DH3879.The coordinates were established by GPS observations
DH3879.and adjusted by the National Geodetic Survey in June 2019.
DH3879
DH3879.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3879.been affixed to the stable North American Tectonic Plate.
DH3879
DH3879.The coordinates are valid at the epoch date displayed above
DH3879.which is a decimal equivalence of Year/Month/Day.
DH3879
DH3879.Due to the release of the International GNSS Service (IGS) 2014
DH3879.realization of the International Terrestrial Reference Frame of 2014
DH3879.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3879.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3879.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3879.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3879.currently published epoch of 2010.00.
DH3879
DH3879.Additional information on MYCS2 is available at

DH3879.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3879.GEOID18 height accuracy estimate available here.

DH3879.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3879
DH3879.The ellipsoidal height was determined by GPS observations
DH3879.and is referenced to NAD 83.
