|2005 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Lewis County
||Terrapoint collected Light Detection and Ranging (LiDAR) data for the Lewis County
project of 2005. The project site covered approximately 223 square miles, divided
into two blocks: southern block 213 Square Miles, northern block 10 Square Miles.
The field data collection took place from December 11th, 2004 to January 30th, 2005.
LIDAR data was collected on 12/11/2004, 12/12/2004, 12/15/2004, 1/20/2005, 1/21/2005,
1/24/2005 and 1/30/2005. The control network and check point surveys were established
from December 11th to December 23rd, 2004. The Airborne LiDAR survey was conducted
using Terrapoint?s 40 kHz ALTMS (Airborne Laser Terrain Mapping System), flying at
an optimum height of 3500 ft AGL at 140 knots. The system consists of a 36-degree
full angle laser, a Trimble 4700 GPS receiver and a Honeywell H764 IMU unit. This
metadata is a collaboration of metadata reports from each of the individual 15 projects.
The Puget Sound Lowlands project covers more areas over 2000-2004, these areas were
excluded for this project.
