DF6303.The coordinates were established by GPS observations
DF6303.and adjusted by the National Geodetic Survey in June 2019.
DF6303
DF6303.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF6303.been affixed to the stable North American Tectonic Plate.
DF6303
DF6303.The coordinates are valid at the epoch date displayed above
DF6303.which is a decimal equivalence of Year/Month/Day.
DF6303
DF6303.Due to the release of the International GNSS Service (IGS) 2014
DF6303.realization of the International Terrestrial Reference Frame of 2014
DF6303.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF6303.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF6303.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF6303.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF6303.currently published epoch of 2010.00.
DF6303
DF6303.Additional information on MYCS2 is available at
DF6303.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF6303.Significant digits in the geoid height do not necessarily reflect accuracy.
DF6303.GEOID18 height accuracy estimate available here.

DF6303.The XYZ, and position/ellipsoidal ht. are equivalent.
DF6303
DF6303.The ellipsoidal height was determined by GPS observations
DF6303.and is referenced to NAD 83.
