AJ8472.The coordinates were established by GPS observations
AJ8472.and adjusted by the National Geodetic Survey in June 2019.
AJ8472
AJ8472.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8472.been affixed to the stable North American Tectonic Plate.
AJ8472
AJ8472.The coordinates are valid at the epoch date displayed above
AJ8472.which is a decimal equivalence of Year/Month/Day.
AJ8472
AJ8472.Due to the release of the International GNSS Service (IGS) 2014
AJ8472.realization of the International Terrestrial Reference Frame of 2014
AJ8472.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8472.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8472.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8472.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8472.currently published epoch of 2010.00.
AJ8472
AJ8472.Additional information on MYCS2 is available at
AJ8472.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ8472
AJ8472.The orthometric height was determined by GPS observations and a
AJ8472.high-resolution geoid model using precise GPS observation and
AJ8472.processing techniques.
AJ8472
AJ8472.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ8472.GEOID18 height accuracy estimate available here.
AJ8472
AJ8472.The PID for the CORS L1 Phase Center is DH9345.

AJ8472.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8472
AJ8472.The ellipsoidal height was determined by GPS observations
AJ8472.and is referenced to NAD 83.
