AJ2122.The coordinates were established by GPS observations
AJ2122.and adjusted by the National Geodetic Survey in June 2019.
AJ2122
AJ2122.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ2122.been affixed to the stable North American Tectonic Plate.
AJ2122
AJ2122.The coordinates are valid at the epoch date displayed above
AJ2122.which is a decimal equivalence of Year/Month/Day.
AJ2122
AJ2122.Due to the release of the International GNSS Service (IGS) 2014
AJ2122.realization of the International Terrestrial Reference Frame of 2014
AJ2122.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ2122.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ2122.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ2122.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ2122.currently published epoch of 2010.00.

AJ2122.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ2122
AJ2122.The ellipsoidal height was determined by GPS observations
AJ2122.and is referenced to NAD 83.
