AF9652.The coordinates were established by GPS observations
AF9652.and adjusted by the National Geodetic Survey in June 2019.
AF9652
AF9652.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9652.been affixed to the stable North American Tectonic Plate.
AF9652
AF9652.The coordinates are valid at the epoch date displayed above
AF9652.which is a decimal equivalence of Year/Month/Day.
AF9652
AF9652.Due to the release of the International GNSS Service (IGS) 2014
AF9652.realization of the International Terrestrial Reference Frame of 2014
AF9652.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9652.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9652.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9652.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9652.currently published epoch of 2010.00.
AF9652
AF9652.Additional information on MYCS2 is available at
AF9652.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9652.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9652.GEOID18 height accuracy estimate available here.

AF9652.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9652
AF9652.The ellipsoidal height was determined by GPS observations
AF9652.and is referenced to NAD 83.
