DH3625.The coordinates were established by GPS observations
DH3625.and adjusted by the National Geodetic Survey in June 2022.
DH3625
DH3625.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3625.been affixed to the stable North American Tectonic Plate.
DH3625
DH3625.The coordinates are valid at the epoch date displayed above
DH3625.which is a decimal equivalence of Year/Month/Day.
DH3625
DH3625.Due to the release of the International GNSS Service (IGS) 2014
DH3625.realization of the International Terrestrial Reference Frame of 2014
DH3625.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3625.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3625.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3625.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3625.currently published epoch of 2010.00.
DH3625
DH3625.Additional information on MYCS2 is available at

DH3625.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3625
DH3625.The ellipsoidal height was determined by GPS observations
DH3625.and is referenced to NAD 83.
