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.

Use Limitation These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.
