Overview

Watershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data of Western Lewis County for the Puget Sound LiDAR Consortium. This data set covers approximately 400 square miles. Data was collected in leaf-off conditions. An Optech 3100 LiDAR system was mounted in a fixed-wing aircraft and flown 1,200 meters above ground level (AGL). A pulse repetition frequency (PRF) of 71 kHz with at least 100% overlap (minimum 50% side-lap) was used. This data set acheived greater than 8 points per square meter. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
