low tide
conditions. The Lidar data was processed to deliver topographic surface elevation data of the exposed
intertidal flats and surrounding
terrestrial areas.

Supplemental Information:
The tide patterns of Willapa Bay required that the project area be divided into three sections, and Lidar
flights had to be flown in an East/West orientation to capture the low, low tide conditions. As the tidal
waters moved throughout
the Bay, flights were completed according to tide data provided by the University of California - Davis
(Evolution & Ecology Dept.).
Flights were completed during all acceptable periods - day or night.

Name of measure:
Accuracy
Evaluation method description:
Independent ground control points were acquired using static GPS methods in flat open areas throughout the
project area. These points were estimated to have a vertical accuracy of 0.02m. The processed lidar data
were compared to ground
control points within the project. Lidar points surrounding the x-y of each ground control point were
located. A triangulated irregular
network (TIN) model was created and a z value was interpolated. The interpolated Lidar z value at ground
control x-y was compared to
the ground control z. The mean elevation difference for all comparison was used to estimate and remove an
elevation bias within the
Lidar data. The elevation bias was determined to be 0.137m. Removal of the bias resulted in a RMSE of
0.128m. Processing steps
(datum conversion, projection, grid interpolation, etc.) introduce additional error factors which have not
been tested and factored
into the reported error.

2978-foot swaths flown with 30% sidelap, 24,000 pulses per second; 1+1 collection (one return and one

Lidar flown with an ADS40, Leica Geosystems Lidar system, February 2002 model. The flight consisted of 71
E/W flight lines with 2 N/S
cross flight lines for data calibration purposes: 800 flight line miles covering 274 square miles. For
each lift, 2 flight lines were
flown at the Astoria, OR airport for system calibration purposes.

Description:
The raw lidar data was checked for complete coverage following each mission and at the end of the
flights.
The data was pre-processed using SBG software to correctly establish the position of each x-y-z point.
The data was checked
again for completeness and conformance to specifications by comparisons to ground surveyed points. The
Lidar data was post-processed
using a customized version of TerraSolid software and bare earth terrain models were developed.

Process step:
Process step:
Description:
The post-processed data from Spencer B. Gross were delivered in Washington State Plane (South)
projection
referenced to NAD27 with vertical elevations in US survey feet referenced to NGVD29. The data were
converted to geographic
coordinates using General Cartographic Transformation Program software developed by the United States
Geological Survey. The data
were then transformed to NAD83 using NADCON grids from the National Geodetic Survey (NGS). A final
datum transformation was
performed to convert vertical elevations referenced to NGVD29 to NAVD88 using NGS VERTCON grids. A
comparison of the lidar data to
a ground truth data set indicated a 0.137m bias, which was removed. The data were then converted to a
binary format and loaded
into the Lidar Data Retrieval Tool (LDART) database.
