| * » Abstract |
LiDAR collected for the upper portion of the Flint River in central georgia. 237.6 sqmiles collected between May 1st and May 4th, 2009. The data contains 1 meter spaced pointscontaining classifications of unclassified (1), ground (2), noise (7) and water (9).Nominal spacing of points at 0.58 meters. Original contact information: Contact Org: AeroMetric, Inc Phone: 920-457-3631 |
| * Purpose |
The purpose of this project was to produce highly detailed and accurate digitalelevation maps of a portion of the Potato Creek watershed in Georgia for use as amanagement tool and to make these data available to natural-resource managers andresearch scientists. |

| 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. |

| » 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. |

| » 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. |
