AI3283.The coordinates were established by GPS observations
AI3283.and adjusted by the National Geodetic Survey in June 2019.
AI3283
AI3283.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI3283.been affixed to the stable North American Tectonic Plate.
AI3283
AI3283.The coordinates are valid at the epoch date displayed above
AI3283.which is a decimal equivalence of Year/Month/Day.
AI3283
AI3283.Due to the release of the International GNSS Service (IGS) 2014
AI3283.realization of the International Terrestrial Reference Frame of 2014
AI3283.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI3283.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI3283.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI3283.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI3283.currently published epoch of 2010.00.
AI3283
AI3283.Additional information on MYCS2 is available at

AI3283.The XYZ, and position/ellipsoidal ht. are equivalent.
AI3283
AI3283.The ellipsoidal height was determined by GPS observations
AI3283.and is referenced to NAD 83.
