|2010 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: Crater Lake
||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 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.
