2001-2002 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Island County and Northeast Jefferson County, Washington
browse graphic 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.
