2011 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Rattlesnake
browse graphic Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data on six days between September 15th and November 5th, and from November 6th ? 13th, 2010 for the Puget Sound LiDAR Consortium. This report documents the data acquisition, processing methods, accuracy assessment, and deliverables for the Rattlesnake area of interest in Benton County, WA. The requested areas were expanded to include a 100m buffer to ensure complete coverage and adequate point densities around survey area boundaries. The total acreage of the Rattlesnake AOI is 184,359 acres. The average first-return density of the delivered dataset is 8.3 points per square meter for the Rattlesnake study area. The initial datasets, acquired to be =8 points per square meter, were filtered as described previously to remove spurious or inaccurate points. Additionally, some types of surfaces (i.e., dense vegetation, breaks in terrain, water, steep slopes) may return fewer pulses (delivered density) than the laser originally emitted (native density).
