AJ3139.The coordinates were established by GPS observations
AJ3139.and adjusted by the National Geodetic Survey in June 2019.
AJ3139
AJ3139.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ3139.been affixed to the stable North American Tectonic Plate.
AJ3139
AJ3139.The coordinates are valid at the epoch date displayed above
AJ3139.which is a decimal equivalence of Year/Month/Day.
AJ3139
AJ3139.Due to the release of the International GNSS Service (IGS) 2014
AJ3139.realization of the International Terrestrial Reference Frame of 2014
AJ3139.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ3139.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ3139.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ3139.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ3139.currently published epoch of 2010.00.
AJ3139
AJ3139.Additional information on MYCS2 is available at
AJ3139.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ3139.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ3139.GEOID18 height accuracy estimate available here.

AJ3139.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ3139
AJ3139.The ellipsoidal height was determined by GPS observations
AJ3139.and is referenced to NAD 83.
