Popis
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 July 5 through September 2, 2010 and encompasses the area around Mt. Shasta in portions of Siskiyou and Shasta counties in California. This data set consists of bare earth and unclassified points. The average pulse density is 10.18 pulses per square meter over terrestrial surfaces. The area of interest (AOI) totals 465 square miles (297,368 acres) and the total area flown (TAF) covers 471 square miles (301,454 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.
