        abstract:  NOAA Contract: EA133C11CQ0009 NOAA Task Order Number: T0013 The PS FY13 GA DNR Elevation Data Task Order involves collecting and delivering topographic elevation point data derived from multiple return light detection and ranging (LiDAR) measurements in 4 counties in Georgia. 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 counties included are Barrow,Clarke, Madison and Oglethorpe. The data collected for these 4 counties will exhibit Hydro Flattened DEMs for inclusion into the National Elevation Dataset (NED). The purpose of the data is for use in coastal management decision making, including applications such as floodplain mapping and water rights management. LiDAR was collected at 1.0 points per square meter (1.0m GSD) for Barrow, Clarke, Madison and Oglethorpe Counties.This area was flown during snow free and leaf-off conditions. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
        purpose:  Lifts are planned to meet project specifications and are flown under cloud-free conditions in order to collect LIDAR points at an average of 1.0 meter point spacing.This allows the user to create Intensity Images, Break Lines, Hydro Flattened DEMs and fully Classified LiDAR LAS files.

                description:  Applanix software was used in the post processing of the airborne GPS and inertial data that is critical to the positioning and the 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 model in 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 2 acres or greater were also collected. Elevation values were assigned to all Inland Ponds and Lakes 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.

                description:  The NOAA Office for Coastal Management (OCM) received the topographic lidar files in LAS format from Photo Science. The files contained lidar elevation measurements and additional information. The data for Barrow and Clarke Counties were received in Georgia State Plane West Zone 1002, NAD83 coordinates. The data for Madison and Oglethorpe were received in Georgia State Plane East Zone 1001, NAD83 coordinates. Both sets of data were vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes:1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid09.2. The topographic las files were converted from a Projected Coordinate System (State Plane) to a Geographic Coordinate System (NAD83).3. The topographic las files' vertical units were converted from feet to meters.4. The topographic las files' horizontal units were converted from feet to decimal degrees.
