2010 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: Klamath Study Area

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 over six deliveries from September 14 through October 27, 2010 and encompasses portions of Klamath

and Lake counties in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.61 pulses

per square meter over terrestrial surfaces. The area of interest (AOI) totals 1054 square miles (674,756 acres) and the total area

flown (TAF) covers 1083 square miles (692,999 acres). The TAF acreage is greater than the original AOI acreage due to buffering

and flight planning optimization. This metadata record reflects all the data and cumulative statistics for the overall lidar survey.

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.

Dates of acquisition for the six deliveries that make up this data set.

Not specified in final report, assumed to be 1 m.

The Root Mean Square Error (RMSE) of the data is 0.03 meters (0.11 ft). Accuracy was assessed using 6,862 ground survey (real time

kinematic) points. These ground survey points are distributed throughout the OLC Klamath study area.

LiDAR data has been collected and processed for all areas within the project study area.

LiDAR flight lines have been examined to ensure that there was at least 50 percent sidelap, there are no gaps between flightlines, and

overlapping flightlines have consistent elevation values. Shaded relief images have been visually inspected for data errors such as

pits, border artifacts, gaps, and shifting. The data were examined at the 1:3000 scale.
