|2007 Oregon Department of Geology and Mineral Industries (DoGAMI) LiDAR: Northwest
Oregon and Portland Metro Area
|Watershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data for the
Oregon Department of Geology and Mineral Industries (DoGAMI) and the Oregon Department
of Forestry (ODF) between March 15 and November 7 2007. This data set has bare earth
and unclassified points. The dataset encompasses portions of the following counties
in northwest Oregon: Multnomah, Marion, Hood River, Clackamas, Columbia, Washington
and Yamhill. Areas of interest within this data set are the Portland Metro area, Mt.
Hood and Silver Falls State Park. There is approximately 8 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.
