50057 usace2006_ec_m34_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed 2006-11-14 These data were collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise using the CHARTS system. The data includes hydrographic and topographic data. The data were collected in Dec 2005-Feb 2006 for the coasts of South Carolina, Georgia and the Atlantic coast of Florida. Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov These data were collected as a part of the National Coastal Mapping Program to depict the elevations above and below water along the east coastal zone. 10701 Theme ISO 19115 Topic Category elevation Temporal December 2005 Temporal February 2006 Temporal January 2006 Office for Coastal Management Charleston SC Data Set As Needed Any conclusions drawn from analysis of this information are not the responsibility of NOAA, the Office for Coastal Management or it's partners.

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 3.0m. ; Quantitative Value: 3.0 meters, Test that produced the value: 2 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.30m. ; Quantitative Value: 0.30 meters, Test that produced the value: 2 Sigma Cloud Cover: Unknown These data covered the required survey area with minimal gaps in data coverage. The data postings are very consistent with postings at about 1.3m density. Lidar data between different flight lines matched within 0.20 meters Eastcoast Shoreline Mapping Range 2005-12-11 2006-02-05 This is an xyz dataset collected and provided by CESAM-OP-J, JALBTCX. | Source Geospatial Form: globe | Type of Source Media: disc 1 These data were collected using a SHOALS-1000T system. It is owned and operated by Fugro Pelagos performing contract survey services for the US Army Corps of Engineers. The system collects topographic lidar data at 10kHz and hydrographic data at 1kHz. The system also collects RGB imagery at 1Hz. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V equipment. Raw data are collected and transferred to the office for downloading and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the dataset. The edited data are unloaded from SHOALS GCS, converted from ellipsoid to orthometric heights, based on the GEOID03 model, and split into greographic tiles covering approximately 5km each. 2006-04-24T00:00:00 2 The NOAA Office for Coastal Management (OCM) received files in ascii format. The files contained lidar intensity and elevation measurements. OCM performed the following processing on the data to make it available within the Lidar Data Retrieval Tool (LDART): 1. Each hydro/topo last return ascii file was converted to las files. Default values for which there is no corresponding input were assigned as follows for each las elevation data record: intensity = 0, retn = 1, nret = 1, class = 0 2. The las files were sorted by latitude and the las header fields were updated. 2006-07-15T00:00:00 3 For data managment purposes, the Office for Coastal Management converted the data from NAVD88 elevations to ellipsoid elevations using Geoid 03. 2008-02-01T00:00:00 gov.noaa.nmfs.inport:50057 Anne Ball 2017-11-15T15:24:01 SysAdmin InPortAdmin 2022-08-09T17:11:37 2022-03-16 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
