DL7647.The coordinates were established by GPS observations
DL7647.and adjusted by the National Geodetic Survey in June 2019.
DL7647
DL7647.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7647.been affixed to the stable North American Tectonic Plate.
DL7647
DL7647.The coordinates are valid at the epoch date displayed above
DL7647.which is a decimal equivalence of Year/Month/Day.
DL7647
DL7647.Due to the release of the International GNSS Service (IGS) 2014
DL7647.realization of the International Terrestrial Reference Frame of 2014
DL7647.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7647.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7647.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7647.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7647.currently published epoch of 2010.00.
DL7647
DL7647.Additional information on MYCS2 is available at

DL7647.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7647
DL7647.The ellipsoidal height was determined by GPS observations
DL7647.and is referenced to NAD 83.
