The study area totals 2899 square miles (1,855,159 acres). The data were collected in 17 deliveries, from 2009 through 2011. The bare earth digital elevation model (DEM) represents the earth's surface with all vegetation and human-made structures removed. The bare earth DEMs were derived from lidar data using TIN processing of the ground point returns. The DEM grid cell size is 3 feet. Some elevation values have been interpolated across areas in the models where there is no elevation data (e.g. over water, over dense vegetation). In addition to the bare earth DEMs, the topobathy lidar point data are also available. A link to the lidar point data is provided in the URL section of this metadata record.

It is the responsibility of the user to determine whether or not the data is suitable for the intended purpose. otherRestrictions Access Constraints: None otherRestrictions Use Constraints: In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. TINing the points produces large triangles and hence the elevations may be less accurate within such areas. In some areas with large bodies of water, competing water surface levels may be visible. This is due to seasonal water level fluctuation and intervals of time between acquisition of an area. Users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions.

Vertical Positional Accuracy The Root Mean Square Error (RMSE) of the data set is 0.04 meters. Accuracy was assessed using 31,073 ground survey (real time kinematic) points. These ground survey points are distributed through out the study area. Completeness Report LiDAR data has been collected and processed for all areas within the project study area. Conceptual Consistency 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 1:3000 scale. Watershed Sciences, Inc. has collected Light Detection and Ranging (LiDAR) data of the Deschutes Study Area for the Oregon Department of Geology and Mineral Industries (DOGAMI). The area of interest (AOI) totals 3,001 square miles (1,920,429 acres) and the total area flown (TAF) covers 3,053 square miles (1,953,949 acres). The TAF acreage is greater than the original AOI acreage due to buffering and flight planning optimization (Figure 1.1 below). DOGAMI data are delivered in OGIC (HARN): Projection: Oregon Statewide Lambert Conformal Conic; horizontal and vertical datum: NAD83 (HARN)/NAVD88 (Geoid03); units: International Feet. The LiDAR survey utilized Leica ALS50 Phase II and ALS60 sensors mounted in multiple Cessna Caravan 208Bs. The Leica systems were set to acquire greater than or equal to 105,000 laser pulses per second (i.e. 105 kHz pulse rate) and flown at 900 and 1300 meters above ground level (AGL), capturing a scan angle of plus or minus 14 degrees from nadir. These settings are developed to yield points with an average native density of 8 points per square meter over terrestrial surfaces. The native pulse density is the number of pulses emitted by the LiDAR system. Some types of surfaces (i.e. dense vegetation or water) may return fewer pulses than the laser originally emitted. Therefore, the delivered density can be less than the native density and vary according to distributions of terrain, land cover and water bodies. 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 Office for Coastal Management (OCM) received the data in the proprietary ESRI grid format from DOGAMI. The bare earth raster files were at a 3 ft grid spacing. The data were in Oregon Statewide Lambert (NAD83 HARN) International feet coordinates and NAVD88 (Geoid03) elevations in International feet. OCM did the following processing to the data for Digital Coast storage and provisioning purposes: 1. Converted the raster files from the proprietary ESRI grid format to floating point GEOTIFF format 2. Converted the raster files from elevations in international feet to meters using gdal_translate from GDAL version 2.1.1. 3. Copied the raster files to database and https 2017-10-10T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Files were converted to cloud optimized geotiff format to support streaming and the vertical units were reverted to feet to match the horizontal units. 2023-08-17T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor DEM files DOGAMI originator
