AH8904.The coordinates were established by GPS observations
AH8904.and adjusted by the National Geodetic Survey in June 2019.
AH8904
AH8904.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH8904.been affixed to the stable North American Tectonic Plate.
AH8904
AH8904.The coordinates are valid at the epoch date displayed above
AH8904.which is a decimal equivalence of Year/Month/Day.
AH8904
AH8904.Due to the release of the International GNSS Service (IGS) 2014
AH8904.realization of the International Terrestrial Reference Frame of 2014
AH8904.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH8904.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH8904.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH8904.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH8904.currently published epoch of 2010.00.
AH8904
AH8904.Additional information on MYCS2 is available at
AH8904.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH8904
AH8904.The orthometric height was determined by GPS observations and a
AH8904.high-resolution geoid model using precise GPS observation and
AH8904.processing techniques.
AH8904
AH8904.Significant digits in the geoid height do not necessarily reflect accuracy.
AH8904.GEOID18 height accuracy estimate available here.
AH8904
AH8904.The PID for the CORS L1 Phase Center is AJ7957.

AH8904
AH8904.The XYZ, and position/ellipsoidal ht. are equivalent.
AH8904
AH8904.The ellipsoidal height was determined by GPS observations
AH8904.and is referenced to NAD 83.
