DL6420.The coordinates were established by GPS observations
DL6420.and adjusted by the National Geodetic Survey in June 2019.
DL6420
DL6420.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6420.been affixed to the stable North American Tectonic Plate.
DL6420
DL6420.The coordinates are valid at the epoch date displayed above
DL6420.which is a decimal equivalence of Year/Month/Day.
DL6420
DL6420.Due to the release of the International GNSS Service (IGS) 2014
DL6420.realization of the International Terrestrial Reference Frame of 2014
DL6420.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6420.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6420.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6420.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6420.currently published epoch of 2010.00.
