DG5771.The coordinates were established by GPS observations
DG5771.and adjusted by the National Geodetic Survey in June 2019.
DG5771
DG5771.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5771.been affixed to the stable North American Tectonic Plate.
DG5771
DG5771.The coordinates are valid at the epoch date displayed above
DG5771.which is a decimal equivalence of Year/Month/Day.
DG5771
DG5771.Due to the release of the International GNSS Service (IGS) 2014
DG5771.realization of the International Terrestrial Reference Frame of 2014
DG5771.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5771.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5771.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5771.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5771.currently published epoch of 2010.00.
DG5771
DG5771.Additional information on MYCS2 is available at
DG5771.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG5771
DG5771.The orthometric height was determined by GPS observations and a
DG5771.high-resolution geoid model using precise GPS observation and
DG5771.processing techniques.
DG5771
DG5771.Significant digits in the geoid height do not necessarily reflect accuracy.
DG5771.GEOID18 height accuracy estimate available here.
DG5771
DG5771.The PID for the CORS L1 Phase Center is DL5967.

DG5771
DG5771.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5771
DG5771.The ellipsoidal height was determined by GPS observations
DG5771.and is referenced to NAD 83.
