DG4691.The coordinates were established by GPS observations
DG4691.and adjusted by the National Geodetic Survey in June 2019.
DG4691
DG4691.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG4691.been affixed to the stable North American Tectonic Plate.
DG4691
DG4691.The coordinates are valid at the epoch date displayed above
DG4691.which is a decimal equivalence of Year/Month/Day.
DG4691
DG4691.Due to the release of the International GNSS Service (IGS) 2014
DG4691.realization of the International Terrestrial Reference Frame of 2014
DG4691.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG4691.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG4691.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG4691.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG4691.currently published epoch of 2010.00.
DG4691
DG4691.Additional information on MYCS2 is available at
DG4691.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG4691
DG4691.The orthometric height was determined by GPS observations and a
DG4691.high-resolution geoid model using precise GPS observation and
DG4691.processing techniques.
DG4691
DG4691.Significant digits in the geoid height do not necessarily reflect accuracy.
DG4691.GEOID18 height accuracy estimate available here.
DG4691
DG4691.The PID for the CORS L1 Phase Center is DP2651.

DG4691.The XYZ, and position/ellipsoidal ht. are equivalent.
DG4691
DG4691.The ellipsoidal height was determined by GPS observations
DG4691.and is referenced to NAD 83.
