Comments:
The RTK GPS base station for this SWATH Bathymetry survey is called "WCMG"
An NAD83(CORS96) (Epoch 2002.0000) coordinate for "WCMG" was obtained using the average of 10 independent OPUS solutions (observeded in April/May 2010).
Source Point Name: "WCMG-2002-001"

Semi-major axis(meters): 6378137.00000000
Semi-minor axis(meters): 6356752.31414036
Eccentricity: 0.08181919104281582
Inverse Flattening: 298.257222101
Vertical Reference: Ellipsoidal Height

Geodetic longitude (Degree): W 122 03 19.32478
Ellipsoidal height (Meter): 4.138
This average coordinate was transformed to an ITRF00 (WGS84[G1150]), Epoch 2010-230 coordinate (SWATH survey date) using the software program "Geographic Calculator" from Blue Marble Geographics.
The output file "bmg-WCMG-NAD83-ITRF00-2010-230.txt" uploaded to this Basecamp project contains the transformation information.
These ITRF00 coordinate values were used to program the RTK GPS base.
