DH9021.The coordinates were established by GPS observations
DH9021.and adjusted by the National Geodetic Survey in June 2019.
DH9021
DH9021.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH9021.been affixed to the stable North American Tectonic Plate.
DH9021
DH9021.The coordinates are valid at the epoch date displayed above
DH9021.which is a decimal equivalence of Year/Month/Day.
DH9021
DH9021.Due to the release of the International GNSS Service (IGS) 2014
DH9021.realization of the International Terrestrial Reference Frame of 2014
DH9021.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH9021.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH9021.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH9021.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH9021.currently published epoch of 2010.00.
DH9021
DH9021.Additional information on MYCS2 is available at

DH9021.The XYZ, and position/ellipsoidal ht. are equivalent.
DH9021
DH9021.The ellipsoidal height was determined by GPS observations
DH9021.and is referenced to NAD 83.
