DF7992.The coordinates were established by GPS observations
DF7992.and adjusted by the National Geodetic Survey in June 2019.
DF7992
DF7992.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7992.been affixed to the stable North American Tectonic Plate.
DF7992
DF7992.The coordinates are valid at the epoch date displayed above
DF7992.which is a decimal equivalence of Year/Month/Day.
DF7992
DF7992.Due to the release of the International GNSS Service (IGS) 2014
DF7992.realization of the International Terrestrial Reference Frame of 2014
DF7992.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7992.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7992.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7992.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7992.currently published epoch of 2010.00.
DF7992
DF7992.Additional information on MYCS2 is available at
DF7992.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF7992.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7992.GEOID18 height accuracy estimate available here.

DF7992.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7992
DF7992.The ellipsoidal height was determined by GPS observations
DF7992.and is referenced to NAD 83.
