        abstract:  The purpose of this project is to provide professional surveying and mapping services for the creation of a high-resolution digital elevation model developed from LIDAR data for Wayne County, Georgia. USGS Contract G10PC00026, Task Order Number G10PD000654
        purpose:  The purpose of this project is to provide professional surveying and mapping services to collect and deliver topographic elevation data derived from multiple return light detection and ranging (lidar) measurements for areas in southeast / coastal Georgia. These data are intended for use in coastal management decision making, including applications such as sea level rise and coastal flood mapping. Lifts were planned to meet project specifications and were 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, and fully Classified LiDAR LAS files. Classified LAS files are used to show the manually reviewed bare earth surface. Any additional classification include Class 1 - unclassified, Class 2 - ground surface, Class 4 - medium Vegetation, Class 5 - High Vegetation, Class 7 - low point (noise) and Class 12 - Overlap points.

                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 model in which the above ground features are removed from the data set. The point cloud was manipulated within the Optech 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. Breaklines were used to reclassify lakes and ponds and inland drains. Data was then run through additional macros to ensure deliverable classification levels matching LAS ASPRS Classification structure. GeoCue functionality was then 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.

                description:  The NOAA Coastal Services Center (CSC) received topographic files in LAS V1.2 format. The data were referenced horizontally to NAD83, State Plane Coordinate System (Georgia East; FIPS 1001) and were vertically referenced to NAVD88 using the Geoid09 model. The horizontal and vertical units of the data were US survey feet. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The data were converted from projected coordinates (Georgia State Plane East) to geographic coordinates (NAD83). 2. The data were converted from orthometric (NAVD88) heights to ellipsoidal heights (GRS80) using Geoid09. 3. The vertical units were converted from US survey feet to meters. 4. The data were converted to LAZ format.

                description:  The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
