DG5942.The coordinates were established by GPS observations
DG5942.and adjusted by the National Geodetic Survey in July 2022.
DG5942
DG5942.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5942.been affixed to the stable North American Tectonic Plate.
DG5942
DG5942.The coordinates are valid at the epoch date displayed above
DG5942.which is a decimal equivalence of Year/Month/Day.
DG5942
DG5942.Due to the release of the International GNSS Service (IGS) 2014
DG5942.realization of the International Terrestrial Reference Frame of 2014
DG5942.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5942.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5942.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5942.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5942.currently published epoch of 2010.00.
DG5942
DG5942.Additional information on MYCS2 is available at

DG5942.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5942
DG5942.The ellipsoidal height was determined by GPS observations
DG5942.and is referenced to NAD 83.
