AI2153.The coordinates were established by GPS observations
AI2153.and adjusted by the National Geodetic Survey in June 2019.
AI2153
AI2153.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI2153.been affixed to the stable North American Tectonic Plate.
AI2153
AI2153.The coordinates are valid at the epoch date displayed above
AI2153.which is a decimal equivalence of Year/Month/Day.
AI2153
AI2153.Due to the release of the International GNSS Service (IGS) 2014
AI2153.realization of the International Terrestrial Reference Frame of 2014
AI2153.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI2153.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI2153.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI2153.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI2153.currently published epoch of 2010.00.

AI2153.Additional information on MYCS2 is available at

AI2153.The XYZ, and position/ellipsoidal ht. are equivalent.
AI2153
AI2153.The ellipsoidal height was determined by GPS observations
AI2153.and is referenced to NAD 83.
