DE9144.The coordinates were established by GPS observations
DE9144.and adjusted by the National Geodetic Survey in June 2019.
DE9144
DE9144.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DE9144.been affixed to the stable North American Tectonic Plate.
DE9144
DE9144.The coordinates are valid at the epoch date displayed above
DE9144.which is a decimal equivalence of Year/Month/Day.
DE9144
DE9144.Due to the release of the International GNSS Service (IGS) 2014
DE9144.realization of the International Terrestrial Reference Frame of 2014
DE9144.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE9144.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE9144.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE9144.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE9144.currently published epoch of 2010.00.
DE9144
DE9144.Additional information on MYCS2 is available at

DE9144.The XYZ, and position/ellipsoidal ht. are equivalent.
DE9144
DE9144.The ellipsoidal height was determined by GPS observations
DE9144.and is referenced to NAD 83.
