AI3289.The coordinates were established by GPS observations
AI3289.and adjusted by the National Geodetic Survey in June 2019.
AI3289
AI3289.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI3289.been affixed to the stable North American Tectonic Plate.
AI3289
AI3289.The coordinates are valid at the epoch date displayed above
AI3289.which is a decimal equivalence of Year/Month/Day.
AI3289
AI3289.Due to the release of the International GNSS Service (IGS) 2014
AI3289.realization of the International Terrestrial Reference Frame of 2014
AI3289.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI3289.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI3289.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI3289.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI3289.currently published epoch of 2010.00.
AI3289
AI3289.Additional information on MYCS2 is available at

AI3289.The XYZ, and position/ellipsoidal ht. are equivalent.
AI3289
AI3289.The ellipsoidal height was determined by GPS observations
AI3289.and is referenced to NAD 83.
