DK7557.The coordinates were established by GPS observations
DK7557.and adjusted by the National Geodetic Survey in June 2022.
DK7557
DK7557.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7557.been affixed to the stable North American Tectonic Plate.
DK7557
DK7557.The coordinates are valid at the epoch date displayed above
DK7557.which is a decimal equivalence of Year/Month/Day.
DK7557
DK7557.Due to the release of the International GNSS Service (IGS) 2014
DK7557.realization of the International Terrestrial Reference Frame of 2014
DK7557.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7557.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7557.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7557.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7557.currently published epoch of 2010.00.
DK7557
DK7557.Additional information on MYCS2 is available at
DK7557.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7557
DK7557.The orthometric height was determined by GPS observations and a
DK7557.high-resolution geoid model using precise GPS observation and
DK7557.processing techniques.
DK7557
DK7557.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7557.GEOID18 height accuracy estimate available here.

DK7557.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7557
DK7557.The ellipsoidal height was determined by GPS observations
DK7557.and is referenced to NAD 83.
