* » Abstract |
Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data of the Upper Naches River Valley and Nile Slide area of interest on September 30th, 2011-October 1st, 2011 and April 5th, 2012 for the Puget Sound LiDAR Consortium. The valley bottom was reflown in 2012 during "leaf-off" conditions, to ensure a more detailed bare earth model, and matched with the upslope data from 2011 to provide a seamless dataset. The requested area was expanded to include a 100m buffer to ensure complete coverage and adequate point densities around survey area boundaries. The total acreage of this delivery is 23,771 acres of LiDAR data. The LiDAR survey utilized a Leica ALS60 sensor in a Cessna Caravan 208B. Please see "Project Report" below for specific information regarding the airborne survey and ground survey. This Lidar survey acheived a nominal point spacing of 11.60 points per square meter. |
* Purpose |
The LAS files can be used to create DEMs and also to extract topographic data in software that does not support raster data. Other surface features can also be extracted with custom applications. LiDAR data has a wide range of uses such as earthquake hazard studies, hydrologic modeling, forestry, coastal engineering, roadway and pipeline engineering, flood plain mapping, wetland studies, geologic studies and a variety of analytical and cartographic projects. |

Accuracy |
Elevations are recorded in floating-point meters and the vertical datum is ellipsoidal (GEOID03). There are no other attribute tables. |
Analytical Accuracy | |
Horizontal Positional Accuracy |
Not applicable for pure elevation data: every XY error has an associated Z error. |
Vertical Positional Accuracy |
See the "Project Report" above for a detailed accuracy report.; Quantitative Value: 0.0236 meters, Test that produced the value: Root mean square Z error in open, near-horizontal areas, as specified by contract. Units in meters. Accuracy may be significantly less in steep areas and under heavy forest canopy. |

Completeness Report |
Elevation data has been collected for all areas inside project boundaries. The data set was flown with a 60% sidelap between flightlines and a 100 meter buffer to ensure all areas are properly sampled. |
Conceptual Consistency |
Puget Sound Lidar Consortium evaluates logical consistency of high-resolution lidar elevation data with three tests: examination of file names, file formats, and mean and extreme values within each file; internal consistency of measured Z values in areas where survey swaths overlap; and visual inspection of shaded-relief images calculated from bare-earth models. File names, formats, and values: All file naming convention and file formats are checked for consistency. Visual inspection of bare earth surfaces were examined to find any obvious data errors such as blunders, border artifacts, gaps between data quads, no-data gaps between flight lines, hillscarps, land shifting due to GPS time errors, etc. |

1. Resolved kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. Software: Waypoint GPS v.8.10, Trimble Business Center v.2.6 2. Developed a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with attitude data. Sensor head position and attitude were calculated throughout the survey. The SBET data were used extensively for laser point processing. Software: IPAS TC v.3.1 3. Calculated laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Created raw laser point cloud data for the entire survey in *.las (ASPRS v. 1.2) format. Data were then converted to orthometric elevations (NAVD88) by applying a Geoid03 correction. Software: ALS Post Processing Software v.2.74 4. Imported raw laser points into manageable blocks (less than 500 MB) to perform manual relative accuracy calibration and filter for pits/birds. Ground points were then classified for individual flight lines (to be used for relative accuracy testing and calibration). Software: TerraScan v.12.004 5. Using ground classified points per each flight line, the relative accuracy was tested. Automated line-to-line calibrations were then performed for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calibrations were performed on ground classified points from paired flight lines. Every flight line was used for relative accuracy calibration. Software: TerraMatch v.12.001 6. Position and attitude data were imported. Resulting data were classified as ground and non-ground points. Statistical absolute accuracy was assessed via direct comparisons of ground classified points to ground RTK survey data. Software: TerraScan v.12.004, TerraModeler v.12.002 7. Final version of data was checked for duplicate points using TerraScan software. No duplicate points were found. Software: TerraScan v.12.004, TerraModeler v.12.002 8. Bare Earth models were created as a triangulated surface and exported as ArcInfo ASCII grids at a 3-foot pixel resolution. Highest Hit models were created for any class at 3-foot grid spacing and exported as ArcInfo ASCII grids. Software: TerraScan v.12.004, ArcMap v. 10.0, TerraModeler v.12.002 |

» Description |
The NOAA Office for Coastal Management (OCM) downloaded topographic files in .LAZ format from PSLC's website. The files contained lidar elevation and intensity measurements. The data were received in Washington State Plane South Zone 4602, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic laz files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03. 2. The topographic laz files were converted from a Projected Coordinate System (WA SP South) to a Geographic Coordinate system (NAD83). 3. The topographic laz files' vertical units were converted from feet to meters. 4. The topographic laz files' horizontal units were converted from feet to decimal degrees. |
