|2009 U.S. Geological Survey (USGS) Lidar: Umpqua River Study Area|
|Watershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data for the U.S. Geological Survey (USGS) Umpqua River study site in collaboration with the Puget Sound LiDAR Consortium (PSLC). The areas for LiDAR collection have been designed as part of a collaborative effort of state, federal, and local agencies in order to meet a wide range of project goals. This LiDAR data set was collected between April 21 - July 13, 2009 and falls in Douglas County, Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.80 pulses per square meter over terrestrial surfaces. The area of interest (AOI) encompasses approximately 67,408 acres and the total area flown (TAF) covers 69,925 acres. The TAF acreage is greater than the original AOI acreage due to buffering and flight planning optimization. In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. Elevation values for open water surfaces are not valid elevation values because few lidar points are returned from water surfaces. Lidar intensity values were also collected.|
