AJ7188.The coordinates were established by GPS observations
AJ7188.and adjusted by the National Geodetic Survey in June 2019.
AJ7188
AJ7188.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ7188.been affixed to the stable North American Tectonic Plate.
AJ7188
AJ7188.The coordinates are valid at the epoch date displayed above
AJ7188.which is a decimal equivalence of Year/Month/Day.
AJ7188
AJ7188.Due to the release of the International GNSS Service (IGS) 2014
AJ7188.realization of the International Terrestrial Reference Frame of 2014
AJ7188.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ7188.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ7188.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ7188.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ7188.currently published epoch of 2010.00.
AJ7188
AJ7188.Additional information on MYCS2 is available at
AJ7188.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ7188.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ7188
AJ7188.The ellipsoidal height was determined by GPS observations
AJ7188.and is referenced to NAD 83.
