|2012 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Chehalis River Watershed
||Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data
for the Chehalis River Watershed study area on January 28th, February 2nd-7th, March
4th-9th, March 21st-23rd, and April 7th, 2012. Acquisition days were not consecutive
due to weather. Data was collected for the Puget Sound LiDAR Consortium in partnership
with the Federal Emergency Management Agency Region X (FEMA), Washington Department
of Natural Resources, and Lewis County. The requested area of 224,713 acres for the
Chehalis River Watershed was expanded to include a 100m buffer to ensure complete
coverage and adequate point densities around survey area boundaries resulting in a
total of 234,556 acres of delivered LiDAR data. The LiDAR survey utilized an Optech
Orion-C and a Leica ALS60 sensor in a Cessna Caravan 208B. Please see "Project Report"
below for specific information regarding the airborne survey and ground survey. This
Lidar survey acheived a nominal point spacing of 10.94 points per square meter.
