Data Quality
| Accuracy: |
The accuracy of this data set has not been tested. The accuracy of the methodology has been published in Irish, J.L., McClunk, J.K., Lillycrop, W.J., 2000. Airborne lidar bathymetry: the SHOALS system. PIANC Bulletin, No. 103-2000, 45-53. Vertical accuracy is believed to be on the order of 15 cm root mean square error. Horizontal accuracy is expected to be on a similar order. |
|---|---|
| Horizontal Positional Accuracy: |
The horizontal accuracy of this dataset was not tested. |
| Vertical Positional Accuracy: |
The vertical accuracy of this dataset was not tested. |
| Completeness Report: |
All elevation data points that appeared to be within a reasonable vertical range were retained, and other points were thrown away. This filtering process was performed manually. |
| Conceptual Consistency: |

Process Steps
Process Step 1
| Description: |
The NOAA Office for Coastal Management (OCM) received files in ascii format. The files contained LiDAR elevation measurements. The xy data in the files were in LA State Plane feet and elevations were in US feet. OCM performed the following processing on the data to make it available within the Digital Coast Data Access Viewer (DAV): 1. Each LiDAR xyz point within the ascii file was reprojected to geographic decimal degrees using GCTP and elevations were converted from U.S. survey feet to meters. The data were then converted to binary las files. Default values for which there is no corresponding input were assigned as follows for each las elevation data record: intensity = 0, retn = 1, nret = 1, class = 0. 2. The las files were sorted by latitude and the las header fields were updated. 3. Elevations converted to ellipsoid. |
