| 2003 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Yakima County, Washington |
 |
TerraPoint surveyed and created this data for the Puget Sound LiDAR Consortium under
contract. The area surveyed is approximately 77 square miles and covers a portion
of Yakima 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, intensity
classification and return numbers of each point were preserved in the conversion from
ASCII to LAS. ASPRS Classifications were used: Class 1 (Unclassified) and Class 2
(Ground). Futher details are available in the Process Steps below. The NOAA Coastal
Services Center noticed that some intensity values are 0, so be aware before using
the intensity information. This dataset was flown in 2003 with a 50% overlap between
flight lines. Due to the overlap the nominal point spacing of the dataset is 1.0 meter.
