AF9699.The coordinates were established by GPS observations
AF9699.and adjusted by the National Geodetic Survey in June 2019.
AF9699
AF9699.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9699.been affixed to the stable North American Tectonic Plate.
AF9699
AF9699.The coordinates are valid at the epoch date displayed above
AF9699.which is a decimal equivalence of Year/Month/Day.
AF9699
AF9699.Due to the release of the International GNSS Service (IGS) 2014
AF9699.realization of the International Terrestrial Reference Frame of 2014
AF9699.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9699.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9699.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9699.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9699.currently published epoch of 2010.00.
AF9699
AF9699.Additional information on MYCS2 is available at
