AJ4872.The coordinates were established by GPS observations
AJ4872.and adjusted by the National Geodetic Survey in June 2019.
AJ4872
AJ4872.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ4872.been affixed to the stable North American Tectonic Plate.
AJ4872
AJ4872.The coordinates are valid at the epoch date displayed above
AJ4872.which is a decimal equivalence of Year/Month/Day.
AJ4872
AJ4872.Due to the release of the International GNSS Service (IGS) 2014
AJ4872.realization of the International Terrestrial Reference Frame of 2014
AJ4872.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4872.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4872.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4872.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4872.currently published epoch of 2010.00.

AJ4872.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4872
AJ4872.The ellipsoidal height was determined by GPS observations
AJ4872.and is referenced to NAD 83.
