Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data for the Department of Geology and Mineral Industries (DOGAMI) and the Oregon Department of Forestry (ODF). The Areas of Interest (AOIs) cover portions of eight counties in northwest Oregon. The extent of requested LiDAR area totals ~1,549,015 acres; the extent of the LiDAR area delivered covers ~1,586,385 acres. The delivered acreage for the study area is greater than the original amount due to buffering of the original AOIs for flight planning optimization.
The LiDAR survey utilized a Leica ALS50 Phase II mounted in Cessna Caravan 208B and an Optech 3100 laser system mounted in a Cessna Caravan 208. The Leica ALS50 Phase II system was set to acquire ≥105,000 laser pulses per second (i.e. 105 kHz pulse rate) and flown at 900 meters above ground level (AGL), capturing a scan angle of ±14o from nadir1. The Optech 3100 system was set to acquire 71,000 laser pulses per second (i.e. 71 kHz pulse rate) and flown at 900 meters above ground level (AGL) capturing a scan angle of ±14 degrees from nadir. These settings are developed to yield points with an average native density of ≥8 points per square meter over terrestrial surfaces. The native pulse density is the number of pulses emitted by the LiDAR system. Some types of surfaces (i.e., dense vegetation or water) may return fewer pulses than the laser originally emitted. Therefore, the delivered density can be less than the native density and lightly variable according to distributions of terrain, land cover and water bodies.
The NOAA Office for Coastal Management (OCM) received 5,163 LAZ files from the Oregon Lidar Comission, with 4158 in Oregon State Plane North projection, and 1,005 in Oregon Lambert projection. These files were processed to the Data Access Viewer (DAV) and https. In addition to the lidar point data, bare earth digital elevation models (DEMs), at 3-foot resolution in ESRI GRID format, created from the lidar point data, are available for download at the link in the Related Items section of this metadata record. Please note that these products have not been reviewed by OCM, and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or OCM.
