AI8811.The coordinates were established by GPS observations
AI8811.and adjusted by the National Geodetic Survey in June 2019.
AI8811
AI8811.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI8811.been affixed to the stable North American Tectonic Plate.
AI8811
AI8811.The coordinates are valid at the epoch date displayed above
AI8811.which is a decimal equivalence of Year/Month/Day.
AI8811
AI8811.Due to the release of the International GNSS Service (IGS) 2014
AI8811.realization of the International Terrestrial Reference Frame of 2014
AI8811.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI8811.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI8811.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI8811.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI8811.currently published epoch of 2010.00.

AI8811.The XYZ, and position/ellipsoidal ht. are equivalent.
AI8811
AI8811.The ellipsoidal height was determined by GPS observations
AI8811.and is referenced to NAD 83.
