AF9484.The coordinates were established by GPS observations
AF9484.and adjusted by the National Geodetic Survey in May 2020.
AF9484
AF9484.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9484.been affixed to the stable North American Tectonic Plate.
AF9484
AF9484.The coordinates are valid at the epoch date displayed above
AF9484.which is a decimal equivalence of Year/Month/Day.
AF9484
AF9484.Due to the release of the International GNSS Service (IGS) 2014
AF9484.realization of the International Terrestrial Reference Frame of 2014
AF9484.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9484.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9484.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9484.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9484.currently published epoch of 2010.00.
AF9484
AF9484.Additional information on MYCS2 is available at
AF9484.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9484.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9484.GEOID18 height accuracy estimate available here.

AF9484.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9484
AF9484.The ellipsoidal height was determined by GPS observations
AF9484.and is referenced to NAD 83.
