Abstract

This data set is the topographic elevation point data derived from multiple return light detection and ranging (LiDAR) measurements for seven

counties in Georgia. These counties are: Bibb, Harris, Heard, Jasper, Jones, Monroe, and Walton. The Statement of Work (SOW) was developed

by the National Oceanic and Atmospheric Administration's (NOAA) Office for Coastal Management (referred to as the Center) in partnership

with the Georgia Department of Natural Resources (GADNR) Environmental Protection Division (EPD). The data included hydro flattened DEMs for

inclusion into the National Elevation Dataset (NED).

LiDAR was collected as weather permitted between March 2 and April 14, 2011. In all, a total of 2570 square miles were collected in 390

flightlines. The data were collected at 1.0 point per square meter (1.0 m GSD) for the seven "inland" counties in Georgia. This area was

flown during snow free and leaf-off conditions.

The data contains las points with the following classifications:

Class -1 No Classification

Class 2 Ground

Class 7 Low Point (Noise)

Class 9 Water

Class 10 Land below sea level

Class 12 Overlap

Data Quality

Accuracy:

The project area requires LiDAR to be collected on average of 1.0 meter point spacing or better and vertical accuracy of 18.0 centimeters RMSE

or better to support 2' contour generation when combined with breaklines.
Vertical Positional Accuracy:

Deliverables were tested by Photo Science, Inc. for both vertical and horizontal accuracy. All data are seamless from one tile to the next,

no gaps, or no data areas. The vertical unit of the data file is in survey feet with 2-decimal point precision. The vertical accuracies for this

data set are different for each county.

For Bibb, Jasper, Jones, and Monroe counties: vertical accuracy is 7.07 cm RMSE

For Harris County: vertical accuracy is 9.9 cm RMSE

For Heard County: vertical accuracy is 13.3 cm RMSE

For Walton County: vertical accuracy is 6.6 cm RMSE
Completeness Report:

Process Steps

Process Step 1

CC ID: 1132947
Description:

Applanix software was used in the post processing of the airborne GPS and inertial data that is critical to the positioning

and orientation of the sensor during all flights. POSPac MMS provides the smoothed best estimate of trajectory (SBET) that is necessary

for Optech's post processor to develop the point cloud from the LiDAR missions. The point cloud is the mathematical three dimensional

collection of all returns from all laser pulses as determined from the aerial mission. At this point this data is ready for analysis,

classification, and filtering to generate a bare earth surface modelin which the above ground features are removed from the data set.

The point cloud was manipulated within the Optech or Leica software; GeoCue, TerraScan, and TerraModeler software was used for the automated

data classification, manual cleanup, and bare earth generation from this data. Project specific macros were used to classify the ground

and to remove the side overlap between parallel flight lines.

All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler.

Class 2 LIDAR was used to create a bare earth surface model. The surface model was then used to heads-up digitize 2D breaklines of

inland streams and rivers. Inland Ponds and Lakes of 0.5 acres or greater were also collected along with the Coastal

Shoreline for the ten "coastal" counties and 2.0 acres for the seven "inland" counties.

Elevation values were assigned to all Inland Ponds, Lakes, and Shorelines using TerraModeler functionality.

Elevation values were assigned to all Inland streams and rivers using Photo Science proprietary software.

All Class 2 LIDAR data falling inside of the collected breaklines were then classified to Class 9 and Class 2 LIDAR data falling within a

proximity of three feet will be classified to Class 10 using TerraScan macro functionality.

The breakline files were translated to ESRI Shapefile format using ESRI conversion tools.

Data was then run through additional macros to ensure deliverable classification levels matching LAS ASPRS Classification structure. GeoCue

functionality was used to ensure correct LAS Version. In house software was used as a final QA/QC check to provide LAS Analysis of the delivered tiles.

Tiles were run through automated scripting within ArcMap and were combined with the Hydro Flattened Breaklines to create the 4' DEM. Final

DEM tiles were clipped to the tile boundary in order to provide a seamless dataset.

A manual QA review of the tiles was completed in ArcMap and Global Mapper to ensure full coverage with no gaps or slivers within the project area.

Process Step 2

CC ID: 1132948
Description:

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained lidar elevation and intensity measurements.

The data were in State Plane projection (NAD83, Georgia West), and vertically referenced to NAVD88 using the Geoid 09 model. Both horizontal

and vertical units were in survey feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes:

1. The data were converted from Georgia State Plane coordinates to geographic (NAD83) coordinates.

2. The data were converted from orthometric (NAVD88) heights to ellipsoidal heights (GRS80) using Geoid 09.

3. The data were converted from vertical units of survey feet to meters

4. Elevation outliers were removed.
