Survey check points were distributed throughout the block area. Specifications for this project require that the FVA be 9.25 cm (18.13 cm or better @ 95 percent confidence level). The RMSE values are defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASRPS Guidelines. FVA 0.067m RMSE, or 0.131m FVA @ 95 percent Confidence Interval The FVA was tested using 38 independent survey check points located in flat terrain types within Area 5. The survey checkpoints were distributed throughout the block area. The 38 independent check points were surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. CVA 0.092m RMSE, or 0.192m CVA @ 95th Percentile using all FVA and SVA class checkpoints (CVA) The CVA was tested using 155 independent survey check points located in various terrain types within Area 5. The 155 independent check points contained all FVA and SVA class points and were surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. SVA 0.080m RMSE, or 0.159m SVA @ 95th Percentile The SVA for the Urban class was tested using 36 independent survey check points located in urban terrain types within Area 5. The 36 independent check points were surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. 0.108m RMSE, or 0.215m SVA @ 95th Percentile 0.116m RMSE, or 0.192m SVA @ 95th Percentile 0.098m RMSE, or 0.196m SVA @ 95th Percentile. The SVA for the Low Veg class was tested using 17 independent survey check points located in low vegetation terrain types within Area 5. The 17 independent check points were surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. 0.116m RMSE, or 0.192m SVA @ 95th Percentile SVA for Medium Veg class tested using 27 independent survey check points located in medium veg terrain types within Area 5. The 27 independent check points surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from DEM surface were then compared to the elevation values of the surveyed control. 0.098m RMSE, or 0.196m SVA @ 95th Percentile SVA for High Veg class tested using 37 independent survey check points located in high veg terrain types within Area 5. The 37 independent check points surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from DEM surface were compared to the elevation values of the surveyed control. Completeness Report 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. Once clean bare earth points are established, DEMs are created using bare earth points and hydro features. The DEM surface is then compared to the survey checkpoints. These accuracies must pass the Fundamental Vertical Accuracy, Supplemental Vertical Accuracy, and Consolidated Vertical Accuracy specifications. Conceptual Consistency LiDAR data is collected within the project area and processed. After the DEMs were created, the dataset was verified against control. Control was collected in 5 areas. Area 5 includes Allegan, Berrien, and Van Buren. Accuracy results are reported for Area 5. At selected locations throughout the site, accurate GPS coordinates and elevations are surveyed and the points are marked with targets. 2015-01-01T00:00:00 New LiDAR data is captured for the project area using a Leica ALS80 w/MPiA LiDAR instrument an integrated IPAS20 GPS/INS system mounted within a Aero Commander twin engine airplane. 2015-01-01T00:00:00 The airborne GPS data is post-processed in Intertial Explorer software and LEICA CloudPro software to determine the LiDAR sensor's angle and orientation in the terrain (project) coordinate system and datums during the survey. 2015-01-01T00:00:00 The post processed GPS/INS solution is applied to the raw lidar data to orient and project the data points into the project area reference system as an unclassified point cloud. 2015-01-01T00:00:00 The georeferenced lidar data is then classified and edited in Terrasolid Terrascan software. Data is classified to produce: Class 1: unclassified, Class 2: ground, Class 7: low point, Class 9: water, Class 10: ignored ground, Class 11: withheld. 2015-01-01T00:00:00 The bare earth points of the processed lidar data are then output to a DEM tile format. The DEM is compared to the ground control and elevation differences between the 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. 2015-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) downloaded 2740 MI_13Co-BerrienCO_2015 Digital Elevation Model (DEM) files from this USGS site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/OPR/.
