        abstract:  Watershed Sciences, Inc. collected Light Detection and Ranging (LiDAR) data for the Oregon Department of Geology and Mineral Industries (DoGAMI) and the Oregon Department of Forestry (ODF) between March 15 and November 7 2007. This data set has bare earth and unclassified points. The dataset encompasses portions of the following counties in northwest Oregon: Multnomah, Marion, Hood River, Clackamas, Columbia, Washington and Yamhill. Areas of interest within this data set are the Portland Metro area, Mt. Hood and Silver Falls State Park. There is approximately 8 points per square meter over terrestrial surfaces. 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.
        purpose:  Provide high resolution terrain elevation and land cover elevation data.

            evaluationMethodDescription:  The Root Mean Square Error (RMSE) for this data set is 0.11 feet (3.35 cm) and 0.12 feet (3.65 cm). Because this data set was collected in different deliveries, some areas of the data have an RMSE of 0.11 feet (3.35 cm) and others are 0.12 feet (3.65 cm). Accuracy was assessed using 10632 ground survey (real time kinematic) points. These ground survey points are distributed throughout the entire DoGAMI study area. For more information, please refer to the individual survey reports. They can be accessed via the 'Supplemental' folder associated with this dataset on the Dig. Coast website.

            measureDescription:  LiDAR flight lines have been examined to ensure that there was at least 75% sidelap, there are no gaps between flightlines, and overlapping flightlines have consistent elevation values. Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting. The data was examined at a 1:3500 scale.

                description:  Acquisition. The LiDAR data was collected between March 15 and November 11, 2007. The survey used a Leica ALS50 Pase II laser system mounted in a Cessna Caravan 208, and an Optech 3100 laser system mounted in a Cessna Caravan 208. Near nadir scan angles were used to increase penetration of vegetation to ground surfaces. Ground level GPS and aircraft IMU were collected during the flight.

                description:  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, IPAS Pro GPS/INS software, REALM survey suite, and PosPac 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 and REALM software tools, 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.

                description:  The NOAA Coastal Services Center (CSC) received the files in las format. The files contained Lidar elevation and intensity measurements. The data was in Lambert Conformal Conic and Oregon State Plane projections, and NAVD88 Geoid 03 vertical datum. CSC performed the following processing to the data to make it available within the LDART Retrieval Tool (LDART): 1. The data were converted from Lambert Conformal Conic and Oregon State Plane coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated.

                description:  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 http://www.csc.noaa.gov/digitalcoast/. 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 (http://www.laszip.org/). 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.
