2008 USDA Forest Service Lidar: Sandy River Study Area
browse graphicWatershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data for the Sandy River study area in collaboration with the USDA Forest Service. 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 Sept 29 - Oct 1, 2008 and falls mainly in Multnomah County, but also in small portions of Clark and Clackamas Counties, Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.04 pulses per square meter over terrestrial surfaces. The area of interest (AOI) encompasses approximately 34,021 acres and the total area flown (TAF) covers 35,873 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.

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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.
