        abstract:  The Columbia River Light Detection and Ranging (LiDAR) survey project was a collaborative effort to develop detailed high density LiDAR terrain data for the US Army Corps of Engineers (USACE). The LiDAR will be used to support hydraulic modeling work associated with proposed 2014 Columbia River treaty negotiations. The dataset encompasses approximately 2836 square miles of territory in portions of Oregon, Washington, Idaho and Montana within the Columbia River drainage. This survey was under the jurisdiction of three Corps districts: Portland (CENWP), Seattle (CENWS), and Walla Walla (CENWW). CENWP was the project lead and primary contracting organization. Bare earth point data are classified as either ground (2), model key point (8) or water (9) and represent the earth's surface with all vegetation and human-made structures removed. Model key points were generated to represent the bare earth surface within a 0.07 m tolerance. Ground points (class 2) are the remaining ground points not classed as model key. Both ground and model key classes are needed for display of all bare earth points. Water classification was used for those bare earth/ground classified points that fell inside a water boundary as determined using softcopy photogrammetry with stereograms generated from LiDAR intensities. All remaining points received the default classification (1). In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. The RMSE of the data for open, hard-packed surfaces is 0.046 meters as assessed from 40,266 ground survey (real time kinematic) points taken on hard-packed road surfaces. This value is representative of anticipated accuracies in open, evenly sloped or flat terrain where maximum point densities were achieved. The project was completed for the US Army Corps of Engineers, Portland District, to support hydraulic modeling related to the ACOE Columbia River Treaty project. Data acquisition, bare earth processing, and development of final tiled LiDAR deliverables and DEM's was performed by Watershed Sciences, Inc. Overall project management, photogrammetric quality control review using LiDAR stereograms, water delineation and breakline development was performed by David C. Smith & Associates, Inc. Professional Surveyor oversight of ground control data, ground control data processing and ground control publication was performed by David Evans and Associates, Inc. Final quality control review in ArcGIS of all final deliverables, including preparation of point density rasters and reach based geo-databases incorporating all deliverables, was performed by CC Patterson and Associates. NOTE ON DATUM ISSUES: All ground control and subsequent LiDAR data deliverables were developed and delivered at NAD '83 CORS 96 horizontal and NAVD '88 Geoid '09 vertical datums as processed in OPUS-DB. Due to limitations in the transformations supported by ESRI, NAD '83 and NAVD '88 datums were temporarily assigned to the ESRI deliverables and ESRI .prj file even though the actual coordinate values in the data files are at the original NAD '83 CORS 96 and NAVD '88 Geoid '09 datums. In many instances, a temporary assignment of NAD '83 HARN or HPGN may better approximate local conditions. Plain NAD '83 was used for the primary deliverable in order to avoid any implication of higher precision; however, the user may want to evaluate other approximations for specific applications. At such time as ESRI includes support for NAD '83 CORS '96, the temporary NAD '83 assignment in the .prj file should be replaced with NAD '83 CORS '96 without further reprojection. The NOAA Coastal Services Center has converted the data to ellipsoid heights (using Geoid09) and NAD 83 geographic coordinates for data storage and Digital Coast provisioning purposes.
        purpose:  Provide high resolution terrain elevation and land cover elevation data for the purpose of supporting hydraulic modeling related to the Columbia River Treaty Project.

Vegetated areas could not be assessed using softcopy photogrammetry methods and may not meet this accuracy in all cases. Open, hard pavement areas significantly exceed this requirement. The RMSE of the data for open, hard-packed surfaces is 0.046 meters as assessed from 40,266 ground survey (real time kinematic) points taken on hard-packed road surfaces.

This value is representative of anticipated accuracies in open, evenly sloped or flat terrain where maximum point densities were achieved. To assess accuracies in other terrain conditions, a detailed photogrammetric review using LiDAR stereograms was conducted. The review was focused on significant and readily identifiable features of 0.5 m height or larger. Areas where the initial ground model point densities did not appear to support the 13 cm RMSE target accuracy were identified and corrected with supplemental breaklines to create an integrated terrain model designed to meet accuracy requirements.

            measureDescription:  LiDAR flight lines have been examined to ensure that there was at least 60% sidelap; there are no gaps between flightlines, and overlapping flightlines have consistent elevation values. Professional surveyor oversight was implemented for the base station control survey. All control point data was reviewed by a professional surveyor, processed for and NGS OPUS DB solution and for inclusion in the database. 10% of the field points were verified by an independent GPS survey quality control check. All new monuments were submitted for publication on the OPUS online datasheet website. Ground point classifications were reviewed in detail both by visual review during the initial LiDAR processing and again during a photogrammetric review against stereograms generated from first return LiDAR intensities. Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting. The data was examined at a 1:2000 scale. An overall review including mosaicing all imagery and developing a geodatabase of all .las files, raster and vector deliverables was performed as a final quality control check.

                description:  Acquisition The LiDAR data was collected between November 16th, 2009 and July 2, 2010. The survey used both the Leica ALS50 Phase II and ALS 60 laser systems 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:  Point Cloud 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, and Waypoint GPS, 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.

                description:  Water Delineation and Breakline Integration 1) Photogrammetric review and evaluation of ground class model key points was performed using stereograms generated from LiDAR first return intensities using softcopy photogrammetry equipment. 2) Stereograms were generated at a 0.3 meter pixel resolution to support softcopy photogrammetry measurements. Based on an initial test of approximately 30 test points on hard flat surfaces, the softcopy photogrammetry measurements were found to be within a 5 cm to 7 cm RMSE of the source LiDAR values. Values were very evenly distributed as plus and minus (average error 1 cm) resulting in digitized breaklines being a consistent representation of the LiDAR surface well within project accuracy requirements. 3) 3D breaklines were digitized to delineate all readily identifiable water bodies down to 2 meters in width for the purpose of a generally flattened cartographic appearance as well as delineating water polygons for points to reclassify as water in the ground surface model. Water surfaces were not artificially flattened; breaklines represent the best visual interpretation of the break between land and water points. Breaklines represent the water level at the time of flight. Hard breaks occur where the water level is significantly different between different flight days. 4) Additional supplemental breaklines were digitized for cliffs, hard breaks or other readily identifiable terrain features when not represented to within 0.5 m or less by the initial ground model classification. 5) Concurrent photogrammetric review was performed to identify any remaining ground classification edits required.

                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.
