Elevation measurements were collected over the area using the NASA Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 50 meters per second at an elevation of approximately 300 meters. The EAARL, developed by NASA at Wallops Flight Facility in Virginia, measures ground elevation with a vertical resolution of 15 centimeters. A sampling rate of 3 kHz or higher results in an extremely dense spatial elevation data set. Over 100 kilometers of coastline can be easily surveyed within a 3 to 4 hour mission time period. When subsequent elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development. purpose: The ASCII elevation data can be used to create raster Digital Elevation Models (DEMs). The purpose of this project is to produce highly detailed and accurate digital elevation maps of the post Hurricane Ivan data for use as a management tool and to make this data available to natural resource managers and research scientists. credit: The U.

Converting dense Lidar elevation data into a readily usable format without loss of essential information requires specialized processing. The U. S. Geological Survey's Coastal and Marine Geology (CMG) Program has developed custom software to convert raw lidar data into a GIS compatible map product to be provided to GIS specialists, managers, and scientists. The primary tool used in the conversion process is Advanced Lidar Processing System (ALPS), a multi-tiered processing system developed by a USGS/NASA collaborative project. Specialized processing algorithms are used to convert raw waveform Lidar data acquired by the EAARL to georeferenced spot (x,y,z) returns for "first surface" and "bare earth" topography. These data are then converted to the North American Datum of 1983 and the North American Vertical Datum of 1988 (using the Geoid 03 model). The files are in the Quarter Quad tiling format and the exact tile location is contained in the filename at n88_########_mf_be where ####### is the Quarter Quad tile ID. The development of custom software for creating these data products has been supported by the USGS CMG Program's 'Decision Support for Coastal Parks, Sanctuaries, and Preserves' project. Processed data products are used by the USGS CMG Program's 'National Assessments of Coastal Change Hazards Project' to quantify the vulnerability of shorelines to coastal change hazards such as severe storms, sea-level rise, and shoreline erosion and retreat. return to top distributionInfo: (MD_Distribution) distributionFormat: (MD_Format) name: LAZ version: distributor: (MD_Distributor) distributorContact: (CI_ResponsibleParty) organisationName: DOC/NOAA/NOS/CSC > Coastal Services Center, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 843-740-1200 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave. city: Charleston administrativeArea: SC postalCode: 29405-2413 electronicMailAddress: csc.info@noaa.gov role: (CI_RoleCode) distributor distributionOrderProcess: (MD_StandardOrderProcess) orderingInstructions: The National Geophysical Data Center serves as the archive for this LIDAR data.

The data are stored on hard drives and archived at the U. S. Geological Survey, FISC St. Petersburg office and the NASA office at Wallops Flight Facility. The navigational data are processed at Wallops Flight Facility. The navigational and raw data are then downloaded into the Advanced Lidar Processing System (ALPS). Data are converted from units of time to x,y,z points for elevation. The derived surface data can then be converted into raster data (geotiffs). dateTime: DateTime: 2007-12-01T00:00:00 processor: (CI_ResponsibleParty) individualName: Amar Nayegandhi organisationName: Jacobs Technology, U.

The files contained Lidar elevation and intensity measurements. The data were projected in UTM coordinates (NAD83; Zone 16N) and referenced to the North American Vertical Datum of 1988 (NAVD88) using the Geoid03 model. The following processes were performed to make the data available within the Digital Coast: 1. The data were converted from UTM (NAD83; Zone 17N) to geographic coordinates (NAD83). 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoidal) heights using the Geoid03 model. 3. The data were reclassified to reflect the ASPRS LAS classifications (1 - unclassified, 2 - bare earth). 4. The LAS data were sorted by latitude and the headers were updated. 5. The data were converted to LAZ format. dateTime: DateTime: 2012-01-25T00:00:00 processor: (CI_ResponsibleParty) organisationName: DOC/NOAA/NOS/CSC > Coastal Services Center, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 843-740-1200 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave. city: Charleston administrativeArea: SC postalCode: 29405-2413 electronicMailAddress: csc.info@noaa.gov role: (CI_RoleCode) processor processStep: (LE_ProcessStep) 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. dateTime: DateTime: 2013-01-22T00:00:00 processor: (CI_ResponsibleParty) individualName: Mike Sutherland organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 303-497-6120 facsimile: 303-497-6513 address: (CI_Address) deliveryPoint: NOAA/NESDIS/NGDC E/GC1 325 Broadway city: Boulder administrativeArea: CO postalCode: 80305-3328 country: USA electronicMailAddress: mike.sutherland@noaa.gov hoursOfService: 7:30am-5:00pm Mountain role: (CI_RoleCode) processor return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-01-22 maintenanceNote: This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2013-01-04 version of the FGDC RSE to ISO 19115-2 for LiDAR transform. maintenanceNote: Translated from FGDC 2013-01-22T13:08:19.81-07:00 |
