AJ8474.The coordinates were established by GPS observations
AJ8474.and adjusted by the National Geodetic Survey in June 2019.
AJ8474
AJ8474.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8474.been affixed to the stable North American Tectonic Plate.
AJ8474
AJ8474.The coordinates are valid at the epoch date displayed above
AJ8474.which is a decimal equivalence of Year/Month/Day.
AJ8474
AJ8474.Due to the release of the International GNSS Service (IGS) 2014
AJ8474.realization of the International Terrestrial Reference Frame of 2014
AJ8474.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8474.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8474.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8474.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8474.currently published epoch of 2010.00.
AJ8474
AJ8474.Additional information on MYCS2 is available at
AJ8474.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ8474.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8474
AJ8474.The ellipsoidal height was determined by GPS observations
AJ8474.and is referenced to NAD 83.
