DF3914.The coordinates were established by GPS observations
DF3914.and adjusted by the National Geodetic Survey in June 2019.
DF3914
DF3914.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF3914.been affixed to the stable North American Tectonic Plate.
DF3914
DF3914.The coordinates are valid at the epoch date displayed above
DF3914.which is a decimal equivalence of Year/Month/Day.
DF3914
DF3914.Due to the release of the International GNSS Service (IGS) 2014
DF3914.realization of the International Terrestrial Reference Frame of 2014
DF3914.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF3914.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF3914.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF3914.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF3914.currently published epoch of 2010.00.
DF3914
DF3914.Additional information on MYCS2 is available at

DF3914.Significant digits in the geoid height do not necessarily reflect accuracy.
DF3914.GEOID18 height accuracy estimate available here.

DF3914.The XYZ, and position/ellipsoidal ht. are equivalent.
DF3914
DF3914.The ellipsoidal height was determined by GPS observations
DF3914.and is referenced to NAD 83.
