<br /> NOTES
<br /> j THE PURPOSE OF THIS SURVEY IS TO ESTABLISH A HORIZONTAL AND VERTICAL CONTROL NETWORK FOR THE
<br /> 1 CITY OF TRACY. THE NETWORK IS DESIGNED TO ACHIEVE LOCAL ELLIPSOID HEIGHT ACCURACIES OF 2cm AS
<br /> OUTLINED IN "GUIDE-LINES FOR ESTABLISHING GPS-DERIVED ELLIPSOID HEIGHTS (2CM STANDARDS)" ,
<br /> VERSION 4.3, PUBLISHED BY NATIONAL GEODETIC SURVEY. CARRIER-PHASE-DIFFERENCED GLOBAL
<br /> POSITIONING SYSTEM (GPS) SURVEYING TECHNIQUES WERE UTILIZED FOR HORIZONTAL AND VERTICAL CONTROL
<br /> ON THIS PROJECT. F7IELD EQUIPMENT USED FOR THIS SURVEY INCLUDED TRIMBLE 4800 AND R8 RECEIVERS
<br /> ALONG WITH FIXED HEIGHT TRIPODS. OBSERVATIONS WERE PROCESSED AND ADJUSTED USING TRIMBLE
<br /> a,
<br /> GEOMATICS OFFICE, VERSION 1 .63. MODELED GEOID HEIGHTS (GEOID 2003) WERE ADDED TO OBSERVED
<br /> ELLIPSOID HEIGHTS TO OBTAIN ELEVATIONS.
<br /> BASED UPON THE FINAL CONSTRAINED LEAST SQUARES NETWORK ADJUSTMENT OF THE GPS BASELINES, THE RMS
<br /> OF THE ABSOLUTE RESIDUALS WAS 0.026 FEET HORIZONTAL AND 0.028 FEET VERTICAL. THE ERROR
<br /> 0
<br /> MCHB ELLIPSES, EVALUATED AT THE 95% CONFIDENCE LEVEL (2 SIGMA) , HAD A MEAN VALUE OF THE MAJOR AXIS
<br /> LEGEND OF 0.036 FEET HORIZONTAL AND 0.035 FEET VERTICAL.
<br /> A CONTINUOUS OPERATING REFERENCE STATION (CORS)
<br /> THIS RECORD OF SURVEY IS INTENDED TO BE USED AS A HORIZONTAL AND VERTICAL CONTROL MAP ONLY. NO
<br /> 0 SET 2" CITY OF TRACY HORIZONTAL CONTROL & BENCHMARK AS NOTED ON SHEETS 3-5 ATTEMPT WAS MADE TO IDENTIFY OR RESOLVE BOUNDARY LINES.
