DF8974.The coordinates were established by GPS observations
DF8974.and adjusted by the National Geodetic Survey in June 2020.
DF8974
DF8974.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8974.been affixed to the stable North American Tectonic Plate.
DF8974
DF8974.The coordinates are valid at the epoch date displayed above
DF8974.which is a decimal equivalence of Year/Month/Day.
DF8974
DF8974.Due to the release of the International GNSS Service (IGS) 2014
DF8974.realization of the International Terrestrial Reference Frame of 2014
DF8974.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8974.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8974.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8974.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8974.currently published epoch of 2010.00.
DF8974
DF8974.Additional information on MYCS2 is available at
DF8974.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8974.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8974.GEOID18 height accuracy estimate available here.

DF8974.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8974
DF8974.The ellipsoidal height was determined by GPS observations
DF8974.and is referenced to NAD 83.
