DK6947.The coordinates were established by GPS observations
DK6947.and adjusted by the National Geodetic Survey in July 2020.
DK6947
DK6947.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK6947.been affixed to the stable North American Tectonic Plate.
DK6947
DK6947.The coordinates are valid at the epoch date displayed above
DK6947.which is a decimal equivalence of Year/Month/Day.
DK6947
DK6947.Due to the release of the International GNSS Service (IGS) 2014
DK6947.realization of the International Terrestrial Reference Frame of 2014
DK6947.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK6947.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK6947.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK6947.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK6947.currently published epoch of 2010.00.
DK6947
DK6947.Additional information on MYCS2 is available at
DK6947.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK6947.Significant digits in the geoid height do not necessarily reflect accuracy.
DK6947.GEOID18 height accuracy estimate available here.

DK6947.The XYZ, and position/ellipsoidal ht. are equivalent.
DK6947
DK6947.The ellipsoidal height was determined by GPS observations
DK6947.and is referenced to NAD 83.
