The LiDAR data was acquired across the project area of Dorchester County, SC. The lidar data acquisition was executed in 5 sessions, from March 5 to March 7, 2007, using a Leica ALS50(83) Lidar System. The airborne GPS (ABGPS) base stations supporting the LiDAR acquisition consisted of the bases set up by the flight crews at KDYB Airport. Dual Frequency data was logged continuously for the duration of each LiDAR flight mission at a one-second sampling rate or better. The flight plan for LiDAR consisted of parallel flights in a north-south extent across the site. Ninety-seven (97) flight lines of LiDAR data were acquired. No problems were encountered during the LiDAR data acquisition phase of the project which would adversely affect the final accuracy, nor schedule of the final deliverables. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. purpose: High density LiDAR data acquisition within the project limits at a sufficient altitude and density to support digital terrain model (DTM) development for 2-foot contours with a vertical accuracy of 1.2-feet at the 95 percent confidence level. 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: NOAA Office for Coastal Management 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: NOAA Office for Coastal Management 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://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/5106/supplemental/sc2007_scdnr_dorchester_m5106.kmz fileDescription: This graphic shows the lidar coverage for the 2007 lidar project covering Dorchester County, South Carolina. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: 2007 type: (MD_KeywordTypeCode) temporal descriptiveKeywords: (MD_Keywords) keyword: Lidar - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: This data set was compiled dynamically.

The resultant file is in a LAS binary file format. The LAS file version 1.1 formats can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and GRS80 vertical datum. The date and time for each flight line can be determined using the Julian date and time. The Julian date is a continuous count of days and fractions since noon Universal Time on January 1, 4713 BCE on the Julian calendar. dateTime: DateTime: 2009-01-01T00:00:00 processStep: (LI_ProcessStep) description: The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters is applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. dateTime: DateTime: 2009-01-01T00:00:00 processStep: (LI_ProcessStep) description: Conversion from Geodetic coordinates NAD83 into State Plane coordinates (International Feet) NAD83 and conversion from ellipsoid heights (meters) into orthometric heights (U.S. Survey Feet). dateTime: DateTime: 2009-01-01T00:00:00 processStep: (LI_ProcessStep) description: Sanborn used GeoCue software to develop LiDAR stereo models.

The files contained lidar elevation and intensity measurements. The data were in State Plane Zone 3900, NAVD88 (orthometric) heights in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The data were converted from State Plane coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights in meters to GRS80 (ellipsoid) heights in meters using Geoid 09. 3. Erroneous elevations were removed. dateTime: DateTime: 2016-10-17T00:00:00 processStep: (LI_ProcessStep) description: The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. dateTime: DateTime: 2025-06-24 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
