ASCII xyz point cloud data were produced from remotely sensed, geographically referenced elevation measurements cooperatively by the U.S. Geological Survey (USGS) and National Aeronautics and Space Administration (NASA) along the coasts of Alabama, Florida (Panhandle), Louisiana, Mississippi and Texas in 2001. Dates of collection are: 1. Alabama 20011002-20011004, 20011007-20011010 2. Florida 20011002 3. Louisiana 20010909-20010910 4. Mississippi 20010909-20010910 5. Texas 20011012-20011013 Elevation measurements were collected over the area using the NASA Airborne Topographic Mapper (ATM), a scanning Lidar system that measures high-resolution topography of the land surface. The ATM system is deployed on a Twin-Otter or P-3 Orion aircraft and incorporates a green-wavelength laser operating at pulse rates of 2 to 10 kilohertz. Measurements from the laser ranging device are coupled with data acquired from internal navigation system (INS) attitude sensors and differentially-corrected global positioning system (GPS) receivers to measure topography of the surface at accuracies of 10 to 20 centimeters. 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 elevation maps of the Alabama, Florida (Panhandle), Louisiana, Mississippi, and Texas coastlines for natural resource managers and research scientists. credit: Acknowledgment of the U.S. Geological Survey, Florida Integrated Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. The U.S. Geological Survey and National Aeronautics and Space Administration request to be acknowledged as originators of the dataset in future products or derivative research. Users should be aware that comparisons with other datasets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photo interpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) individualName: Amar Nayegandhi organisationName: Jacobs Technology, U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, St. Petersburg, FL positionName: Computer Scientist contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 727 803-8747 (x3026) facsimile: 727 803-2031 address: (CI_Address) deliveryPoint: 600 4th Street South city: St. Petersburg administrativeArea: FL postalCode: 33701 country: USA electronicMailAddress: anayegandhi@usgs.gov hoursOfService: M-F, 9:00-5:00 EST role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) notPlanned descriptiveKeywords: (MD_Keywords) keyword: Bathymetry/Topography keyword: Airborne Lidar Processing System keyword: ALPS keyword: DEM keyword: Digital Elevation Model keyword: ATM keyword: Airborne Topographic Mapper keyword: laser altimetry keyword: Lidar keyword: remote sensing type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: None date: descriptiveKeywords: (MD_Keywords) keyword: US keyword: Northern Gulf of Mexico keyword: Alabama keyword: Florida keyword: Louisiana keyword: Mississippi keyword: Texas type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: None date: resourceConstraints: (MD_Constraints) useLimitation: These data depict the elevations at the time of the survey and are only accurate for that time.

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 GEOID03 model). The files are in the Quarter-Quad tiling format and the exact tile location is contained in the filename at ########_fs, 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 NASA Airborne Topographic Mapper (ATM) laser scanner collects the data using a green raster scanning laser. The data are stored on hard drives and archived at the U.S. Geological Survey, FISC office in St. Petersburg, FL, and the NASA office at Wallops Flight Facility in Virginia. 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: 2009-08-12T00:00:00 processor: (CI_ResponsibleParty) individualName: Amar Nayegandhi organisationName: Jacobs Technology, U.S. Geological Survey, FISC, St. Petersburg, FL positionName: Computer Scientist contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 727-803-8747 (x3026) address: (CI_Address) deliveryPoint: 600 4th Street South city: St. Petersburg administrativeArea: FL postalCode: 33701 country: USA electronicMailAddress: anayegandhi@usgs.gov hoursOfService: M-F, 8:00-5:00 EST role: (CI_RoleCode) processor processStep: (LE_ProcessStep) description: The NOAA Coastal Services Center (CSC) received the files in LAS format.

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: 2011-04-27T00:00:00 processor: (CI_ResponsibleParty) individualName: Pamela Grothe organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) contactInstructions: Contact Data Center role: (CI_RoleCode) processor return to top metadataMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually dateOfNextUpdate: 2014-05-07 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 2013-05-07T15:16:29.137-06:00 maintenanceNote: Last Metadata Review Date: 2011-11-19 |
