DE8093.The coordinates were established by GPS observations
DE8093.and adjusted by the National Geodetic Survey in July 2022.
DE8093
DE8093.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DE8093.been affixed to the stable North American Tectonic Plate.
DE8093
DE8093.The coordinates are valid at the epoch date displayed above
DE8093.which is a decimal equivalence of Year/Month/Day.
DE8093
DE8093.Due to the release of the International GNSS Service (IGS) 2014
DE8093.realization of the International Terrestrial Reference Frame of 2014
DE8093.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE8093.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE8093.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE8093.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE8093.currently published epoch of 2010.00.
DE8093
DE8093.Additional information on MYCS2 is available at

DE8093.The XYZ, and position/ellipsoidal ht. are equivalent.
DE8093
DE8093.The ellipsoidal height was determined by GPS observations
DE8093.and is referenced to NAD 83.
