Popis
The U.S. Department of Interior, Bureau of Land Management (BLM) contracted with Watershed Sciences, Inc. to collect high resolution topographic LiDAR data for multiple areas within the State of Oregon. 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 on April 7, 2012 and encompasses a portion of Yamhill County in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.91 pulses per square meter over terrestrial surfaces. The area of interest (AOI) encompasses approximately 5,580 acres and the total area flown (TAF) covers 6,137 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.
