WSI collected Light Detection and Ranging (LiDAR) data for the Oregon LiDAR Consortium (OLC) Clackamol 2013 study area in Clackamas and Marion County, Oregon. The collection of high resolution geographic data is part of an ongoing pursuit to amass a library of information accessible to government agencies as well as the general public. The study area is predominantly comprised of rural and forested lands, including the Clackamas River, Timothy Lake, and Silver Creek Reservoir. Between May 1 and May 6, 2013 and again between July 8 and July 20, 2013, WSI employed remote-sensing lasers in order to obtain a total area flown of 80,504 acres. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter. Three delivery areas totaled 443,535 acres. The LiDAR survey utilized a Leica ALS60 mounted in a Cessna Caravan 208B. The systems were programmed to emit single pulses at around 100 kHz and flown at 900 m AGL, capturing a scan angle of 15 degrees from nadir. These settings were developed to yield points with an average native density of greater than eight pulses per square meter over terrestrial surfaces. Final products included lidar point cloud data, one-meter digital elevation models of bare earth ground model and highest-hit returns, intensity rasters, study area vector shapes, and corresponding statistical data. Final deliverables were projected in Oregon Statewide Lambert Conformal Conic. Lidar point clouds were projected back to geographic coordinates for storage in the Digital Coast Data Access Viewer.
