2012 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Upper Naches River, Washington
browse graphic Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data of the Upper Naches River Valley and Nile Slide area of interest on September 30th, 2011-October 1st, 2011 and April 5th, 2012 for the Puget Sound LiDAR Consortium. The valley bottom was reflown in 2012 during ?leaf-off? conditions, to ensure a more detailed bare earth model, and matched with the upslope data from 2011 to provide a seamless dataset. The requested area was expanded to include a 100m buffer to ensure complete coverage and adequate point densities around survey area boundaries. The total acreage of this delivery is 23,771 acres of LiDAR data. The LiDAR survey utilized a Leica ALS60 sensor in a Cessna Caravan 208B. Please see "Project Report" below for specific information regarding the airborne survey and ground survey. This Lidar survey acheived a nominal point spacing of 11.60 points per square meter.
