AJ4430.The coordinates were established by GPS observations
AJ4430.and adjusted by the National Geodetic Survey in June 2019.
AJ4430
AJ4430.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ4430.been affixed to the stable North American Tectonic Plate.
AJ4430
AJ4430.The coordinates are valid at the epoch date displayed above
AJ4430.which is a decimal equivalence of Year/Month/Day.
AJ4430
AJ4430.Due to the release of the International GNSS Service (IGS) 2014
AJ4430.realization of the International Terrestrial Reference Frame of 2014
AJ4430.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4430.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4430.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4430.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4430.currently published epoch of 2010.00.
AJ4430
AJ4430.Additional information on MYCS2 is available at
AJ4430.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ4430.Significant digits in the geoid height do not necessarily reflect accuracy.

AJ4430.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4430
AJ4430.The ellipsoidal height was determined by GPS observations
AJ4430.and is referenced to NAD 83.
