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 three deliveries from May 28 - July 27, 2010 and encompasses portions of Deschutes, Klamath, and Lake counties in Oregon. This data set consists of bare earth and unclassified points. The average pulse density is 8.51 pulses per square meter over terrestrial surfaces. The area of interest (AOI) totals 500 square miles (320,041 acres) and the total area flown (TAF) covers 506 square miles (324,020 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. Delivery Area Acquisition Dates AOI Acres TAF Acres 1 May 28 - June 1, 2010 31,380 32,225 2 May 28 - July 27, 2010 159,215 160,744 3 May 28 - July 27, 2010 129,446 131,051 Original contact information: Contact Name: Ian Madin Contact Org: DOGAMI Phone: 971-673-1542 Email: ian.madin@dogami.state.or.us This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
