DG9294.The coordinates were established by GPS observations
DG9294.and adjusted by the National Geodetic Survey in June 2019.
DG9294
DG9294.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9294.been affixed to the stable North American Tectonic Plate.
DG9294
DG9294.The coordinates are valid at the epoch date displayed above
DG9294.which is a decimal equivalence of Year/Month/Day.
DG9294
DG9294.Due to the release of the International GNSS Service (IGS) 2014
DG9294.realization of the International Terrestrial Reference Frame of 2014
DG9294.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9294.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9294.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9294.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9294.currently published epoch of 2010.00.

DG9294.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9294
DG9294.The ellipsoidal height was determined by GPS observations
DG9294.and is referenced to NAD 83.
