DF7481.The coordinates were established by GPS observations
DF7481.and adjusted by the National Geodetic Survey in June 2019.
DF7481
DF7481.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7481.been affixed to the stable North American Tectonic Plate.
DF7481
DF7481.The coordinates are valid at the epoch date displayed above
DF7481.which is a decimal equivalence of Year/Month/Day.
DF7481
DF7481.Due to the release of the International GNSS Service (IGS) 2014
DF7481.realization of the International Terrestrial Reference Frame of 2014
DF7481.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7481.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7481.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7481.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7481.currently published epoch of 2010.00.
DF7481
DF7481.Additional information on MYCS2 is available at
DF7481.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF7481.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7481.GEOID18 height accuracy estimate available here.

DF7481.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7481
DF7481.The ellipsoidal height was determined by GPS observations
DF7481.and is referenced to NAD 83.
