DF9200.The coordinates were established by GPS observations
DF9200.and adjusted by the National Geodetic Survey in July 2023.
DF9200
DF9200.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF9200.been affixed to the stable North American Tectonic Plate.
DF9200
DF9200.The coordinates are valid at the epoch date displayed above
DF9200.which is a decimal equivalence of Year/Month/Day.
DF9200
DF9200.Due to the release of the International GNSS Service (IGS) 2014
DF9200.realization of the International Terrestrial Reference Frame of 2014
DF9200.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF9200.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF9200.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF9200.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF9200.currently published epoch of 2010.00.
DF9200
DF9200.Additional information on MYCS2 is available at
DF9200.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF9200.Significant digits in the geoid height do not necessarily reflect accuracy.
DF9200.GEOID18 height accuracy estimate available here.

DF9200.The XYZ, and position/ellipsoidal ht. are equivalent.
DF9200
DF9200.The ellipsoidal height was determined by GPS observations
DF9200.and is referenced to NAD 83.
