DF9223.The coordinates were established by GPS observations
DF9223.and adjusted by the National Geodetic Survey in February 2020.
DF9223
DF9223.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF9223.been affixed to the stable North American Tectonic Plate.
DF9223
DF9223.The coordinates are valid at the epoch date displayed above
DF9223.which is a decimal equivalence of Year/Month/Day.
DF9223
DF9223.Due to the release of the International GNSS Service (IGS) 2014
DF9223.realization of the International Terrestrial Reference Frame of 2014
DF9223.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF9223.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF9223.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF9223.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF9223.currently published epoch of 2010.00.
DF9223
DF9223.Additional information on MYCS2 is available at
DF9223.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF9223.Significant digits in the geoid height do not necessarily reflect accuracy.
DF9223.GEOID18 height accuracy estimate available here.

DF9223.The XYZ, and position/ellipsoidal ht. are equivalent.
DF9223
DF9223.The ellipsoidal height was determined by GPS observations
DF9223.and is referenced to NAD 83.
