Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data on the Quinault watershed survey area for the Puget Sound LiDAR Consortium. This data set covers approximately 181 square miles. Due to spring snow on the ground WSI was unable to acquire data for the complete survey during the initial flights in April and will return to finish acquisition at a later date. Delivery 1 of the survey area was collected on March 24th and 25th and April 8th and 9th and 22nd.
The LiDAR survey utilized both a Leica ALS60 and a Leica ALS50-II sensor in a Cessna Caravan 208B.All areas were surveyed with an opposing flight line side-lap of =60% (=100% overlap) to reduce laser shadowing and increase
surface laser painting. The Leica laser systems allow up to four range measurements (returns) per pulse, and all discernible laser returns were processed for the output dataset.
This LiDAR survey achieved a nominal point spacing of 9.23 points per square meter.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
