DF8984.The coordinates were established by GPS observations
DF8984.and adjusted by the National Geodetic Survey in July 2023.
DF8984
DF8984.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8984.been affixed to the stable North American Tectonic Plate.
DF8984
DF8984.The coordinates are valid at the epoch date displayed above
DF8984.which is a decimal equivalence of Year/Month/Day.
DF8984
DF8984.Due to the release of the International GNSS Service (IGS) 2014
DF8984.realization of the International Terrestrial Reference Frame of 2014
DF8984.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8984.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8984.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8984.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8984.currently published epoch of 2010.00.
DF8984
DF8984.Additional information on MYCS2 is available at
DF8984.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8984.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8984.GEOID18 height accuracy estimate available here.

DF8984.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8984
DF8984.The ellipsoidal height was determined by GPS observations
DF8984.and is referenced to NAD 83.
