Dataset Identification:
- 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 August 23, 24, 31, Sept 2 - 5, 2010 and falls mainly in Klamath County, and very small portions of Douglas and Jackson counties in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.39 pulses per square meter over terrestrial surfaces. The area of interest (AOI) totals 283 square miles (181,081 acres) and the total area flown (TAF) covers 308 square miles (197,011 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.

Data quality information
Scope of quality information
- name Of Measure Horizontal Positional Accuracy Report
- evaluation Method Description Not specified in final report, assumed to be 1 m.
- name Of Measure Vertical Positional Accuracy Report
- evaluation Method Description The Root Mean Square Error (RMSE) of the data is 0.05 meters. Accuracy was assessed using 1,512 ground survey RTK (real time kinematic) points. These ground survey points are distributed throughout the Crater Lake study area. The final LiDAR Report for the Crater Lake study area may be accessed at: ftp://coast.noaa.gov/pub/DigitalCoast/lidar1_z/geoid12a/data/1428/supplemental/OLC_Crater_Lake.pdf
- evaluation Method Description LiDAR data has been collected and processed for all areas within the project study area.
- measure Description LiDAR flight lines have been examined to ensure that there is at least 50% sidelap, that there are no gaps between flightlines, and that overlapping flightlines have consistent elevation values. Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting.
