2009-2010 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: USGS Wenas Valley
browse graphic The dataset encompasses portions of Wenas Valley in Kitittas and Yakima Counties, Washington. The bare earth digital elevation models (DEMs) represent the earth's surface with all vegetation and human-made structures removed. The bare earth DEMs were derived from LiDAR data using TIN processing of the ground point returns. Some elevation values have been interpolated across areas in the ground model where there is no elevation data (e.g. over dense vegetation). The DEM grid cell size is 3-ft. The projection is NAD83 (HARN) Washington State Plane, South. The elevation units are in U.S. Survey Feet. Watershed Sciences, Inc. collected the LiDAR and created this data set for the Puget Sound LiDAR Consortium. Watershed Sciences, Inc. (WS) initially collected 37,969 acres of Light Detection and Ranging (LiDAR) data of the Wenas Valley area of interest (AOI) in Kittitas and Yakima Counties, WA on October 28th, 2009. This data was delivered on November 21st, 2009. After the AOI was clear of snow, the remaining 110,255 acres were collected on March 22nd and from June 12th to June 16th, 2010. The total deliverable area including a 100 m buffer is 148,224 acres.
