AF9613.The coordinates were established by GPS observations
AF9613.and adjusted by the National Geodetic Survey in June 2019.
AF9613
AF9613.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9613.been affixed to the stable North American Tectonic Plate.
AF9613
AF9613.The coordinates are valid at the epoch date displayed above
AF9613.which is a decimal equivalence of Year/Month/Day.
AF9613
AF9613.Due to the release of the International GNSS Service (IGS) 2014
AF9613.realization of the International Terrestrial Reference Frame of 2014
AF9613.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9613.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9613.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9613.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9613.currently published epoch of 2010.00.
AF9613
AF9613.Additional information on MYCS2 is available at

AF9613.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9613
AF9613.The ellipsoidal height was determined by GPS observations
AF9613.and is referenced to NAD 83.
