WSI collected Light Detection and Ranging (LiDAR) data for the Oregon LiDAR Consortium (OLC) Scappoose study area. The Scappoose project area encompasses approximately 36,600 acres in Columbia and Washington County, Oregon. The study area is predominantly comprised of rural and forested lands. 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.
Between July 1 and July2, 2013, WSI employed remote-sensing lasers in order to obtain a total area flown of 37,223 acres. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter. The LiDAR survey utilized a Leica ALS60 mounted in a Partenavia P.68. The system was programmed to emit single pulses between 96 and 106 kHz and flown at 900 meters 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.
