DK6554.The coordinates were established by GPS observations
DK6554.and adjusted by the National Geodetic Survey in June 2019.
DK6554
DK6554.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK6554.been affixed to the stable North American Tectonic Plate.
DK6554
DK6554.The coordinates are valid at the epoch date displayed above
DK6554.which is a decimal equivalence of Year/Month/Day.
DK6554
DK6554.Due to the release of the International GNSS Service (IGS) 2014
DK6554.realization of the International Terrestrial Reference Frame of 2014
DK6554.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK6554.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK6554.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK6554.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK6554.currently published epoch of 2010.00.
DK6554
DK6554.Additional information on MYCS2 is available at
DK6554.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK6554.Significant digits in the geoid height do not necessarily reflect accuracy.

DK6554.The XYZ, and position/ellipsoidal ht. are equivalent.
DK6554
DK6554.The ellipsoidal height was determined by GPS observations
DK6554.and is referenced to NAD 83.
