These countywide two-foot contours were derived from LiDAR (Light Detection and Ranging) collected in 2010/2011. This data was collected by Watershed Sciences for the Puget Sound LiDAR Consortium / Puget Sound Regional County. The Joint Base Lewis-McChord liDAR data was collected by Aero-Metric. The 2014 and 2017 updates were collected by Sanborn Mapping Company. Using othophoto comparison, areas of change 2 acres or more were identified and updated using photogrammetric methods that meet the standards for 2-foot contour production. Lidar collection dates are: Mt Rainier National Park - 09/11/2007 to 10/28/2008Lewis County portion near PC Boundary - 04/21/2009 to 07/22/2009Joint Base Lewis-McChord - 01/07/2010 to 01/21/2010Pierce County - 10/19/2010 to 09/06/2012.Update collection dates are: Pierce County - 7/4/2014 to 7/6/2014Pierce County – 7/14/2017 to 7/24/2017The QC on the Lidar (2010/2011) produced contours was completed in 2013.
