CZMIL integrates a lidar sensor with topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. The 3-D position data are used to generate a series of gridded file products, which are tiled into quarter-quads. The preliminary data file naming convention is based on a quarter-quad number, collection date, collection start time, processing session letter, local project name, and data product type. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID12A model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record. purpose: These data were collected as a part of the 2012 Post Superstorm Sandy effort to depict the elevations above and below water along the New York coastal zone. The data will be used by the USACE to generate digital elevation models and contours for use in, damage assessment to USACE projects, engineering design and design reviews, conservation planning, research, delivery, floodplain mapping, and hydrologic modeling utilizing LiDAR technology. The task order required that the LiDAR data was to be acquired within six (6) days of receiving Notice to Proceed (NTP). The project data will consist of high accuracy classified bare-earth LiDAR data in LAS format well as raster digital elevation models per task order requirements. The specifications are based upon the U.S. Geological Survey National Geospatial Program Lidar Base Specifications 1.0, which may be viewed at http://pub.usgs.gov/tm/11b4/. credit: U.S. Army Corps of Engineers (USACE), JALBTCX (Joint Airborne Lidar Bathymetry Technical Center of eXpertise) 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://coast.noaa.gov/htdata/lidar1_z/geoid18/data/1436/supplemental/2012_USACE_PostSandy_LongIsland_footprint.KMZ fileDescription: This graphic shows the post Sandy LiDAR coverage for eastern Long Island, New York fileType: KMZ descriptiveKeywords: (MD_Keywords) keyword: DOD/USARMY/USACE/SAM/MOBILE type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: GCMD Data Center Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: HUMAN DIMENSIONS > LAND USE/LAND COVER > LAND USE CLASSES keyword: OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > BATHYMETRY keyword: SOLID EARTH > GEOMORPHOLOGY > COASTAL LANDFORMS/PROCESSES type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: GCMD Earth Sciences Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: LIDAR > LIGHT DETECTION AND RANGING type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: GCMD Instrument Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Land Surface > Topography > Terrain Elevation keyword: Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography keyword: Earth Science > Oceans > Coastal Processes > Coastal Elevation keyword: elevation type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Long Island type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Geographic Names Information System date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Continent > North America > United States Of America keyword: Continent > North America > United States Of America > New York keyword: Vertical Location > Land Surface keyword: Vertical Location > Seafloor type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Location Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Earth Remote Sensing Instruments > Active Remote Sensing > Profilers/Sounders > Lidar/Laser Sounders > LIDAR > Light Detection and Ranging type: (MD_KeywordTypeCode) instrument thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Instrument Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Aircraft > Aircraft type: (MD_KeywordTypeCode) platform thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Platform Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: BareEarth 1m Raster keyword: Bathymetry keyword: Coastal Zone Mapping and Imaging Lidar (CZMIL) keyword: Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX) keyword: Mobile District keyword: National Coastal Mapping Program (NCMP) keyword: Topography keyword: U.S. Army Corps of Engineers (USACE) keyword: ncdbNcmpRaster type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: U.S. Coastline type: (MD_KeywordTypeCode) place descriptiveKeywords: (MD_Keywords) keyword: DEMs -

OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https. processStep: (LI_ProcessStep) description: Using an Optech Gemini LiDAR Sensor, 21 flight lines of high density data, at a nominal pulse spacing (NPS) of 1 meter, were collected along the Eastern Long Island, New York (approximately one hundred sixteen (116) square miles). Data Acquisition Height = 5,500 feet AGL - Aircraft Speed = 125 Knots. Multiple returns were recorded for each laser pulse along with an intensity value for each return. A total of two (2) missions were flown during a period from November 14, 2012 through November 15, 2012. One airborne global positioning system (GPS) base station was used in support of the LiDAR data acquisition. Eighteen (18) ground control points were surveyed through static methods. The geoid used to reduce satellite derived elevations to orthometric heights was Geoid12A. Data for the task order is referenced to the UTM Zone 18N, North American Datum of 1983 (NAD83), and NAVD88, in Meters. Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line. The coverage was classified to extract a bare earth digital elevation model (DEM) and separate last returns. In addition to the LAS deliverables, one layer of coverage was delivered in the ArcGrid Format: bare-earth. dateTime: DateTime: 2012-11-14T00:00:00 processStep: (LI_ProcessStep) description: The LiDAR system calibration and system performance is verified on a periodic basis using Woolpert's calibration range. The calibration range consists of a large building and runway. The edges of the building and control points along the runway have been located using conventional survey methods. Inertial measurement unit (IMU) misalignment angles and horizontal accuracy are calculated by comparing the position of the building edges between opposing flight lines. The scanner scale factor and vertical accuracy is calculated through comparison of LiDAR data against control points along the runway. Field calibration is performed on all flight lines to refine the IMU misalignment angles. IMU misalignment angles are calculated from the relative displacement of features within the overlap region of adjacent (and opposing) flight lines. The raw LiDAR data is reduced using the refined misalignment angles. dateTime: DateTime: 2012-11-14T00:00:00 processStep: (LI_ProcessStep) description: Once the data acquisition and GPS processing phases are complete, the LiDAR data was processed immediately to verify the coverage had no voids. The GPS and IMU data was post processed using differential and Kalman filter algorithms to derive a best estimate of trajectory. The quality of the solution was verified to be consistent with the accuracy requirements of the project. dateTime: DateTime: 2012-11-16T00:00:00 processStep: (LI_ProcessStep) description: The individual flight lines were inspected to ensure the systematic and residual errors have been identified and removed. Then, the flight lines were compared to adjacent flight lines for any mismatches to obtain a homogenous coverage throughout the project area. The point cloud underwent a classification process to determine bare-earth points and non-ground points utilizing "first and only" as well as "last of many" LiDAR returns. This process determined Default (Class 1), Ground (Class 2),Noise (Class 7), Model Key Points (Class 8), and Overlap (Class 12) classifications. The bare-earth (Class 2 - Ground) LiDAR points underwent a manual QA/QC step to verify that artifacts have been removed from the bare-earth surface. The surveyed ground control points are used to perform the accuracy checks and statistical analysis of the LiDAR dataset. dateTime: DateTime: 2012-11-16T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received GeoTiff format files from USACE JALBTCX for the Long Island, NY project area. The bare earth raster files were at a 1 m grid spacing. The data were in geographic NAD83 coordinates and NAVD88 (Geoid12A) elevations in meters. OCM assigned the appropriate EPSG codes (Horiz - 4269, Vert - 5703) and copied the raster files to https for Digital Coast storage and provisioning purposes. dateTime: DateTime: 2021-11-17T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: USACE JALBTCX date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: USACE JALBTCX role: (CI_RoleCode) originator | |
