DH4126.The coordinates were established by GPS observations
DH4126.and adjusted by the National Geodetic Survey in June 2019.
DH4126
DH4126.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH4126.been affixed to the stable North American Tectonic Plate.
DH4126
DH4126.The coordinates are valid at the epoch date displayed above
DH4126.which is a decimal equivalence of Year/Month/Day.
DH4126
DH4126.Due to the release of the International GNSS Service (IGS) 2014
DH4126.realization of the International Terrestrial Reference Frame of 2014
DH4126.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH4126.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH4126.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH4126.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH4126.currently published epoch of 2010.00.
DH4126
DH4126.Additional information on MYCS2 is available at

DH4126.The XYZ, and position/ellipsoidal ht. are equivalent.
DH4126
DH4126.The ellipsoidal height was determined by GPS observations
DH4126.and is referenced to NAD 83.
