DK4049.The coordinates were established by GPS observations
DK4049.and adjusted by the National Geodetic Survey in June 2019.
DK4049
DK4049.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK4049.been affixed to the stable North American Tectonic Plate.
DK4049
DK4049.The coordinates are valid at the epoch date displayed above
DK4049.which is a decimal equivalence of Year/Month/Day.
DK4049
DK4049.Due to the release of the International GNSS Service (IGS) 2014
DK4049.realization of the International Terrestrial Reference Frame of 2014
DK4049.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK4049.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK4049.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK4049.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK4049.currently published epoch of 2010.00.
DK4049
DK4049.Additional information on MYCS2 is available at
DK4049.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK4049.Significant digits in the geoid height do not necessarily reflect accuracy.
DK4049.GEOID18 height accuracy estimate available here.

DK4049.The XYZ, and position/ellipsoidal ht. are equivalent.
DK4049
DK4049.The ellipsoidal height was determined by GPS observations
DK4049.and is referenced to NAD 83.
