DG4257.The coordinates were established by GPS observations
DG4257.and adjusted by the National Geodetic Survey in June 2019.
DG4257
DG4257.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG4257.been affixed to the stable North American Tectonic Plate.
DG4257
DG4257.The coordinates are valid at the epoch date displayed above
DG4257.which is a decimal equivalence of Year/Month/Day.
DG4257
DG4257.Due to the release of the International GNSS Service (IGS) 2014
DG4257.realization of the International Terrestrial Reference Frame of 2014
DG4257.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG4257.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG4257.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG4257.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG4257.currently published epoch of 2010.00.
DG4257
DG4257.Additional information on MYCS2 is available at
DG4257.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG4257
DG4257.The orthometric height was determined by GPS observations and a
DG4257.high-resolution geoid model using precise GPS observation and
DG4257.processing techniques.
DG4257
DG4257.Significant digits in the geoid height do not necessarily reflect accuracy.
DG4257.GEOID18 height accuracy estimate available here.
DG4257
DG4257.The PID for the CORS L1 Phase Center is DL7123.

DG4257
DG4257.The XYZ, and position/ellipsoidal ht. are equivalent.
DG4257
DG4257.The ellipsoidal height was determined by GPS observations
DG4257.and is referenced to NAD 83.
