2009 Oregon Department of Geology and Mineral Industries (DOGAMI) Oregon Lidar: Willamette Valley
browse graphic The Oregon Department of Geology & Mineral Industries (DOGAMI) 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 in 17 delivery areas from August 31, 2008 through July 1, 2009. See below for the specific date of collection and total area covered for each delivery. This data set covers 3157 square miles (2,020,760 square acres) and falls in portions of the following counties in northwestern Oregon: Benton, Clackamas, Clatsop, Columbia, Lane, Linn, Polk, Marion, Washington, and Yamhill. This data set consists of bare earth and unclassified points. The average pulse density is 8.14 points per square meter over terrestrial surfaces. 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. This LiDAR data set was collected on different dates and organized into 17 deliveries.
