2011 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: Burns 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 from June 19 - 21, 2011 and encompasses a portion of Harney County in Oregon.

This data set consists of bare earth and unclassified points. The average pulse density is 8.25 pulses per square meter over terrestrial surfaces.

The area of interest (AOI) totals 79 square miles (49,083 acres) and the total area flown (TAF) covers 80 square miles (51,401 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.

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

The Root Mean Square Error (RMSE) of the data is 0.03 meters. Accuracy was assessed using 594 RTK (real time

kinematic) ground survey points. These ground survey points are distributed throughout the Burns 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 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.
