2009 Oregon Department of Geology and Mineral Industries (DOGAMI) Oregon Lidar: North Coast
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 11 delivery areas from October 23, 2008 through August 9, 2009. See below for the specific date of collection and total area covered for each delivery. This data set covers 1553 square miles (994,440 square acres) and falls in portions of the following counties in northwestern Oregon: Clatsop, Columbia, Lane, Lincoln, Tillamook, and Washington. This data set consists of bare earth and unclassified points. The average pulse density is 8.61 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 11 deliveries. To determine which delivery or deliveries are in your area of interest, download the Delivery Area graphic at: ftp://ftp.csc.noaa.gov/pub/crs/beachmap/qa_docs/or/north_coast/2009_dogami_oregon_lidar_north_coast.jpg The specific date of collection and total area covered for each delivery are listed below.
