DK4124.The coordinates were established by GPS observations
DK4124.and adjusted by the National Geodetic Survey in June 2019.
DK4124
DK4124.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK4124.been affixed to the stable North American Tectonic Plate.
DK4124
DK4124.The coordinates are valid at the epoch date displayed above
DK4124.which is a decimal equivalence of Year/Month/Day.
DK4124
DK4124.Due to the release of the International GNSS Service (IGS) 2014
DK4124.realization of the International Terrestrial Reference Frame of 2014
DK4124.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK4124.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK4124.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK4124.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK4124.currently published epoch of 2010.00.
DK4124
DK4124.Additional information on MYCS2 is available at
DK4124.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK4124.Significant digits in the geoid height do not necessarily reflect accuracy.
DK4124.GEOID18 height accuracy estimate available here.

DK4124.The XYZ, and position/ellipsoidal ht. are equivalent.
DK4124
DK4124.The ellipsoidal height was determined by GPS observations
DK4124.and is referenced to NAD 83.
