2012 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Hoh River Watershed, Washington (Delivery 1)
browse graphic Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data on the Hoh River watershed survey area for the Puget Sound LiDAR Consortium and the Hoh Tribe Department of Natural Resources. 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 April 14th, 15th, 17th, 19th, 20th and 21st. 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 acheived a nominal point spacing of 8.4 points per square meter.
