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 Pickens, Rockdale and Troup. The purpose of the data is for use in coastal management decision making, including applications such as flood plain mapping and water rights management. LiDAR was collected at 1.0 points per square meter (1.0m GSD) for the portions of Pickens, Rockdale and Troup Counties. This area was flown during snow free and leaf-off conditions. NOAA Contract: EA133C11CQ0009 NOAA Task Order Number: T0013 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. credit: Photo Science, Inc. acquired and post-processed the LiDAR for Pickens, Rockdale and Troup counties. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: https://coast.noaa.gov/htdata/lidar1_z/geoid12a/data/1419/supplemental/2012_PS_Georgia_LiDAR_Footprints.kmz fileDescription: This graphic shows the lidar coverage for Pickens County, Rockdale County and Troup County in Georgia. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: Elevation keyword: LAS keyword: LiDAR keyword: Model keyword: Remote Sensing keyword: Topography/Bathymetry type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: Georgia keyword: Pickens County keyword: Rockdale County keyword: Troup County keyword: US type: (MD_KeywordTypeCode) place descriptiveKeywords: (MD_Keywords) keyword: DEMs - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

Photo Science collected a total of 33 ground control points for use in verifying the vertical accuracy of the classified LiDAR data in Pickens, Rockdale and Troup Counties. These points were tested against the classified LiDAR data and a vertical adjustment was made to the classified LiDAR for each county in order to obtain a higher level of 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.

They are being distributed by NOAA. processStep: (LI_ProcessStep) 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 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. dateTime: DateTime: 2012-01-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received topographic DEM files in ESRI ArcGrid format. The data were converted to GeoTIFF format for ingest into the Digital Coast Data Access Viewer and to comply with the open data policy. Data are in Georgia State Plane West 1002 (NAD83) coordinates and are vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data are US survey feet. dateTime: DateTime: 2012-12-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: DEMs derived from lidar date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: PhotoScience role: (CI_RoleCode) originator source: (LI_Source) sourceCitation: (CI_Citation) title: lidar data date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: PhotoScience role: (CI_RoleCode) originator | |
