AJ8056.The coordinates were established by GPS observations
AJ8056.and adjusted by the National Geodetic Survey in June 2019.
AJ8056
AJ8056.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8056.been affixed to the stable North American Tectonic Plate.
AJ8056
AJ8056.The coordinates are valid at the epoch date displayed above
AJ8056.which is a decimal equivalence of Year/Month/Day.
AJ8056
AJ8056.Due to the release of the International GNSS Service (IGS) 2014
AJ8056.realization of the International Terrestrial Reference Frame of 2014
AJ8056.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8056.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8056.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8056.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8056.currently published epoch of 2010.00.
AJ8056
AJ8056.Additional information on MYCS2 is available at
AJ8056.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ8056.Significant digits in the geoid height do not necessarily reflect accuracy.

AJ8056.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8056
AJ8056.The ellipsoidal height was determined by GPS observations
AJ8056.and is referenced to NAD 83.
