DK7737.The coordinates were established by GPS observations
DK7737.and adjusted by the National Geodetic Survey in June 2019.
DK7737
DK7737.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7737.been affixed to the stable North American Tectonic Plate.
DK7737
DK7737.The coordinates are valid at the epoch date displayed above
DK7737.which is a decimal equivalence of Year/Month/Day.
DK7737
DK7737.Due to the release of the International GNSS Service (IGS) 2014
DK7737.realization of the International Terrestrial Reference Frame of 2014
DK7737.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7737.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7737.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7737.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7737.currently published epoch of 2010.00.
DK7737
DK7737.Additional information on MYCS2 is available at
DK7737.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK7737.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7737.GEOID18 height accuracy estimate available here.

DK7737.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7737
DK7737.The ellipsoidal height was determined by GPS observations
DK7737.and is referenced to NAD 83.
