AJ4428.The coordinates were established by GPS observations
AJ4428.and adjusted by the National Geodetic Survey in June 2019.
AJ4428
AJ4428.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ4428.been affixed to the stable North American Tectonic Plate.
AJ4428
AJ4428.The coordinates are valid at the epoch date displayed above
AJ4428.which is a decimal equivalence of Year/Month/Day.
AJ4428
AJ4428.Due to the release of the International GNSS Service (IGS) 2014
AJ4428.realization of the International Terrestrial Reference Frame of 2014
AJ4428.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4428.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4428.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4428.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4428.currently published epoch of 2010.00.
AJ4428
AJ4428.Additional information on MYCS2 is available at
AJ4428.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ4428.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ4428.GEOID18 height accuracy estimate available here.

AJ4428.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4428
AJ4428.The ellipsoidal height was determined by GPS observations
AJ4428.and is referenced to NAD 83.
