AH8303.The coordinates were established by GPS observations
AH8303.and adjusted by the National Geodetic Survey in June 2019.
AH8303
AH8303.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH8303.been affixed to the stable North American Tectonic Plate.
AH8303
AH8303.The coordinates are valid at the epoch date displayed above
AH8303.which is a decimal equivalence of Year/Month/Day.
AH8303
AH8303.Due to the release of the International GNSS Service (IGS) 2014
AH8303.realization of the International Terrestrial Reference Frame of 2014
AH8303.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH8303.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH8303.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH8303.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH8303.currently published epoch of 2010.00.
AH8303
AH8303.Additional information on MYCS2 is available at
AH8303.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH8303.Significant digits in the geoid height do not necessarily reflect accuracy.

AH8303.The XYZ, and position/ellipsoidal ht. are equivalent.
AH8303
AH8303.The ellipsoidal height was determined by GPS observations
AH8303.and is referenced to NAD 83.
