Popis

In September 2013, WSI, a Quantum Spatial company (QSI), was contracted by the Puget Sound LiDAR Consortium (PSLC) to collect Light Detection and Ranging (LiDAR) data over three areas of interest (AOIs) in the greater Seattle, Washington area. The individual AOIs include the Cedar River Watershed and Floodplain, Lake Youngs Reservoir, and the SCL/Tolt Reservoir, herein all referred to as the Cedar Watershed LiDAR project. This metadata refers to the first delivery of many. Tiles were delivered as state plane orthometric x,y,z values but have since been reprojected/transformed to geographic, ellipsoidal coordinates for OCM use and storage. Original naming conventions will apply to the FTP available data. The average first-return density of LiDAR data for the Cedar Watershed LiDAR project was 1.15 points per sq. ft (12.41 points per sq m) while the average ground classified density was 0.25 points per sq. ft (2.67 points per sq m)
