Watershed Sciences, Inc. (WSI) collected Light Detection and Ranging (LiDAR) data for the Lewis County survey area
for the Puget Sound LiDAR Consortium. This data set covers approximately 547 square miles. Delivery 1 of the survey
area was collected on July 18th, 19th and 20th of 2009.
The LiDAR survey utilized both a Leica ALS60 and a Leica ALS50-II sensor in a Cessna Caravan 208B. All areas were
surveyed with an opposing flight line side-lap of 50% (=100% overlap) to reduce laser shadowing and increase
surface laser painting. The Leica laser systems allow up to four range measurements (returns) per pulse,
and all discernible laser returns were processed for the output dataset.
This LiDAR survey achieved a nominal point spacing of 8.82 points per square meter.

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.

the National Aeronautical and Space Administration (NASA), the United States Geological Survey (USGS) and numerous
partners in local, state, and tribal government. For more information, visit <http://pugetsoundlidar.ess.washington.edu/>

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.
Elevation values for open water surfaces are not valid elevation values because few LiDAR points are returned
from water surfaces. Triangles were created across water surfaces by interpolating from the nearest land points

Accuracy
Elevations are recorded in floating-point meters and the vertical datum is ellipsoidal (GEOID03).
There are no other attribute tables.
Horizontal Positional Accuracy
See LiDAR data report.
Vertical Positional Accuracy
See LiDAR data report.; Quantitative Value: 0.030 meters, Test that produced the value: The Root Mean Square Error (RMSE) of the data set is 0.10 feet.
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 50% 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.
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 the IPAS survey
suite and ALS Post Processing 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 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 broken into processing bins and output areas
and output as laser points, TINed and GRIDed surfaces. Bare earth DEMs meet PSLC specification.

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. ASCII xyz files were parsed to LAS files.
2. The topographic LAS files were converted from orthometric (NAVD88) heights to ellipsoidal
heights using Geoid03.
3. The topographic LAS files were converted from a Projected Coordinate System (WA SP South)
to a Geographic Coordinate system (NAD83).
4. The topographic LAS files' vertical units were converted from feet to meters.
5. The topographic LAS files' were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid)
heights using Geoid03.
6. The topographic LAS files were geotagged and header information was updated.
