DH7156.The coordinates were established by GPS observations
DH7156.and adjusted by the National Geodetic Survey in June 2019.
DH7156
DH7156.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7156.been affixed to the stable North American Tectonic Plate.
DH7156
DH7156.The coordinates are valid at the epoch date displayed above
DH7156.which is a decimal equivalence of Year/Month/Day.
DH7156
DH7156.Due to the release of the International GNSS Service (IGS) 2014
DH7156.realization of the International Terrestrial Reference Frame of 2014
DH7156.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7156.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7156.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7156.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7156.currently published epoch of 2010.00.
DH7156
DH7156.Additional information on MYCS2 is available at

DH7156.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7156.GEOID18 height accuracy estimate available here.

DH7156.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7156
DH7156.The ellipsoidal height was determined by GPS observations
DH7156.and is referenced to NAD 83.
