|2011 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: Ochoco Study
||The Oregon Department of Geology and 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 July 8 - 16, 2011
and encompasses portions of Wheeler, Crook, and Grant counties in Oregon. This data
set consists of bare earth and unclassified points. The average pulse density is 9.74
pulses per square meter over terrestrial surfaces. The area of interest (AOI) encompasses
192,576 acres and the total area flown (TAF) covers 196,450 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.
