2001-2002 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Island County and Northeast Jefferson County, Washington
This kmz file shows the extent of coverage for the 2001 PSLC Island and NE Jefferson Counties, WA lidar data set.
TerraPoint surveyed and created this data for the Puget Sound LiDAR Consortium under contract. 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.

|Data Presentation Form:||
|Dataset Progress Status||Complete|
|Data Update Frequency:||As needed|
|Purpose:||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.|
