DF8992.The coordinates were established by GPS observations
DF8992.and adjusted by the National Geodetic Survey in June 2019.
DF8992
DF8992.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8992.been affixed to the stable North American Tectonic Plate.
DF8992
DF8992.The coordinates are valid at the epoch date displayed above
DF8992.which is a decimal equivalence of Year/Month/Day.
DF8992
DF8992.Due to the release of the International GNSS Service (IGS) 2014
DF8992.realization of the International Terrestrial Reference Frame of 2014
DF8992.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8992.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8992.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8992.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8992.currently published epoch of 2010.00.
DF8992
DF8992.Additional information on MYCS2 is available at
DF8992.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8992.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8992.GEOID18 height accuracy estimate available here.

DF8992.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8992
DF8992.The ellipsoidal height was determined by GPS observations
DF8992.and is referenced to NAD 83.
