DG4137.The coordinates were established by GPS observations
DG4137.and adjusted by the National Geodetic Survey in July 2022.
DG4137
DG4137.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG4137.been affixed to the stable North American Tectonic Plate.
DG4137
DG4137.The coordinates are valid at the epoch date displayed above
DG4137.which is a decimal equivalence of Year/Month/Day.
DG4137
DG4137.Due to the release of the International GNSS Service (IGS) 2014
DG4137.realization of the International Terrestrial Reference Frame of 2014
DG4137.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG4137.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG4137.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG4137.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG4137.currently published epoch of 2010.00.
DG4137
DG4137.Additional information on MYCS2 is available at
DG4137.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG4137
DG4137.The orthometric height was determined by GPS observations and a
DG4137.high-resolution geoid model using precise GPS observation and
DG4137.processing techniques.
DG4137
DG4137.Significant digits in the geoid height do not necessarily reflect accuracy.
DG4137.GEOID18 height accuracy estimate available here.
DG4137
DG4137.The PID for the CORS L1 Phase Center is DG4138.

DG4137
DG4137.The XYZ, and position/ellipsoidal ht. are equivalent.
DG4137
DG4137.The ellipsoidal height was determined by GPS observations
DG4137.and is referenced to NAD 83.
