AI8820.The coordinates were established by GPS observations
AI8820.and adjusted by the National Geodetic Survey in June 2019.
AI8820
AI8820.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI8820.been affixed to the stable North American Tectonic Plate.
AI8820
AI8820.The coordinates are valid at the epoch date displayed above
AI8820.which is a decimal equivalence of Year/Month/Day.
AI8820
AI8820.Due to the release of the International GNSS Service (IGS) 2014
AI8820.realization of the International Terrestrial Reference Frame of 2014
AI8820.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI8820.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI8820.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI8820.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI8820.currently published epoch of 2010.00.
AI8820
AI8820.Additional information on MYCS2 is available at

AI8820.The XYZ, and position/ellipsoidal ht. are equivalent.
AI8820
AI8820.The ellipsoidal height was determined by GPS observations
AI8820.and is referenced to NAD 83.
