AJ6818.The coordinates were established by GPS observations
AJ6818.and adjusted by the National Geodetic Survey in June 2019.
AJ6818
AJ6818.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ6818.been affixed to the stable North American Tectonic Plate.
AJ6818
AJ6818.The coordinates are valid at the epoch date displayed above
AJ6818.which is a decimal equivalence of Year/Month/Day.
AJ6818
AJ6818.Due to the release of the International GNSS Service (IGS) 2014
AJ6818.realization of the International Terrestrial Reference Frame of 2014
AJ6818.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ6818.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ6818.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ6818.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ6818.currently published epoch of 2010.00.
AJ6818
AJ6818.Additional information on MYCS2 is available at
AJ6818.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ6818.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ6818
AJ6818.The ellipsoidal height was determined by GPS observations
AJ6818.and is referenced to NAD 83.
