2011 Oregon Department of Geology and Mineral Industries (DOGAMI) Lidar: US Forest Service (FS) Newberry Study Area

browse graphicThis kmz file shows the extent of coverage for the 2011 DOGAMI US Forest Service Newberry lidar data set.
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 July 31 - August 10, 2011 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 10.2 pulses per square meter over terrestrial surfaces. The area of interest (AOI) totals 444 square miles (284,030 acres) and the total area flown (TAF) covers 462 square miles (296,074 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. FS (US Forest Service)

    Use Limitations
    • These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.

    Processing Steps
    • No metadata for the lidar point data was provided to NOAA CSC with this data set. The following process step contains information derived from the metadata of other Watershed Sciences, Inc. data sets and from the FS Newberry Study area lidar report. This lidar report may be accessed at: Acquisition 1. Lidar data acquisition began July 31, 2011 and was completed August 10, 2011. 2. The survey used both a Leica ALS50 Phase II and a Leica ALS60 laser system mounted in a Cessna Caravan 208B. 3. Near nadir scan angles were used to increase penetration of vegetation to ground surfaces. 4. Ground level GPS and aircraft IMU were collected during the flight. Processing 1. Flight lines and data were reviewed to ensure complete coverage of the study area and positional accuracy of the laser points. 2. Laser point return coordinates were computed using ALS Post Processor software and IPAS Pro GPS/INS software, based on independent data from the LiDAR system, IMU, and aircraft. 3. The raw LiDAR file was assembled into flight lines per return with each point having an associated x, y, and z coordinate. 4. Visual inspection of swath to swath laser point consistencies within the study area were used to perform manual refinements of system alignment. 5. Custom algorithms were designed to evaluate points between adjacent flight lines. Automated system alignment was computed based upon randomly selected swath to swath accuracy measurements that consider elevation, slope, and intensities. Specifically, refinement in the combination of system pitch, roll and yaw offset parameters optimize internal consistency. 6. Noise (e.g., pits and birds) was filtered using ALS postprocessing software, based on known elevation ranges and included the removal of any cycle slips. 7. Using TerraScan and Microstation, ground classifications utilized custom settings appropriate to the study area. 8. The corrected and filtered return points were compared to the RTK ground survey points collected to verify the vertical and horizontal accuracies. 9. Points were output as laser points, TINed and GRIDed surfaces
    • The NOAA Coastal Services Center (CSC) received the files in las format. The files contained LiDAR elevation and intensity measurements. The data were in OGIC HARN, Oregon Statewide Lambert Conformal Conic Projection (NAD83/HARN), NAVD88 (Geoid03) vertical datum and International Feet. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The data were converted from OGIC HARN, Oregon Statewide Lambert Conformal Conic Projection (NAD83/HARN) to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid03. 3. The data were converted from International Feet to meters. 4. The data were sorted by time. 5. The data were converted to laz format.
    • The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg ( The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
