AJ1820.The coordinates were established by GPS observations
AJ1820.and adjusted by the National Geodetic Survey in June 2019.
AJ1820
AJ1820.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ1820.been affixed to the stable North American Tectonic Plate.
AJ1820
AJ1820.The coordinates are valid at the epoch date displayed above
AJ1820.which is a decimal equivalence of Year/Month/Day.
AJ1820
AJ1820.Due to the release of the International GNSS Service (IGS) 2014
AJ1820.realization of the International Terrestrial Reference Frame of 2014
AJ1820.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ1820.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ1820.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ1820.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ1820.currently published epoch of 2010.00.
AJ1820
AJ1820.Additional information on MYCS2 is available at
AJ1820.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ1820.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ1820.GEOID18 height accuracy estimate available here.

AJ1820.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ1820
AJ1820.The ellipsoidal height was determined by GPS observations
AJ1820.and is referenced to NAD 83.
