AJ6812.The coordinates were established by GPS observations
AJ6812.and adjusted by the National Geodetic Survey in June 2019.
AJ6812
AJ6812.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ6812.been affixed to the stable North American Tectonic Plate.
AJ6812
AJ6812.The coordinates are valid at the epoch date displayed above
AJ6812.which is a decimal equivalence of Year/Month/Day.
AJ6812
AJ6812.Due to the release of the International GNSS Service (IGS) 2014
AJ6812.realization of the International Terrestrial Reference Frame of 2014
AJ6812.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ6812.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ6812.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ6812.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ6812.currently published epoch of 2010.00.
AJ6812
AJ6812.Additional information on MYCS2 is available at
AJ6812.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ6812.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ6812
AJ6812.The ellipsoidal height was determined by GPS observations
AJ6812.and is referenced to NAD 83.
