Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data of the
Wenatchee USGS area of interest (AOI) east of Wenatchee, WA on May 1nd - May 28th, 2009.
The total area of delivered LiDAR is 278,232 acres. The requested area was
expanded to include a 100 m buffer to ensure complete coverage and adequate point
densities around survey area boundaries.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
Provide high resolution terrain elevation and land cover elevation data.
Please credit the Puget Sound LiDAR Consortium (PSLC) for these data. The PSLC is supported by the Puget Sound Regional Council,

Accuracy
Elevations are recorded in floating-point meters and the vertical datum is ellipsoidal (GEOID03).
Horizontal Positional Accuracy
Horizontal positional accuracy for LiDAR is dependent upon the quality of
the GPS/INS solution, sensor calibration and ground conditions at the time of data capture.
The standard system results for horizontal accuracy are less than 1 meter. Not reported, assumed as 1.0 m.
; Quantitative Value: 1.0 meters, Test that produced the value: See LiDAR data report.
Vertical Positional Accuracy
Review the report cited as supplemental information above for details on accuracy assessment.; Quantitative Value: 0.036 meters, Test that produced the value:
Summary statistics for point resolution and
accuracy (relative and absolute) of the LiDAR data collected in the Douglas County
survey area are presented below in terms of central tendency, variation around
the mean, and the spatial distribution of the data (for point resolution by bin).
Calculated to 0.12 ft at 1-sigma.
Completeness Report
LiDAR data has been collected and processed for all areas within the project study area.
Conceptual Consistency
The vertical accuracy of the LiDAR data is described as the mean and standard deviation
(1 sigma) of divergence of LiDAR point coordinates from RTK ground survey point
coordinates. To provide a sense of the model predictive power of the dataset, the root mean
square error (RMSE) for vertical accuracy is also provided. These statistics assume the error
distributions for x, y, and z are normally distributed, thus we also consider the skew and
kurtosis of distributions when evaluating error statistics.
Statements of statistical accuracy apply to fixed terrestrial surfaces only and may not be
applied to areas of dense vegetation or steep terrain. To calibrate laser accuracy for the
LiDAR dataset, 4930 RTK ground survey points were collected on fixed, hard-packed road
surfaces within the survey area.
Acquisition.
The lidar survey uses a Leica ALS50 Phase II laser system. For the Wenatchee USGS survey
area, the sensor scan angle +/- 14 degrees from nadir with a pulse rate designed to yield an
average native density (number of pulses emitted by the laser system) of more than 8 points
per square meter over terrestrial surfaces. All survey areas were surveyed with an opposing
flight line side-lap of more than 50% (less than 100% overlap) to reduce laser shadowing and
increase surface laser painting. The Leica ALS50 Phase II system allows up to four range
measurements (returns) per pulse, and all discernible laser returns were processed for the
output dataset. It is not uncommon for some types of surfaces (e.g. dense vegetation or water)
to return fewer pulses than the laser originally emitted. These discrepancies between 'native'
and 'delivered' density will vary depending on terrain, land cover and the prevalence of water
bodies.
To accurately solve for laser points position (geographic coordinates x, y, z) the positional
coordinates of the airborne sensor and the attitude of the aircraft were recorded continuously
throughout the lidar data collection mission. Aircraft position was measured twice per
second (2 Hz) by an onboard differential GPS unit. Aircraft attitude was measured 200 times
per second (200 Hz) as pitch, roll, yaw (heading) from an onboard inertial measurement unit(IMU).
To allow for post-processing correction and calibration, aircraft/sensor position and attitude
data are indexed by GPS time.

Resolved kinematic corrections for aircraft position data using kinematic aircraft GPS and
static ground GPS data.
Software - Waypoint GPS v.8.10, Trimble Geomatics Office v.1.62
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 v.1.4
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 v1.1) format.
Software: ALS Post Processing Software v.2.69
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.9.001
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.9.001
Position and attitude data were imported. Resulting data were classified as ground and nonground
points. Statistical absolute accuracy was assessed via direct comparisons of ground
classified points to ground RTK survey data. Data were then converted to orthometric
elevations (NAVD88) by applying a Geoid03 correction. Ground models were created as a
triangulated surface and exported as ArcInfo ASCII grids at a 3-foot pixel resolution.
Software - TerraScan v.9.001, ArcMap v.9.3, TerraModeler v.9.001

The NOAA Office for Coastal Management (OCM) downloaded topographic files in LAZ format from PSLC's website.
The files contained lidar easting, northing, elevation, intensity, return number, class, scan angle
and GPS time measurements; the data was received in state plane Washington (in feet) and vertical coordinates were
referenced to NAVD88 in feet using the Geoid03 model.
OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The All-Return LAZ files were checked for bad elevations
2. The laz files were converted from a Projected Coordinate System (SP 4602) to a Geographic Coordinate system (NAD83)
3. The laz files were then converted to ellipsoidal vertical units in meters using the geoid03 conversion.
2013-12-02T00:00:00
The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
