DH4120.The coordinates were established by GPS observations
DH4120.and adjusted by the National Geodetic Survey in June 2019.
DH4120
DH4120.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH4120.been affixed to the stable North American Tectonic Plate.
DH4120
DH4120.The coordinates are valid at the epoch date displayed above
DH4120.which is a decimal equivalence of Year/Month/Day.
DH4120
DH4120.Due to the release of the International GNSS Service (IGS) 2014
DH4120.realization of the International Terrestrial Reference Frame of 2014
DH4120.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH4120.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH4120.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH4120.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH4120.currently published epoch of 2010.00.
DH4120
DH4120.Additional information on MYCS2 is available at

DH4120.The XYZ, and position/ellipsoidal ht. are equivalent.
DH4120
DH4120.The ellipsoidal height was determined by GPS observations
DH4120.and is referenced to NAD 83.
