AJ8053.The coordinates were established by GPS observations
AJ8053.and adjusted by the National Geodetic Survey in June 2019.
AJ8053
AJ8053.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8053.been affixed to the stable North American Tectonic Plate.
AJ8053
AJ8053.The coordinates are valid at the epoch date displayed above
AJ8053.which is a decimal equivalence of Year/Month/Day.
AJ8053
AJ8053.Due to the release of the International GNSS Service (IGS) 2014
AJ8053.realization of the International Terrestrial Reference Frame of 2014
AJ8053.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8053.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8053.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8053.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8053.currently published epoch of 2010.00.
AJ8053
AJ8053.Additional information on MYCS2 is available at
AJ8053.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ8053.Significant digits in the geoid height do not necessarily reflect accuracy.

AJ8053.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8053
AJ8053.The ellipsoidal height was determined by GPS observations
AJ8053.and is referenced to NAD 83.
