AH5056.The coordinates were established by GPS observations
AH5056.and adjusted by the National Geodetic Survey in June 2019.
AH5056
AH5056.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH5056.been affixed to the stable North American Tectonic Plate.
AH5056
AH5056.The coordinates are valid at the epoch date displayed above
AH5056.which is a decimal equivalence of Year/Month/Day.
AH5056
AH5056.Due to the release of the International GNSS Service (IGS) 2014
AH5056.realization of the International Terrestrial Reference Frame of 2014
AH5056.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH5056.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH5056.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH5056.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH5056.currently published epoch of 2010.00.
AH5056
AH5056.Additional information on MYCS2 is available at
AH5056.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH5056.Significant digits in the geoid height do not necessarily reflect accuracy.

AH5056.The XYZ, and position/ellipsoidal ht. are equivalent.
AH5056
AH5056.The ellipsoidal height was determined by GPS observations
AH5056.and is referenced to NAD 83.
