DL7644.The coordinates were established by GPS observations
DL7644.and adjusted by the National Geodetic Survey in June 2019.
DL7644
DL7644.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7644.been affixed to the stable North American Tectonic Plate.
DL7644
DL7644.The coordinates are valid at the epoch date displayed above
DL7644.which is a decimal equivalence of Year/Month/Day.
DL7644
DL7644.Due to the release of the International GNSS Service (IGS) 2014
DL7644.realization of the International Terrestrial Reference Frame of 2014
DL7644.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7644.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7644.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7644.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7644.currently published epoch of 2010.00.
DL7644
DL7644.Additional information on MYCS2 is available at
