Data Quality
Accuracy: |
none |
---|---|
Horizontal Positional Accuracy: |
Based on relative spacing to control points.; Quantitative Value: 1.0 meters, Test that produced the value: Data tested to meet accuracy. |
Vertical Positional Accuracy: |
The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison of ground control points (GCP) and filtered LiDAR data points.; Quantitative Value: 0.08 meters, Test that produced the value: 8.66 cm calculated vertical accuracy. This value iscomputed by comparing ground control elevation to the classified LiDAR ground surface andrepresents the RMSE of residuals on controls within the project area. |
Completeness Report: |
The LAS files were flown at a density sufficient to support a maximum final post spacing of 1 meter for unobscured areas. |
Conceptual Consistency: |
The LAS files were flown at a density sufficient to support a maximum final post spacing of 1 meter for unobscured areas. |

Process Steps
Process Step 1
Description: |
1m hydro enforced Arc ASCII Grids were loaded into Global Mapper catalog for review. Upon review itwas found that 15 original grids had excess tinning during processing and data was lost. Those 15 gridswere replaced by Aero-Metric.The replaced grids also had voids and lines across tiles, requiring repair. Repairs were made at NGTOCusing the original .las files to correct the residual line and void problems. Elevations were then checkedthrougout project with DRGs and were found to be accurate. There are no other areas of concern.Grid files were exported to 1m Image files for delivery to the NED. Each final image tile is 8994x x 6518yand is 223.7 mb in size. Shapefile of the extent of Potato Creek has been provided. Final data appears tobe very good. |

Process Step 2
Description: |
The NOAA Office for Coastal Management (OCM) received the files in las format with only a qualityassurance report, no metadata accompanied the data. The files contained lidar elevation and intensitymeasurements. The data were in GA State Plane coordinates and NAVD88 (orthometric) heights in feet.OCM performed the following processing for data storage and Digital Coast provisioning purposes:1. The data were converted from GA State Plane coordinates to geographic coordinates.3. The data were converted from NAVD88 (orthometric) heights in feet to GRS80 (ellipsoid) heights in meters using Geoid 03.4. Attempts were made to find the water class (9) though data received had water reclassed tounclassed along with a number of ground points, therefore processing to pull out only water classes were thwarted. |
