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.LIDAR data is used for 3D visualization, elevation based analysis and for feature extraction.2007010320070509UnknownCompleteunknown-79.109826-78.41165343.39188742.999853NoneBathymetry/TopographyElevationLiDARTopographyDigital Elevation ModelDEMSurface ModelNoneUnited StatesNew YorkNiagara CountyLake OntarioNoneUse Limitation: These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.; Use Limitation: While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.; DOC/NOAA/NOS/CSC > Coastal Services Center, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of Commercephysical and mailing 2234 South Hobson Ave. CharlestonSC29405-2413843-740-1200csc.info@noaa.govUnknown DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of CommerceMike Sutherlandphysical and mailing NOAA/NESDIS/NGDC E/GC1 325 Broadway BoulderCO80305-3328303-497-6120mike.sutherland@noaa.govUnknown 20130607Mike SutherlandDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commercemailing and physical NOAA/NESDIS/NGDC E/GC1 325 Broadway BoulderCO80305-3328303-497-6120mike.sutherland@noaa.govContent Standard for Digital Geospatial Metadata: Extensions for Remote Sensing MetadataFGDC-STD-012-2002
