DK4179.The coordinates were established by GPS observations
DK4179.and adjusted by the National Geodetic Survey in June 2019.
DK4179
DK4179.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK4179.been affixed to the stable North American Tectonic Plate.
DK4179
DK4179.The coordinates are valid at the epoch date displayed above
DK4179.which is a decimal equivalence of Year/Month/Day.
DK4179
DK4179.Due to the release of the International GNSS Service (IGS) 2014
DK4179.realization of the International Terrestrial Reference Frame of 2014
DK4179.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK4179.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK4179.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK4179.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK4179.currently published epoch of 2010.00.
DK4179
DK4179.Additional information on MYCS2 is available at
DK4179.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK4179.Significant digits in the geoid height do not necessarily reflect accuracy.
DK4179.GEOID18 height accuracy estimate available here.

DK4179.The XYZ, and position/ellipsoidal ht. are equivalent.
DK4179
DK4179.The ellipsoidal height was determined by GPS observations
DK4179.and is referenced to NAD 83.
