DN7401.The coordinates were established by GPS observations
DN7401.and adjusted by the National Geodetic Survey in June 2019.
DN7401
DN7401.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7401.been affixed to the stable North American Tectonic Plate.
DN7401
DN7401.The coordinates are valid at the epoch date displayed above
DN7401.which is a decimal equivalence of Year/Month/Day.
DN7401
DN7401.Due to the release of the International GNSS Service (IGS) 2014
DN7401.realization of the International Terrestrial Reference Frame of 2014
DN7401.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7401.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7401.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7401.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7401.currently published epoch of 2010.00.
DN7401
DN7401.Additional information on MYCS2 is available at

DN7401.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7401
DN7401.The ellipsoidal height was determined by GPS observations
DN7401.and is referenced to NAD 83.
