Total, approximately 555 square miles were collected at a nominal point spacing of 1.4 meters and based on the Sanborn FEMA compliant LiDAR product specification. The lidar data was collected from Jan 3 2007-May 9 2007. Multiple returns were recorded for each laser pulse along with an intensity value for each return. The lidar points in this data set are the last return data, it is not a bare earth data set and the points have not been classified. LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform. Using a combination of laser range finding, GPS positioning and inertial measurement technologies; LIDAR instruments are able to make highly detailed Digital Elevation Models (DEM) of the earth's terrain, man-made structures and vegetation. This data was collected at a resolution to aid in coastal management decisions including flood plain analysis and mapping. purpose: LIDAR data is used for 3D visualization, elevation based analysis and for feature extraction. credit: Acknowledgement of the Federal Emergency Management Agency (FEMA), Sanborn Map Company, Inc, and Medina Consultants would be appreciated in products derived from these data. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: Federal Emergency Management Agency, Region II contactInfo: (CI_Contact) address: (CI_Address) deliveryPoint: 26 Federal Plaza city: New York administrativeArea: NY postalCode: 10278 country: U.S. role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) unknown descriptiveKeywords: (MD_Keywords) keyword: Bathymetry/Topography keyword: Elevation keyword: LiDAR keyword: Topography keyword: Digital Elevation Model keyword: DEM keyword: Surface Model type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: None date: descriptiveKeywords: (MD_Keywords) keyword: United States keyword: New York keyword: Niagara County keyword: Lake Ontario 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.

Some energy may continue beyond this initial surface to be reflected by a subsequent surface as represented by the Last Return data. Intensity information is captured from the Reflective Surface pulse and indicates the relative energy returned to the sensor as compared to the energy transmitted. The Intensity image is not calibrated or normalized but indicates differences in energy absorption due to the interaction of the surface materials with laser energy at the wavelength transmitted by the sensor. 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.

LIDAR is self-illuminating and has minimal cloud penetration capability. Water vapor in steam plumes or particulates in smoke may cause reflection of LIDAR signals and loss of elevation information beneath these plumes. Glass structures and roofs may appear transparent to the LIDAR signal and therefore may not register on the reflective surface. Some asphalt formulations have been shown to absorb topographic LIDAR wavelength energy resulting in "pitting" of roof surfaces using this material. result: report: (DQ_ConceptualConsistency) measureDescription: All LAS formatted LIDAR data are validated using commercial GIS software to ensure proper formatting and loading before delivery. This validation procedure ensures that data on delivery media is in correct physical format and is readable. result: lineage: (LI_Lineage) processStep: (LE_ProcessStep) description: 1.

The files contained Lidar elevation and intensity measurements. The data were in State Plane New York West, FIPS 3103 coordinates, horizontal units of measure of US survey feet and in NAVD88 Geoid 03 vertical datum with vertical units of measure of feet. CSC performed the following processing to the data to make it available within the Digital Coast: 1. The data were converted from NY State Plane coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated. 4. The data were filtered to remove outliers. dateTime: DateTime: 2009-03-25T00:00:00 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: 2009-07-28T00:00:00 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: 2014-06-07 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 2013-06-07T12:41:52.276-06:00 maintenanceNote: Last Metadata Review Date: 2011-11-19 |
