The area surveyed is approximately 525 square miles and covers all of Island County, WA and the Northeast portion of Jefferson County, WA. All data was collected during ideal conditions (leaf-off). The LAS files were derived from all returns ASCII files contain the X,Y,Z values of all the LiDAR returns collected during the survey mission. The GPS time, scan angle and return numbers of each point were preserved in the conversion from ASCII to LAS. The LAS files were classified into the following ASPRS classes: (1) Unclassified (2) Bare Earth. Ground and water points are included in Class 2 (Bare Earth). Futher details are available in the Process Steps below. No ancillary data, such as intensity, is available for this data. Initially this dataset was flown in 2001 with a 30% overlap between flight lines which did not meet specifications. The dataset was reflown in 2002 with a 50% overlap between flight lines as the rest of the PSLC data. The data is broken down into USGS quarter quads and then into 25 tiles within each quarter quad. Due to the overlap the nominal point spacing of the dataset is 1.0 meter.The LAS files can be used to create DEMs and also to extract topographic data in software that does not support raster data. Other surface features can also be extracted with custom applications. This high accuracy data can be used at scales up to 1:12000 (1 inch = 1,000 feet). LiDAR data has a wide range of uses such as earthquake hazard studies, hydrologic modeling, forestry, coastal engineering, roadway and pipeline engineering, flood plain mapping, wetland studies, geologic studies and a variety of analytical and cartographic projects.2001010920020323UnknownCompleteasNeeded-122.959139-122.34735048.43436647.892561noneTopography/BathymetryElevationModelLiDARLASRemote SensingNoneUSWashingtonPuget SoundPuget LowlandIsland CountyJefferson CountyWhidbey IslandCamano IslandPort TownsendNoneUse 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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 20130425Mike 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
