DK3593.The coordinates were established by GPS observations
DK3593.and adjusted by the National Geodetic Survey in June 2019.
DK3593
DK3593.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK3593.been affixed to the stable North American Tectonic Plate.
DK3593
DK3593.The coordinates are valid at the epoch date displayed above
DK3593.which is a decimal equivalence of Year/Month/Day.
DK3593
DK3593.Due to the release of the International GNSS Service (IGS) 2014
DK3593.realization of the International Terrestrial Reference Frame of 2014
DK3593.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK3593.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK3593.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK3593.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK3593.currently published epoch of 2010.00.
DK3593
DK3593.Additional information on MYCS2 is available at
DK3593.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK3593.The XYZ, and position/ellipsoidal ht. are equivalent.
DK3593
DK3593.The ellipsoidal height was determined by GPS observations
DK3593.and is referenced to NAD 83.
