AH5046.The coordinates were established by GPS observations
AH5046.and adjusted by the National Geodetic Survey in June 2019.
AH5046
AH5046.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH5046.been affixed to the stable North American Tectonic Plate.
AH5046
AH5046.The coordinates are valid at the epoch date displayed above
AH5046.which is a decimal equivalence of Year/Month/Day.
AH5046
AH5046.Due to the release of the International GNSS Service (IGS) 2014
AH5046.realization of the International Terrestrial Reference Frame of 2014
AH5046.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH5046.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH5046.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH5046.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH5046.currently published epoch of 2010.00.
AH5046
AH5046.Additional information on MYCS2 is available at
AH5046.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH5046.Significant digits in the geoid height do not necessarily reflect accuracy.

AH5046.The XYZ, and position/ellipsoidal ht. are equivalent.
AH5046
AH5046.The ellipsoidal height was determined by GPS observations
AH5046.and is referenced to NAD 83.
