DH7954.The coordinates were established by GPS observations
DH7954.and adjusted by the National Geodetic Survey in June 2019.
DH7954
DH7954.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7954.been affixed to the stable North American Tectonic Plate.
DH7954
DH7954.The coordinates are valid at the epoch date displayed above
DH7954.which is a decimal equivalence of Year/Month/Day.
DH7954
DH7954.Due to the release of the International GNSS Service (IGS) 2014
DH7954.realization of the International Terrestrial Reference Frame of 2014
DH7954.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7954.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7954.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7954.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7954.currently published epoch of 2010.00.
DH7954
DH7954.Additional information on MYCS2 is available at
DH7954.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH7954.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7954.GEOID18 height accuracy estimate available here.

DH7954.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7954
DH7954.The ellipsoidal height was determined by GPS observations
DH7954.and is referenced to NAD 83.
