AI4945.The coordinates were established by GPS observations
AI4945.and adjusted by the National Geodetic Survey in June 2019.
AI4945
AI4945.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI4945.been affixed to the stable North American Tectonic Plate.
AI4945
AI4945.The coordinates are valid at the epoch date displayed above
AI4945.which is a decimal equivalence of Year/Month/Day.
AI4945
AI4945.Due to the release of the International GNSS Service (IGS) 2014
AI4945.realization of the International Terrestrial Reference Frame of 2014
AI4945.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI4945.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI4945.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI4945.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI4945.currently published epoch of 2010.00.

AI4945.Additional information on MYCS2 is available at

AI4945.The XYZ, and position/ellipsoidal ht. are equivalent.
AI4945
AI4945.The ellipsoidal height was determined by GPS observations
AI4945.and is referenced to NAD 83.
