By positioning laser range finding with the use of 1 second GPS with 100hz inertial measurement unit corrections Terrapoint's LIDAR instruments are able to make highly detailed geospatial elevation products of the ground, man-made structures and vegetation. The LiDAR flightlines for this project were planned for a 50% acquisition overlap. The nominal resolution of this project without overlap is 1.37m spacing, but effectively is 2.74m with overlap factored. Four returns were recorded for each pulse in addition to an intensity value. GPS Week Time, Flightline number and scan angle attributes were provided for each LiDAR point. Data is provided as random points, in LAS v1.0 format, classified according to ASPRS Class Code 1= Undefined, 2=Ground.The purpose of this LiDAR data is to produce high accuracy 3D elevation based geospatial products for Middlesex County, New Jersey.2006100820061011UnknownCompletenotPlanned-74.632358-74.20155840.61036640.249866NoneBathymetry/TopographyASPRS standardsDEMdigital elevation modelelevationLAS_v1.0laserLiDAROPTECH_3100EAsurface modelNoneUSNew JerseyMiddlesex CountyNoneUse 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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 20130611Mike 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
