AJ4870.The coordinates were established by GPS observations
AJ4870.and adjusted by the National Geodetic Survey in June 2019.
AJ4870
AJ4870.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ4870.been affixed to the stable North American Tectonic Plate.
AJ4870
AJ4870.The coordinates are valid at the epoch date displayed above
AJ4870.which is a decimal equivalence of Year/Month/Day.
AJ4870
AJ4870.Due to the release of the International GNSS Service (IGS) 2014
AJ4870.realization of the International Terrestrial Reference Frame of 2014
AJ4870.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4870.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4870.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4870.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4870.currently published epoch of 2010.00.
AJ4870
AJ4870.Additional information on MYCS2 is available at
AJ4870.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ4870.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ4870.GEOID18 height accuracy estimate available here.

AJ4870.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4870
AJ4870.The ellipsoidal height was determined by GPS observations
AJ4870.and is referenced to NAD 83.
