DL6904.The coordinates were established by GPS observations
DL6904.and adjusted by the National Geodetic Survey in June 2019.
DL6904
DL6904.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6904.been affixed to the stable North American Tectonic Plate.
DL6904
DL6904.The coordinates are valid at the epoch date displayed above
DL6904.which is a decimal equivalence of Year/Month/Day.
DL6904
DL6904.Due to the release of the International GNSS Service (IGS) 2014
DL6904.realization of the International Terrestrial Reference Frame of 2014
DL6904.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6904.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6904.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6904.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6904.currently published epoch of 2010.00.
DL6904
DL6904.Additional information on MYCS2 is available at

DL6904.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6904
DL6904.The ellipsoidal height was determined by GPS observations
DL6904.and is referenced to NAD 83.
